ABS

ABS is a plastic material that's great for mechanical strength and early stage rough prototypes. ABS is a cost-effective material for initial prototyping applications, and with post-processing options it can offer better surface finish than PLA.

Additional Design for Manufacturing Tips

  • No internal cavities
  • Limit curved surfaces, especially for PLA and PET-G as they require a flat surface to result in a successful print
  • Orientation on small holes is very important (xy plane is much more cylindrical)
  • Bridging: distances of up to 10 mm do not necessarily need support material, as long as the area being printed has support on both sides of the material being laid down.

Cost Saving Tips

  • Cut large models into multiple smaller parts, to fit on a smaller, less expensive machines.
  • Reduce the amount of support material required by overhangs and special orientations.
  • Choose PLA for simple geometry parts and where tolerance is less important.

About the Process

Fused deposition modeling (FDM) is a 3D printing technology (also known as additive manufacturing) commonly used for modeling, prototyping, and production applications. Each layer is created by extruding material from a nozzle to produce 3D objects.

FDM processes require support material, either breakaway or soluble, so it’s important to keep this in mind when choosing this process as it can affect the final part.
