Assignments

Due before class on week 2:.

Create a portfolio post (be sure to categorize it under Student Portfolios). Your portfolio post should have three different sections. The first is “Hello” (written in a header font 3 or less). The post should include a picture that represents you in some way and that same image should be set as the “Featured Image” for your whole Portfolio post. In this section, tell us something about yourself. We will be adding to your Portfolio all semester. The second subsection should be headed with your grab bag noun (for example “Circus Tent”) again written in a header font 3 or less. In this section, you will talk about your design and print process for your grab bag noun. You need to include at least one screen shot from your design process and at least one photo of your final print. The third section is “20 objects”. In this section, please name your 20 objects and tell us a bit about each of them. This section must contain at least one (preferably several) screenshot of all 20 of your objects on a single build plane so that each can be seen well in at least one picture. This section is your opportunity to play with the program. Have fun with it! Try some Shape Generators! Try making something challenging, even if it doesn’t work! All of these things should take maybe 2 hours at home designing and writing.

Due before class on Week 3:

Add to your portfolio! Print at least one of your 20 objects and include photos of that print in your “20 objects” section. Add a new section (in a Header font) called “Moving parts”. Your next assignment is to print moving parts. This is your first taste of iteration in 3D printing. You will need to print and reprint until the parts move the way they are supposed to. Also, while you do this, think about what you’d like to do for your final Tinkercad project.

Due before class on Week 4:

Add a new section to your portfolio “Tinkercad Final Project: (whatever you are making)”. This project will be your final opus of what is possible for you to do in Tinkercad. Please make this project ambitious, not something you can do in a few hours, but something that is difficult to design/difficult to print/is well beyond anything you have attempted to construct in Tinkercad up to this moment. Your final Tinkercad print and design are not due until Week 5, so for next week, I’d like to see significant progress both in planning (what you’re going to make) and in the design process (how you’re going to make it). Your post should include at least one screen shot of your design process.

Due before class on Week 5

You and your partner’s print for the Silly/Serious class challenge should be ready to present. More importantly, your Final Tinkercad project print is to be presented to the class.

Due before class on Week 6

Document your Final Tinkercad project with a post of its own that goes through your design process in detail. This post can be built off of your previous post in your portfolio, but should include at least 4 pictures and loads of detail on the issues you had with the printing/designing process. Please categorize this post in Tinkercad Final Project. You and your partner should also have a short post for your Silly/Serious Class Challenge which should be categorized in Class Challenges. Your design assignment due is the Fusion 360 ring tutorial (which should be sized correctly, decorated using Meshmixer, and printed). Please create a new section in your portfolio for this project.

Due before class on Week 7

Create 20 objects in Fusion 360, document them, and print at least two of them. Create a new section in your portfolio for this project. Your ring may be one of your 20 objects, but for the rest, I strongly suggest you use the tools in “Create” and “Modify”. Fusion is a much more difficult program than Tinkercad, so don’t worry if your objects are not recognizable things like chairs and lamps.

Due before class on Week 8

Create a new post and categorize it in Fusion 360 Final Project. Document your progress planning and designing this project.

Due before class on Week 9

All outreach events are canceled due to CORVID19. For Week 9 finish your Fusion 360 Final Project digital design. Be sure to take multiple screen shots of the design process, you’ll need them for later, but the documentation for this project will be due the week after, so concentrate on making the design the best it can be. We will be meeting during class time using the WebEx format (you’ll get an email with more details within a few days).

Due before class on Week 10

Documentation for your Fusion 360 Final Project. Similar to the documentation for your Tinkercad final project, this should include at least 4 pictures and loads of detail on the issues you had with the printing/designing process (if you did manage to get some prints in before break). Categorize the post under Fusion Final Project. Also due are your answer to the second Class Challenge! This Challenge involves going to https://makerware.thingiverse.com/challenges , picking one of the challenges (or the challenge we were going to do in class which was “Make it Fly”) and either in pairs or on your own design something that will satisfy that challenge. You will also need to write a short post about it and categorize it under Class Challenges.

Due before class on Week 11

There’s only one more program which is OpenSCAD. Our first OpenSCAD assignment was to use the 3rd tutorial at https://sites.jmu.edu/3SPACE/project/designing-with-openscad/ (the site is down right now, but I’ve given the tutorial its own page on our site). The tutorial uses a for loop at the end to make a snowflake, and the assignment due is to make something impossible to print (chaos) using a for loop. I demonstrated how one might do that in class by just modifying Tony’s code. The point is to fill up space using for loops. Remember, part of the point is it should be unprintable!

Due before class on Week 12

Here is a quick-start guide to OpenSCAD by math-grrl. Your OpenSCAD 20 objects due (make 20 different objects using OpenSCAD). We will trouble-shoot your code in class if it has issues (also due is a for loop version of chaos if you didn’t use one for the previous week). Your portfolio should be updated with your work in OpenSCAD (chaos for-loop and 20 objects). All code should be posted separately under the category OpenSCAD code. Today is also your second chance for your equipment quiz if you haven’t already taken it.

Due before class on Week 13

Today we have another Class Challenge, Fix It! Everyone must bring to class a broken household object that we will figure out how to fix using 3D design (if we were in class, we would actually fix the objects). Also due are progress reports on your Final OpenSCAD project (this should be a separate post categorized under OpenSCAD Final Project) and a proposal (no design work yet) for your Final Final Project (separate post under Final Final Project). Your Final Final Project can use any/all of the design programs we used in class, or use another program altogether. The only requirement is that it be ambitious! Ideally, it should be so ambitious that you’re not sure you can do it.

Due before class on Week 14

Progress reports on your Final Project are due, as well as your Fix It! Class Challenge designs. Also due are any outstanding missing assignments (ask me if you have any missing assignments). This class is your last opportunity to present (or post about) any missing assignments for credit.

Due before class on Final’s Week

Your Final Final Project is due by the class Final Exam Time (3:30pm on Wednesday May 6). Your Final Final Project can use any/all of the design tools that we used this semester, its only requirement is that it be a challenge for you to make! Also, your Final Presentation blog post should be posted before class on Final’s week. There is no longer any synchronous requirement for this class. Your Final Presentation post should consist of at least four objects: your final projects for each of the three programs we used (Tinkercad, Fusion360, and OpenSCAD) and your Final Final Project. You should be sure to include anything that you’re particularly proud of that you did this semester. Your Final Presentation post should tell the story of you and this class, how you adapted to the printers and the various programs we used to create designs. Which design tools did you like? Which did you suffer through? Tell your story of the class in your own words in your Final Presentation!

3D Printing : Module 5 of 10

3D Printing is a form of additive technology manufacturing. An object is built-up layer-by-layer rather than being carved or sculpted out of a larger block of material. A common analogy is to refer to a 3D printer as a robotic glue-gun: the 3D printer squeezes out or "extrudes" melted plastic through a heated tip, while the head moves back and forth to print out the design. As the platform that the model sits on lowers, the model builds up, layer-by-layer.

8 Types of 3D Printing Processes

Get familiar with these common 3D printing methods and machines and learn what each brings to the build plate

3D printing machine. Image Credit: Pixel B/Shutterstock.com

When it comes to 3D printing, you’re only limited by your imagination. Nowadays, it’s easier to ask the question, “What can’t you print using this process?” rather than listing the long and never-ending list of what can be produced. 3D printing is able to make simple tools, pump out full-blown architectural models, and even create prosthetics.

Not all printing needs will be the same, and there are actually quite a few methods you can choose from. For instance, at Xometry, we offer nine unique 3D printing processes, and are always aiming to add more. Each of these processes has its own pros and cons. Some are better for working with metal, other styles cure with lasers, and some are built for beginners interested in trying printing for the first time. Up ahead, learn about the different types of 3D printing and get an idea of the strengths and weaknesses of each.

Polyjet Printing

While 3D printers may seem pretty futuristic, PolyJet printing is the closest thing to the good ol’ fashioned inkjet printing you’re probably most familiar with. These machines use print heads to sprinkle tiny droplets of photopolymer resin onto a build plate, which then get hardened by a UV light in layers. Xometry’s PolyJet machines are capable of full-color and multi-material prints, making them ideal for creating lifelike models and visual prototypes. Be warned, though, PolyJet materials are not known for durability and are not suitable for end-use components.

The photo below shows one of our PolyJet printers creating full-color parts:

Xometry's PolyJet 3D printer creating multi-color parts.

This table shows the materials a polyjet printer can use, what it can make, and its strengths.

Materials	Strengths	Common Applications	Dimensional Accuracy

2. Fused Deposition Modeling (FDM)

Fused deposition modeling (FDM) machines can be found anywhere from a desk of a hobbyist, to the manufacturing floors of production facilities like Xometrys. This popular method involves moving a plastic filament through a heated nozzle to melt it and build up a part layer by layer until the final product is finished. There are many different filament materials to choose from, whether you’re after a more rigid plastic or bendy thermoplastic elastomer.

The image below shows one of Xometrys industrial printers capable of producing parts up to three feet in length:

One of Xometry’s many industrial FDM 3D printers

This table shares the materials a fused deposition modeling printer uses, what it can make, and its advantages compared to other printers.

Materials	Strengths	Common Applications	Dimensional Accuracy

3. Stereolithography (SLA)

Stereolithography (SLA) was the first kind of 3D printing that everyday people could get their hands on. This printer uses a high-powered laser to cure liquid photopolymer on its build plate. The laser zips around in the shape of the part’s cross-section, curing it and getting it ready for the next layer. It works with a process called polymerization to build the item you’ve designed layer by layer. It’s a great printing option if you want to build intricate models or products. Xometry offers many different SLA materials, many of which are transparent and useful for creating parts that you need to see through.

The photo shows some parts created through Xometry’s SLA service:

Various transparent tags made using SLA 3D printing

This chart points out the strengths and uses for an SLA printer. It also shows the materials it can manage and the types of things it can create.

.css-706nk0{position:absolute;margin-left:-2em;margin-top:3px;font-size:0.5em;color:#22445f;opacity:0;} 4. selective laser sintering (sls).

Selective laser sintering (SLS) swaps in those well-known plastic filaments for powdered plastic; typically nylon. This machine spreads a thin layer of this powder using a device called a recoater, then traces out the part’s cross-section with a laser. During the tracing, the heat from the laser melts the powder and it fuses together. The build chamber piston will then lower slightly, and another layer of powder will be spread across, and the process repeats until your product comes to life. This type of printing method does not require support structures as the un-sintered powder encases the parts throughout the medium, supporting them. For this reason, many parts can be built simultaneously in a single build which makes this type of printing superb for creating lots of parts at the same time, while retaining accuracy and quality.

The following diagram shows how an SLS 3D printer system works:

SLS 3D printing system.

This table lays out the materials you can send through this printer, what it makes, and its advantages.

5. Multi-Jet Fusion (MJF)

Multi-jet fusion printing has a lot of moving parts. On these machines, a layer of plastic powder is deposited that’s then warmed up by a heating head. An inkjet-style array hovers over top and precisely sprays fusing and detailing agents into the powder. The heating elements fuse it all together, and the process repeats. Like SLS printing, MJF parts do not require support structures due to the powder-based method, and therefore many parts can be printed simultaneously both horizontally and vertically in the build chamber. At Xometry, we offer both rigid and flexible materials through MJF and multiple finishing options, such as dyeing and chemical vapor smoothing to enhance the prints further.

The image below is an example of a part made using MJF, which in this case, has also been dyed black:

Nylon 12 part printed using MJF with a dyed black finish.

The following table shares the materials you can use with an MJF printer, what it can create, and its advantages.

6. Direct Metal Laser Sintering (DMLS)

When you’re in the market for a process that can 3D print directly in metal, look to direct metal laser sintering (DMLS). Similar to selective laser sintering, DMLS machines deposit a thin layer of metallic powder, then use their powerful lasers to trace out each part’s cross section layer by layer, fusing the metallic particles together to form parts. Unlike SLS, support structures are required as the heat and stress generated by sintering metal is much greater than with plastics. Due to their size, high cost, and the extensive post-processing steps required on parts after printing is completed, DMLS machines tend to only be found in industrial shops, such as those within Xometry’s network.

This picture shows a DMLS printer at Xometry in the midst of sintering parts from steel powder:

DMLS 3D printer sintering steel powder to form parts.

The following chart breaks down what you can make with DMLS printers, the materials you can use, and what kind of applications it’s good for.

7. Electron Beam Melting (EBM)

If you dial up the difficulty level, you’ll come across printing methods such as electron beam melting (EBM). Like DMLS, these machines fall into the industrial category and require the related expertise. Its process is all in the name—it uses electron beams to fuse metal particles together. The machine puts down a layer of metal powder, then the beam does the tracing and melting. The beam can even be split to tackle multiple areas all at once.

In this chart, you’ll see the materials an EBM 3D printer uses, what it can build, and its strengths.

8. Digital Light Process (DLP)

Some 3D printing options are similar to others, which is the case with digital light process (DLP) and SLA printers. The main difference is that a DLP machine will project an image using a UV light across the entire material vat at one time, instead of drawing the cross section one point at a time with a laser. Digital light processing has made access to photopolymer printing more accessible. It’s cheaper and faster than SLA, but it can still make high-quality parts.

This chart breaks down the materials, uses, and strengths of a DLP printer:

3D Printing Factors to Consider

There are all sorts of 3D printers out there for every kind of need. You’ll want to think about the end product you’re trying to build, the materials you’d like it to be made of, and the budget and timescale you have. If you’re looking for a printer you can have at home for enjoyment and low-key production, hobbyist FDM or SLA printers may fit the bill. More advanced printers, like DMLS machines, are a better fit for industrial spaces and industries like aerospace, engineering, or medicine.

24+ Best 3D Printing Projects for Engineers

Written by: Scott Hamill

February 20, 2024

3D printing projects for engineers are a step beyond easy beginner creations . These projects involve intricate, multi-part designs that require a significant level of skill, time, and effort.

If you’re an engineer, an avid builder, or simply someone looking for a challenging project with remarkable results, you’ve come to the right place.

I’ve curated a list of over my 24 favorite 3D printing projects specifically for engineers, ranging from intricate clocks to high-performance turbines and even robotic pets.

These projects not only serve as functional mechanisms but also as valuable educational tools for engineering students.

Whether you’re interested in timekeeping mechanisms like the Self-Winding Pendulum Clock , remote-controlled Cars , Planes , and Drones , or even making your own Robo-Pet companion, I’ve covered something for everyone

Dive into our list to discover these and many more exciting projects, and stay with us as we explore the future of 3D printing in engineering.

3D Printed Engineering Projects

Clocks – From Self-Winding to Smart Tech
RC Vehicles – Cars, Planes, and Drones
Turbines – Wind, Solar, and Hydroelectric
Robo-Pets – 3D Printed Robotic Cats and Dogs
Honorable Mentions – Drawing Machines, Robot Arms and More

Smart Clock

Hydroelectric turbine.

While simple enough by most engineering standards, clocks are excellent 3D printer projects for engineering students who are spreading their wings for the first time.

The best thing about 3D printing a clock as an engineering project is that it can be as complicated as you want it to be.

Traiaxial Tourbillon Clock

Designer : mcmaven

Price : Free

Mechanical Engineering 3D Printed Clock Project

Take this Triaxial Tourbillon Clock, for example.

Upgraded from the original design, it’s a fully functional clock that features better weight balancing and ball-bearing support to improve integrity as well as an overhauled internal mechanism to improve timekeeping accuracy.

Self-Winding Pendulum Clock

Designer : krahut

One of the coolest clocks I found that’s great as an engineering project is this self-winding pendulum clock. It’s a little more complicated for those of you looking for a challenging next project or engineering students wanting to expand their skills further.

Born as an upgrade to a previous pendulum clock design, the creator decided to make an even more complex self-winding mechanism that should keep itself going automatically for up to 200 days.

Upgrades to the self-winding pendulum clock

If you want to give yourself even more of a challenge, then why not try your hand at improving the mechanism from the files here to further increase its accuracy or lifespan?

Designer : Surrbradl08

If you prefer your timepieces on the digital side, or just prefer electrical engineering to mechanical, you can find plenty of awesome 3D printing projects like this smart clock to keep your mental motors running.

The thing about the smart clock is that it also requires some coding skills, using software systems to keep it going.

If you happen to have a hand in computer science as well as hardware technology, then it’s a great way to exercise multiple skills at once. If you don’t, however, then it could make for a fun collaborative project between engineering students or a joined effort if you want to get a differently-trained friend involved!

Of course, you can always try your hand at learning to code if you’re interested in using this kind of project as a learning experience.

These are just a few of the coolest clock projects for engineering students out there, but there are plenty more in so many styles and model types that should keep any engineer inspired and interested for a good long while.

RC Vehicles

3D printing toys are a good use of your printer if you have little ones in your life or if you just love to play with things. But as projects for engineers go, they’re often a little too simple.

A great way for engineers to practice their craft while making toys is by 3D printing remote-controlled vehicles.

Example Download : Cults3D

Designers : Varies

Price : Variable

There are a lot of 3D printable RC cars out there , with plenty of models mimicking real-life cars or taking on more traditional toy-like aesthetics and even the Batmobile.

In fact, by wiring up your car to the right size base, you can even make RC cars with swappable chassis for a fantastic, ever-changing toy.

If you’re good with a circuit board, you can make an RC car from scratch with a simple motor and remote sensor.

If you really want a challenge, though, then I recommend trying your hand at making airborne RC vehicles. 3D printed RC planes are really fun and a lot of the models online are unfinished and ripe for improvement, which is great news for you fixer-upper-loving engineers and and engineering students looking for some extra credit.

3D printed RC helicopter designs are few and far between, making them an excellent project for you engineers out there looking to make your mark on the 3D printing world.

In basic terms, because they aren’t naturally aerodynamic in shape, you’ll either have to design from scratch or piece together different printed parts like the blades, body, and landing equipment to cobble together your own working RC helicopter.

If you manage it, you can even sell your created design online, as there seems to be a gap in the market for good quality 3D printed RC helicopters out there now. The world will thank you and you could make some good scratch on the side.

If you’re still feeling more adventurous, a lot of engineers have taken to 3D printing their own drones as personal DIY project endeavours, some are even created with stands for Go-Pros, for more memorable excursions outdoors.

Like clocks, 3D printing drones can be as complicated or as simple in concept as you like. The real trick is getting your designs in the air, but once you do it you’ll know just how satisfying that particular feat is.

If you’re a dedicated engineer, you’ve probably already either learned or figured that it is possible to make turbines with a 3D printer. As you can see in our article here , wind turbines, both decorative and functional, are possible to 3D print.

While you can make wind turbines that are purely for aesthetic purposes , like a more complicated pinwheel, you probably aren’t here for that, and are instead looking for a DIY project that can actually power electronics.

So 3D printing wind turbines that actually generate energy is what we’ll look at here. Not only are they immensely satisfying to complete, they’re also great projects for engineering students who want to make something as impressive as it is practical.

If you’re an engineer looking to make your life a little eco-friendlier with your own designs, then 3D printing turbines for electronics is a fantastic way to go.

They are complex and very satisfying to make, if a little involved, and the end result is an alternative to your small-scale energy concerns while helping to make the world a little greener.

Of course, unless you have a lot of time on your hands, you shouldn’t expect to go printing something that’s going to power your whole house. But there are some very cool and completely functional 3D printed wind turbine designs.

50-Watt Turbine

Designer : 3dprintable1

The 50-watt turbine , for example, was designed to need little to nothing by way of post-processing or supports if printed using PLA material, which is quite an apt material for an energy-conscious project for electrical devices.

Those of you who know your filaments will likely be aware that PLA is one of the most biodegradable materials out there, making it one of the greenest.

While you shouldn’t expect this homemade turbine to power your car, it’s ideal for recharging batteries or low-scale home use like outdoor lighting. It is the little differences that all add up after all.

Solar Wind Turbine

Designer : PhilippHee

This combination 3D printed wind turbine and solar panel is a great project for any engineer looking to go greener still.

You will need some extra components to make it work at maximum efficiency, which you can either buy from the links included by the designer or find your own preferred parts.

The concept behind the design revolves around the solar panel using its stored energy to further power the turbine. But if you’re handy enough, you could work out a more efficient way to employ both power sources for domestic use.

Designer : mochr

If you’re lucky enough to have a river or stream run by your yard, then you can also 3D print water turbines and use hydroelectricity to power some of your home.

The most impressive one I could find was this functioning model of a hydroelectric power plant .

There’s something about having a pet. The companionship is priceless and the feeling of being needed is a sweet one indeed.

Of course, not everyone is lucky enough to be in a good position to have a pet. I know I could never find the time to take care of one. If you’re still in this boat but feel your home could use a little more movement, then why not try your hand at making a robo-pet?

Headless Cat

Designer : JohnThinger

If you’re newer to the sophisticated wiring that most kinds of advanced robotic pets will need, then you can always practice with the simpler models like this headless cat , a fun project that uses motors and gears ( which you can also 3D print ) to move around.

Articulated Robot Cat

Designer : ittonru

If that’s a little too basic, I found this robot cat with multiple points of automatic articulation to be strangely adorable, and I’m not even much of a cat person.

The details of this cat’s design were so in-depth that the designer even discovered the importance of a cat’s tail while editing!

Arduino Quadruped Robot

Download : CGTrader
Designer : cengiztezel
Price : $15.00

Like the example above, robot dogs don’t often actually look like dogs.

This is because ‘robot dog’ is the name given to most quadrupedal robot designs like this one , regardless of whether or not they were supposed to look like dogs.

That’s not to say you can’t either create your own body and casing to look like a real (or real enough anyway) canine companion.

Download : Cults3D
Designer : K3AVD
Price : $1.22

This design looks very professional and pretty cute to match. The only downside is that it was made as a fairly simple and educational example of a robo-pet.

But that shouldn’t discourage those of you looking for a challenge though.

It can become a great 3D printed engineering project by making your own tweaks and, if you can, even coding in your own AI to make a truly functional robot pet.

The possibilities here are enormous.

Depending on your skill level and comfort with electronics and coding, you could over time create an actual, working robot companion with the kinds of features that make it an ideal project.

It’s not just pets that you can make either.

Designer : nwayland

3D printing projects for engineers robot arm

This robot arm with impressively balanced weight distribution and full articulation is an excellent project that’s both educational and fun to use. It will take a bit of doing, but you’ll have this thing passing you drinks or parts while you’re working in no time.

Of course, it’s not the most efficient of desktop helpers, but as a 3D printer engineering project, this robotic arm should satisfy that itch to make something as cool as it is complex. You can also help with this project’s development process by using the STL files here and improving the robotic arm to be more useful, dextrous, and multi-functional.

Drawing Machine

Designer : CYUL

projects for engineering students drawing machine

As well as robotic arms, you can also 3D print a drawing machine for a more creative spin on an engineering project. Similar in concept to CNC machines or laser cutters, the drawing machine can be programmed to follow a specific ‘route’ while holding a pen or pencil to draw any given image automatically.

A drawing machine makes for an excellent project for engineering students as it combines electronics, the 3D printing process, coding, and automation all in a single piece of mechanical machinery.

Ending on a personal favorite of mine, orreries have always been really cool to me, and there are some really cool models out there to 3D print, some are exceedingly complex while others are small and simple.

While orreries can be motorized, they don’t have to be.

This makes it a great 3D printer project for engineers who are either not comfortable with or are simply sick of working around electronics.

That is to say, orreries can be considered to represent mechanical engineering in its purest and possibly even most aesthetically pleasing form.

Small mechanical orreries are good starting points, like this work-in-progress mechanical orrery or this oddly cute example including to-scale models of our Earth, moon, and sun.

3D printed orrery model with a Sun, Earth, and Moon

Of course, these are miniature and easy to print, so won’t be much of a struggle for you engineers. For that, I recommend the coolest, multi-piece designs.

My absolute favorite is this mechanical planetarium that stands tall and is accurate in both size and distance between planets.

It’s even been designed so if built correctly, one full rotation of the planetarium is equivalent to exactly two weeks of time.

If you don’t have the time or space to accommodate something that complex, I also quite like this smaller, slightly less complicated planetarium that’s still accurately depicting our solar system but on a smaller scale.

A spaced themed 3D printed musical Orrery

As an honorary mention, I’d like to link to this music box orrery . I’ve not tried it out for myself, but the concept seems really cool, even if it only has the Earth.

What is the future of 3D printing in engineering?

3D printing has revolutionized many industries, including engineering. From fast and inexpensive prototyping for things like car parts and other mechanical inventions, to making 3D printed, fully functioning jet engine designs. 3D printing is opening many doors in the engineering world and will continue to play an important role well into the future.
