Tough Epoxy Overview

Tough Epoxy is best for parts that require high accuracy, precision and strength. Print individual components with the confidence that they will assemble perfectly due to the high precision of VCJ technology. VCJ technology allows you to print in both Tough Epoxy and Soft Elastic at the same time. Meaning you can print elastic parts in place directly on tough materials to eliminate the need for assembling.

Build Volumes

500 x 250 x 250mm (19.69 x 9.84 x 9.84in)

Lead Times

❮❮ Extended- 7 business days

Quality (Microns)

This number determines how thin each layer is. The smaller the micron count, the thinner the layer, this results in higher surface detail and better surface finishes.


⭐⭐ Standard Quality - 25 microns


Material prints as-is, no color options available. Material is naturally light grey in color.

Pro's of Tough Epoxy

When Tough Epoxy is a perfect material choice
  • Can capture details as small as 0.30mm with over 99% accuracy
  • Print walls as thin as 0.10mm
  • Prints without supports which makes this material great for small cavities or hard to reach places
  • Self-correcting layers means less failed prints and more accurate, precise models
  • Larger build volumes than MJF Nylon PA 12
  • Multi-material printing capabilities, eliminating the need for assembly

Con's of Tough Epoxy

When to seek other material options

  • Longer than usual lead times compared to other materials we offer
  • No custom color options available
  • Higher printing costs
  • Has a bit of gritty texture to its surface (similar to Nylon PA 12)
  • Requires sanding before it can be painting, due to surface texture
