3D Printing

!!Please note, this printer is unavailable until Ken returns in March!!

UPrint 3D Printer (older one)

Support material is chipped away by hand and dissolved in chemical bath

Material: Acrylonitrile butadiene styrene (ABS) thermoplastic polymer

Support: (soluble and removable)

Process: Layered deposition (‘Resolution’ is the thickness of each layer.  smaller resolution = finer detail/slower build) from 2 print heads (Material and Support)

Tool and Build Specifications

Bed Volume: 6D x 8W x 6H IN

Minimum Thickness: 0.254 MM

Cost: $3 per cubic inch

Students can prepare .stl files in CAD software (tutorial link) and submit to Digital Printing Technician (Ken email) for printing.

Process Notes

  1. Due to the high cost of printing, students must acquire a price (from Digital Printing Technician) and pay first before printing.
  2. Consider the uniqueness, size, and replicability of your geometry.  A single simple box is not an appropriate use of the tool.
  3. For better results, scale the 3D model to fit the build volume before generating the STL file.
  4. Consider that the object will be built vertically.  Proper orientation (minimize support) will save time.  Also, the object will have a ‘grain’ parallel to the horizontal surface.
  5. For best results, build the 3D model within the dimensions of the build volume. After scaling a large 3D model to fit the size of the build volume, sometime part of the building structures may be too small to print, results in lost of support in some areas.
  6. Always test a smaller version first.
  7. TIME, TIME, TIME….in many occasions each print will take up to 24 hours.
  8. The machine has to be constantly checked at the beginning of a print job to ensure there is no lost of extraction of material.
  9. If you see there is something wrong, switch off the machine (on the back left) and contact Digital Printing Technician. DO NOT attempt to fix the machine.
  10. If the machine runs out of material during a print job (sometimes it happens in the middle of the night), DO NOT attempt to change the cartridge. Contact Digital Printing Technician the next morning.
  11. Files must be WATERTIGHT.  Think ‘Chocolate Bunny.’  No Naked Edges.

When it is finished printing….

This 3D printer consist of two types of material. Model (white) and Support (dark brown). After printing, you must dip the 3D print in a solution (beside the printer) to dissolve the support material. It is a good idea to chip out as much support material as possible before you dip it into the bath. This will prolong the longevity and the strength of the solution.

After the support material is dissolved, take the 3D model from the bath solution and wash it off over tap water.

ALWAYS WEAR SAFETY GLASSES AND RUBBER GLOVES WHILE CLEANING YOUR MODEL (You can find both items around the area of the printer)

Form 2 3D Printer (new one)

!!This section is still under review. Check back for updates once policies are decided!!

Before designing your model, refer to the Tech Specs and Design Specs on the Form 2 website.

Support: automatically generated in PreForm software, removed with tools

Process: model is built upside-down on the build platform. Each layer is formed by a laser solidifying the resin. 

Tool and Build Specifications

Build Volume: 5.7 x 5.7 x 6 inches

Cost: 30 cents/mL for regular resin, 40 cents/mL for flexible resin

Students can prepare .stl files in CAD software. Check the cost and time by opening in PreForm. Book time here, and co-ordinate with Carolyn or a TA to send for printing.
