For end mills, depth must not exceed 10x tool diameter.

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 Material

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.

Material Options for Stereolithography (SLA) 3D Printing

Stereolithography (SLA), the technology used to produce them, supports the creation of plastic parts with tight tolerances, intricate geometries, and smooth surface finishes. And parts printed using SLA stand out because of their exceptional accuracy, resolution, and level of detail. One key advantage of SLA is its ability to achieve finishes that are both highly […]

Scaling Up: From 3D Printed Prototypes to Injection Mold-Ready Designs

Are you ready to scale up from 3D printing to injection molding? Then it’s time to tailor your part design for a process that uses metal tooling and has its own unique design requirements. This article begins with some injection molding basics and then explains how to optimize your part design to reduce tooling costs […]
