3D Printing

The slides for our 3D Printing workshop from MadLat 2016. In the workshop educators were exposed to various tools for creating content on the 3D Printer and some were even able to print their creations.

Transcript

1. Bit Space Development 3D Printing
2. 3D Printing allows you to create a physical object from your computer
3. What is 3D Printing? Imagine you could take a 3D object from your computer, size it, and print a physical copy. Would you download a car? Well you can actually do this. 3D Printing (additive manufacturing) is the process of creating a real object using a robot from your computer.
4. But Technology Is New And Scary! 3D Printing has been around for quite a long time in labs and for commercial use. It is only recently that we are able to build a home 3D Printer. Although some of the kit printers and open source options look new and scary, the commercial home printers like the Makerbot are quite safe for your kids and furry friends to be around. You probably won’t hurt yourself (maybe a little).
5. The Basics
6. Types Of 3D Printers There are several types of 3D Printers: • Stereolithography(SLA) • Digital Light Processing(DLP) • Fused deposition modeling (FDM) • Selective Laser Sintering (SLS) • Selective laser melting (SLM) • Electronic Beam Melting (EBM)
7. Fused deposition modeling (FDM) The most common type of 3D Printers. Adding layer after layer of melted plastic until you have a physical object
8. Fused deposition modeling (FDM) We have several printers here in the room, all of which are FDM printers. All 3 of them use the same types of plastic. The printers present are: 1. Makerbot Replicator 2 a. Commercial printer, expensive, closed source 2. Printrbot 1405 (kit) a. Open source, cheap, upgradeable 3. Prusa i3 a. Open source, cheap, upgradeable All of the printers here are easy to learn with and use inexpensive materials so you don’t have to invest in ultra high quality materials.
9. PLA vs ABS The 2 most common printer filaments.
10. PLA vs ABS ABS - The original king of 3D printing. It is hard and durable, curls easily when printing and smells terrible while you print your object. It is also not great to breath in so you need to make sure you have proper ventilation. PLA - Recommended for new users. A lot easier to print with. Does not require a heated bed for printing and is a lot safer to breath. PLA is actually compostable so not great for outdoor use but also if you drop it in a field it will dissolve over time.
11. Other Material Types • Nylon • Fillaflex (flexible) • Wood Core • Bamboo • Bronze • Carbon Fiber Depending on the quality of your printer you can use many different kinds of materials in your print. Wood filament is a good place to start.
12. Software
13. Free Software 1. Makerbot Desktop - Closed source a. Only useful if you have a makerbot 3D printer b. Does not work on older open source makerbots 2. Cura Engine - Open Source a. Developed for the Utilimaker printer b. Works great for most printers c. Built into Octoprint 3. Replicator Host - Open Source a. Works great for most printers b. Available for Mac and Windows c. Actually works 4. ReplicatorG, Pronterface, etc - Open source, some are outdated
14. Octoprint Have a Raspberry Pi? Octoprint can run on most computers, it is a web based controller software that can use Cura engine directly on the computer to slice and print the files you send it on a connected device. The Raspberry Pi has an image called Octopi that you can install and connect to your printer. You don’t need to have a computer tethered to the printer 24/7 anymore.
16. Design Tools • 3D Modeling Software ◦ Maya ◦ Blender ◦ Anything that can create an STL file • CAD software ◦ Tinker CAD (best, free, web based) ◦ 123D CAD ◦ Auto CAD ◦ Any CAD software, generate an STL file • Apps ◦ Autodesk 3D printing apps ◦ Morphie design (free, great for kids)

20. I’m Done Now What Now that you’re done your model, show it off to the rest of the group. We should see what we are creating. If it isn’t too big we can even print it on one of the printers in the class. It takes a little while to print so if you really want your object after the workshop you can reach us directly by email or order the print off 3D Hubs: https://www.3dhubs.com/winnipeg/hubs/daniel You can also take your file to a maker at Assentworks or your local library may have a printer available to you (the more you know).
