3D Printing at the Innovation Space

How-To Guide for 3D Printing

3D Printers at HS/HSL

Lulzbot Taz 5, MakerBot Replicator 2X and Afinia H480 are available. All three of them utilize the Fused deposition modeling method,


3D Printer Models

Maximum Build Size & Resolution

Each 3D printer has a different maximum size 3D model that it can print. They also have different resolutions, which determine the level of details of the 3D model.

  • Lulzbot Taz 5
    (Maximum Build Size: 290mm x 275mm x 250mm (11.4in x 10.8in x 9.8in); Layer Thickness with 0.5mm nozzle: 0.075mm to 0.5mm (0.003in - 0.0196in))
  • MakerBot Replicator 2X
    (Maximum Build Size: 24.6 L x 15.2 W x 15.5 H cm; Resolution: 100 micron/0.1 millimeter)
  • Afinia H480
    (Maximum Build Size: 140 x 140 x135 mm; Resolution: 0.15-0.40 mm vertically)

Printing Time

  • Most 3D printing jobs take longer than people expect.
  • From two to more than twelve hours depending on the size, complexity, and density of your model and the settings such as the printer speed and the infill ratio.
  • Many 3D print jobs fail due to a variety of reasons from design defects involving non-manifold geometry in a 3D model to technical problems with a 3D printer.
  • More time is required if those design defects need to be corrected and the print job has to be repeated.
  • Before repeating a failed print job, you may need to troubleshoot. This may add additional time until you get a successfully printed 3D model.

Software & File Type Compatible

Each 3D printer takes in a 3D model file (.STL). The proprietary driver application for each 3D printer slices the 3D model and creates g-codes, which tell the 3D printer which printer settings to use and where to position its printer heads for printing. For example, 3D model files in .X3G contains only those g-codes in the binary format.
