Baxter Innovation Lab
Promoting hands-on design and innovation for students, teachers and professionals.

Project Requests

CLC students and other authorized users can submit projects to the lab. Clients may submit projects they wish the lab to complete or those they would like assistance with. Project requests may include design, fabrication, prototyping, or one-offs. Projects are viewed as learning opportunities for students and the lab's engineering interns. The capacity to deliver on project requests depends on the availability of students and/or interns to work on it. Clients should not expect or rely on a short turnaround, given the learning-centered nature of the lab. The following equipment can be requested:

  • 3D printing
  • laser cutting  and etching
  • CNC milling (Roland MDX 40)
  • CNC routing (Shopbot)

You can also request a consultation if you're not sure what type of equipment would be best suited for your project. Information about the equipment available in the lab can be found on the Equipment page of this website.

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)

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

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.
