Overview
3D printing, also known as additive manufacturing, is a process of producing three-dimensional objects from digital models to create tangible prototypes. It builds objects layer by layer, enabling complex geometries and rapid prototyping.
3D printing is full service. Patrons submit a ticket and include the design file(s) in .obj or .stl format created with a 3D modeling software such as Fusion360. Staff will verify the file and communicate any potential issues. If adjustments are needed, patrons will need to edit and resubmit the file by replying to the ticket email. To learn the basic software, visit the MakerLab How-to Guide page or request a consultation if you have more specific questions.
Completion time will depend on dimensions, complexity, and current demand for the machines. Please submit projects at least 1 week ahead of time. When the print is completed, patrons will be notified via email. Completed projects will be held for one week. After that, unclaimed items will be discarded.

Design Considerations
Wall Thickness
- Minimum recommended: ≥ 0.8 mm (2 perimeters with a 0.4 mm nozzle)
- Thin walls may not print properly or be structurally weak.
Overhangs & Bridging
- FDM can handle overhangs up to ~45° without support.
- Bridges work best under 10–20 mm.
- For more aggressive angles or long bridges, add supports or redesign with angles and arches.
Holes & Tolerances
- Holes often print slightly undersized due to material expansion.
- Compensate with +0.1 to +0.3 mm clearance.
- Post-processing (drilling, reaming) may be required for precise fits.
Tolerances for Assembly
- Allow 0.2 - 0.5 mm clearance between moving or mating parts.
- Test and iterate fit tolerances - especially for snap fits, sliding joints or gear meshing.
Support Considerations
- Avoid unnecessary supports by:
- Splitting parts into multiple prints
- Redesigning geometry with chamfers/fillets instead of overhangs
Threaded Parts & Inserts
- Use heat-set inserts or brass threaded inserts for strength.
- If printing threads, use coarse threads
Material Choice
- Choose materials based on part function:
- PLA: Easy to print, rigid, brittle
- PETG: Tough, semi-flexible, good for functional parts
- ABS: Strong but warps easily
- Nylon, PC, CF blends: Stronger but need tuned settings
Post-Processing Options
- Sanding
- Drilling
- Tapping
- Priming/Painting
