Engineering Fit: Optimising Design for Functional 3D Printed Assemblies
Tolerance and fit are essential concepts that mechanical
engineers use to optimise the functionality of assemblies and production
costs.. For 3D printed assemblies specifically, designing for proper
tolerance and fit lowers post processing time and ease of assembly, also
reducing the material cost of iteration.
Use this white paper as a resource for designing functional 3D printed assemblies, or as a starting point when designing the fit between parts printed in Formlabs Tough or Formlabs Durable resins. This whitepaper will provide more information on:
The value of tolerances in 3D printing
The categories and types of engineering fit
Specific recommended design tolerances for Formlabs Tough and Formlabs Durable resins
The coefficient of friction for Formlabs Tough and Formlabs Durable resins are also measured, which can be helpful for designing sliding or kinematic solutions.
What you will learn
Design functional 3D printed assemblies that work as intended, with the least amount of post processing or trial and error. You will learn:
How to choose the appropriate fit (clearance, transition, or interference) for different types of functional 3D printed assemblies
When to use Tough or Durable resins for different fits and assembly applications
Recommendations for lubricants, bonded components, and machining
This white paper also includes downloadable test 3D models
that allow you to repeat our tests and determine design tolerances for other
3D printed materials.
