Engineering Fit: Optimizing for Functional 3D Printed Assemblies

Why You Should Download

Engineers use tolerance and fit as important attributes to optimize the functionality of mechanical assemblies and lower cost of production. 3D printing helps to lower post-processing time and ease of assembly while reducing material costs from multiple iterations.

Design functional 3D printed assemblies that work as intended, with the least amount of post-processing or trial-and-error. This white paper includes:

  • 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

  • Downloadable test models that allow you to repeat our tests and determine design tolerances for other 3D printed materials

Best practices in this white paper can help users 3D print functional assemblies with the least amount of post-processing or trial-and-error.

What you will learn

  • The value of tolerances in 3D printing
  • The categories and types of engineering fit
  • Recommended design tolerances for Formlabs Tough & Durable resins

Download this white paper to use as a guide when designing the fit between parts and assemblies. The coefficient of friction for Tough and Durable are also measured, which can be helpful for designing sliding or kinematic solutions.
