3D Printing

3D prints are limited to two hours during the day for both reservations and walk-ins. For print jobs over two hours, reserve the last evening slot for the 3D Printer and we can run the print past closing. Some exceptions can be made for prosthetics, community projects, etc. Ask us about how we can accommodate your project.

• STL or OBJ file

You can also download a file from:

• Your TinkerCad account
• Thingiverse
• or bring another file type of a 3D object you’ve made. (We can try to import it into a conversion program.)

In order to print a file, it must first be sliced by specific software for our machines. We use Cura. To preview your print or get an estimated print time, you can download the software for free. You are also welcome to use our MakerSpace computers to do this, and we'll be happy to assist you.

Sure! If you've never printed before and/or are unsure of the process, feel free to stop by the MakerSpace and speak with us about your project.

The MakerSpace uses PLA (Polylactic Acid) for 3D printing. PLA is a biodegradable plastic derived from corn starch or sugarcane.

3D printing at the Black & Veatch MakerSpace is currently free.

Print times depend on the size of your object, the detail/resolution of the project, how much infill is used (whether it's more hollow or more solid), and which printer is used.

Usually a project will be limited by time rather than size. The largest we can build something is:

• 11.7" x 10.8" x 9.8" on the Lulzbot Taz 5
• 6.30" x 6.30" x 7.09" on the Lulzbot Mini 2

There are many places to download 3D model files, some are free and some are available for purchase. You can download one on sites like:

• Thingiverse
• Sketchfab

You can also create a 3D file in a software called a 3D modeler. One of the easiest to use is TinkerCad, which is an web-based program that you can use on any computer with internet access. You simply create an account (safe for kids, too) and can store your files online.

If you're interested in more robust 3D modeling software, we have some options you can use in the MakerSpace:

• Blender
• Cura
• MoI 3d
• Rhino
• SketchUp Make
• Solidworks

Yes! We have a Structure Sensor 3d scanner available when reserving the MakerSpace PC. Scan large objects or scan yourself! Our 3d Scanner is not able to accurately scan small complex figurines and mechanical parts.

3D Hubs has an extremely thorough online guide. Another option is The 3d Printing Handbook, a beautifully illustrated technical book available for checkout at the Johnson County Library.
