How to Give Your 3D Printed FDM Part the Smoothness of Injection Molding

3 3 Intermediate
This tutorial will demonstrate how you can give your FDM printed part the finishing smoothness of injection molding. The Finishing Touch Smoothing Station can dramatically improve the surface finish of ABS parts that are built using FDM technology. The semi-automated smoothing process is compatible with FDM’s entire line of ABS plastics. The following is brought to you by Stratasys.

How to Solvent Smooth FDM Parts

1 0 Expert
The normal surface finish of FDM parts is suitable for most purposes, but in applications where a smoother surface is required, solvent smoothing is an alternative to sanding, filling, and mass finishing. Solvent smoothing utilizes a chemical agent to smooth a part’s surfaces (Figure 1). This process modifies the surface of FDM parts by eliminating layer lines while preserving feature detail and part accuracy. The smoothing agent can be applied either as a liquid or a vapor and it is quick and nearly labor-free. The finish achieved can mimic that of injection molded parts.

FEA Results in Color 3D Printing

1 0 Intermediate
Finite element analysis (FEA) is a computer-based method of analyzing and simulating the behavior of components under a variety of conditions, including force, temperature, vibration, and motion. FEA calculates displacements, strains, and stresses under internal and external loads. These predictions confirm if a design is suitable or if modifications are required to prevent failure.

How To Dry Sparse FDM Parts

0 0 Intermediate
When sparse FDM parts are placed into a support removal tank, they can fill up with solution from the tank and water from the rinse. Most of this solution or water will drain from parts naturally within 30 minutes of their removal from the tank. However, in some cases, geometry will trap some liquid inside. Later, this liquid will slowly leach out. To avoid this, we recommend using a vacuum and/or oven to completely remove any liquid from your FDM parts. The best method is to use the vacuum first, followed by the oven. Either method can be effective individually if you increase the amount of time the part is in the oven or the number of vacuum cycles applied to the part.
