If you have a design problem in need of a 3D-printed solution, please fill submit the form below.

We will add your problem to our problem bank page and will contact you for more information as soon as it catches the eye of one of our student designers.

What makes a good 3D design problem bank problem?

The purpose of the Problem Bank is two-fold:

  1. To get solutions to problems, and
  2. To provide opportunities for students to learn design thinking and 3D modelling and printing skills.

An excellent Problem Bank problem:

Urgency and authenticity

  • meets a real need but is not urgent
  • requires a completely new invention, an upgrade on something that already exists, or a personalised version of something that already exists

Time constraints

  • does not have to be solved immediately
  • requires a short print time so that many iterations can be created and tested

Physical constraints (materials, size, etc.)

  • is solvable using a device made of plastic, or plastic attached to some other material
  • is solvable using a device that is smaller (and preferably much smaller) than 250mm x 210mm x 210mm
  • can be ultimately solved with a solution that requires small amounts of materials and energy


  • has a solution that can be designed using Tinkercad or Fusion 360
  • provides students with practice in many elements of 3D designing


  • involves deep collaborations in order to “find the problem”
  • provides clear opportunities for others (problem poster, fellow designers) to provide feedback
  • provides a usable solution for self or other


  • provokes a solution that is relatively simple to design
  • has true potential for success

Cycle of improvement

  • lends itself well to original prototyping with conventional materials (cardboard, duct tape, modelling clay, etc.)
  • lends itself well to simply printing a “slice” or the footprint of the item to check specs
  • allows “cycle of improvement” to play itself out many times
  • lends itself well to many improvements, refinements, iterations
