5. 3D Scanning and Printing

About this week

Briefly describe the goal of the assignment. What are you characterizing, testing, or exploring

Ger:

  1. Testing print-in-place parts, with various tests for axial strength tests etc., on the UltiMaker S5.
  2. Testing properties of large-format 3d-printing.

1.: Printed-in-Place part was Acrylic insterted during a printer pause. Tested “Squiggle” bending, stretching and torsion; Print in place handles, and, for comparison, all-PLA part.

2.: Using the Ginger G1 pellet printer, with a nozzle size of 3.0mm. Did the Overhang Angle Test and the Bridging Test.

Tools and materials used

List all the machines, software and materials used in this assigment.

Ger: Tools and Materials

  • Laptop,
  • UltiMaker S5
    • FormFutura PLA (2.85mm)
  • Ginger G1 system
    • rPLA Pellets
  • Measuring devices

Process and methodology

Describe step-by-step what the group did. Include sketches, screenshots, or videos if possible.

Ger:

  • Drew in Rhino3D, and went from Rhino to DXF for laser cutter part.
    • Tolerance (height) was too low. Measured acrylic thickness was 3.1mm, and layer-height of 0.15mm. Increased by one layer. Caused “Filament-Stuck” error when too low.
    • Rewrote to Grasshopper to test series of dimensions. And re-wrote for all PLA part.
  • Printed the 3DHubs on the G1. Scaled x2.4.
  • Observed top surface issues on other models. Due to the size, top surfaces drag between infill gaps.
    • Wrote a grasshopper script to test bridges without volumes (series of wall contours)
