Using the 3D Print Lab

Using the
3D Print Lab

1. DESIGN

All projects begin with a digital 3D model.

Learn how to create your own designs or find an existing model on websites like Thingiverse. You can even download an existing model and customize it. Create your own original design and move to the front of the waiting list!

Find links to free, easy-to-use 3D design software like TinkerCAD on our recommendations lists.
3D Print Lab volunteers are happy to answer any CAD questions you have.

2. TEST

Download Prusaslicer for free to see an estimate of print time and if your project will need extra support. Remember, using a 3D printer is like stacking bricks: you can't stack bricks on thin air. Any overhanging pieces will require extra supports. See print lab volunteers for assistance.

View your design layer-by-layer and identify structural issues in PrusaSlicer.
Select 'Mk3.9' or 'MINI' as your 3D printer model during setup.

3. PRINT

All projects must be submitted in person with a 3D Print Lab Volunteer. If you are printing an original design, please bring the file to the library on a flash drive. If you would like to print a file from Thingiverse, please bring the project number or URL from the website.

Projects submitted from Thingiverse must be inspected by a volunteer for approval

3D printers build objects by extruding material in thin layers,
stacking one on top of the other.

4. CLEANUP

Some print jobs require adding a brim (a thin layer of filament to stabilize the base) or other supports. These can be easily removed after printing.

Many print jobs will require light sanding or trimming in order to look their best.

Designs with lots of overhangs require lots of extra support!
Pliers and diagonal cutters are ideal tools for removing supports.

The 3D Print Lab is run entirely by volunteers, and availability is subject to change. If you are interested in submitting a project, you can call ahead at (916) 358-3500 to see if the print lab is open. Only 3D Print Lab volunteers may operate printers.
