Additive Manufacturing

Selective Laser Sintering


Selective Laser Sintering is a powder bed fusion process where thermal energy (e.g. laser) selectively fuses regions of a powder bed.

  • Type: DTM Sinterstation 2500
  • Material: PA12 (Recyclable)
  • Build envelope of 13 x 11 x 16.5 inches (381 x 350 x 457mm) with nitrogen atmosphere
  • Scan Speed: 5m/s
  • Laser power: 100 Watts (CO2 laser)
  • Layer thickness range: 0.004 – 0.02 inches (0.1016-0.508mm)

Printing prototypes in the Selective Laser Sintering machine is available for students and faculty at the University of Wisconsin-Madison. For more information, follow the link below.

Fused Filament Fabrication (FFF)

Fused Filament Fabrication is an additive manufacturing process in which material is selectively dispensed through a nozzle or orifice. At PEC, several FFF 3D printers are available for educational and research purposes.

SciSlice - Customized ToolPathing


SciSlice is a program that creates custom tool paths for Fused Filament Fabrication 3D printers (also known as FDM™). The motivation for creating this program was to allow the user to independently adjust as many printing parameters as possible for the purpose of researching and characterizing each parameter's effect on a part's properties. These printing parameters can be changed between layers and even within sub-regions of a layer.

More detailed information and application of the SciSlice can be found on GitHub. Learn more.
