3D Print Requests

Policy Regarding 3D printing

All 3D print requests must be submitted through the queue using the link below. Users must follow the policy in the Baxter Innovation Lab User agreement, which prohibits project that are:

  • Those prohibited by local, state, or federal law
  • Those that are unsafe, harmful, dangerous or pose a threat to the well-being of others including but not limited to weapons.
  • Projects that contribute to a hostile academic or work environment, including those considered sexually explicit or otherwise offensive in the sole discretion of CLC
  • Project that are in violation of another’s intellectual property rights
  • Projects intended to be sold for profit (prototypes are fine)

Submit a Print Request

CLC students and authorized members can submit print jobs to the lab. Please note users are limited to 0.5 kg per academic year. If your total exceeds this amount, you'll be asked to fund your account to add additional filament credits.

Recommended Design Settings

  • Minimum wall thickness: ≥1.5 mm
  • Stress perpendicular to print layers
  • Use steeper and shorter overhangs, and fewer overall if possible
  • Minimize plastic for printing
  • Shorter bridges

Default Printer Settings

  • PLA 1.75 mm Diameter Filament
  • 0.2 mm Print Layer Resolution
  • Maximum Build Size: (x,y,z) 255 mm x 150 mm x 170 mm
  • Single Extruder
  • 230°C Print Temperature
  • 0.4 mm Nozzle Diameter
  • File Extension: .stl (note your unit type)
  • Infill 20%-30% (some applications may require more or less infill)

Avoid Shallow/Long Overhangs

Troubleshooting

Dimensional Changes from CAD model to Printed Part: Plastic expands and contracts as it is heated and cooled, and this thermal expansion/contraction causes dimensional variation in parts. Dimensional variation is also caused by the discrete nature of filament deposition, with the thickness of each layer corresponding to the diameter of the extrusion nozzle. To create dimensional accurate parts, adjustments must be made to CAD models. Outer features expand and inner features shrink as shown in the pictures below.
