3D Printers

How to Use the 3D Printers

Demo

There are several steps when creating a finished 3D printed product at the makerspace: 1. Create or find a 3D model – Design in Fusion 360, SolidWorks, TinkerCAD, or FreeCAD, or download from Thingiverse, MakerWorld, Printables, or MyMiniFactory. 2. Slice your model – Convert .stl, .3mf, or .obj into .gcode using Bambu Studio, PrusaSlicer, Cura, or Chitubox. 3. Send to printer – Transfer G-code via SD card, USB, or network (for Bambu printers). 4. Monitor the print – Ensure first-layer adhesion and proper extrusion or resin exposure. 5. Post-process – Remove supports, clean the area, and finish your model. 6. Weigh and Pay – $0.05/g for FDM, $0.10/g for SLA prints using makerspace materials.

FDM / Extrusion Printers

Fused Deposition Modeling (FDM) — also known as Fused Filament Fabrication (FFF) — is the most common form of 3D printing.
These machines melt thermoplastic filament and deposit it layer by layer to form a solid object.
At the makerspace, we use FDM printers for durable parts, enclosures, and mechanical prototypes.
All FDM prints using makerspace filament are priced at $0.05 per gram.

SLA / Resin Printers

Stereolithography (SLA) and Masked SLA (MSLA) printers use UV light to cure liquid resin one layer at a time,
producing parts with extremely fine detail and smooth surfaces.
At the makerspace, SLA printing is ideal for miniatures, molds, and detailed prototypes.
SLA prints using makerspace resin are priced at $0.10 per gram.

Friendly Printer Usage

• Share the printers: During high-usage hours, please use one printer at a time so everyone gets access.
• Be mindful of queue length: For long jobs (>8 hrs), consider off-peak times or split into smaller parts.
• Filament storage: Return open spools to sealed dry boxes after use.
• Vacuum-sealed spools: Store vacuum-sealed filament on the rack above the FDM printers. Do not open unless needed.
• Resin handling: Cap bottles, clean drips immediately, and keep resin in approved containers only.
• Weigh & pay fairly: Weigh all completed prints, including supports and failed prints, and pay:
  • FDM: $0.05/g (makerspace filament)
  • SLA: $0.10/g (makerspace resin)
• Cleanup is part of the job: Vacuum the floor around the printers, wipe the tables, and leave the area free of debris or resin spills.
• Log issues: If a printer misbehaves (clogs, layer shift, adhesion problems), note it on the printer log and send a message using Report a Problem
