Finishing Options for FDM and PolyJet 3D Printed Parts

22 1 Beginner
Finishing or secondary operations encompasses a broad range of processes that change a manufactured part’s properties. Engineers can employ finishing simply to improve part’s appearance and reshape it to meet certain dimensions, or use it to enhance functionality, such as increasing strength, chemical resistance, electrical conductivity and more. Secondary operations basically turn raw parts into finished goods and this isn’t limited to traditional manufactured parts. 3D printed parts can also be enhanced with secondary operations, but much like designing for additive manufacturing, different processes and best practices apply. Throughout the product design and manufacturing process, engineers should also be thinking about how 3D printed parts can be finished. Determining the appropriate finishing operations depends on the additive process, material and geometry as well as the desired aesthetics and functionality. This guide explains the primary finishing operations additive manufacturing service providers implement for FDM and PolyJet 3D printing technologies, grouped by possible finishing objectives, and compatible materials and applicable design considerations.

How to Solvent Smooth 3D Printed FDM Parts

12 1 Beginner
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.

How to Remove SUP706 Soluble Support on a 3D Printed Part

6 2 Intermediate
Removing SUP706 Soluble Support is quick and easy. Following the best practices ensures that you do not damage or break your part in the process. The following is brought to you by Stratasys.

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

6 1 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.

How to Paint FDM Parts

5 1 Intermediate
There are many reasons for coating FDM parts. These include UV protection, sealing, shielding, or surface modification, but painting FDM parts for an aesthetically pleasing finish is the most common. Painting brings a product to life by adding depth, contrast and character. This is true for concept models, marketing samples, and finished goods. For product development and many production applications, paint completes the desired look and feel. With a little know-how and a touch of patience, models, prototypes, and parts can look like production parts. The following instructions are for creating top-quality painted parts. For applications that do not require this level of finishing, skip any unneeded steps. A good paint finish traditionally starts with sanding and filling.

Creating Texturing Patterns on FDM Parts

3 0 Beginner
The goal of this tutorial it´s how to add texture patterns to your FDM part and make it more presentable. Erasing those awful visible layers to give a better finishing, you can salect any texture and add to your FDM parts even photos or any image.

How to media blast FDM parts

0 0 Intermediate
Common applications where media blasting is applicable: • Smoothing and polishing for: - Concept models - Prototypes - End-use parts • Surface preparation such as texturing and etching for: - Painting - Electroplating - Mold masters

Inserting Hardware Post-Build

0 0 Intermediate
Various types of hardware are commonly used in plastic parts to withstand the torque and load applied when joining parts to create assemblies. Like machined or molded plastics parts, components made with FDM technology can also have hardware inserted into them. Inserts may be added during an FDM build or in a secondary, post-build operation. This Best Practice covers secondary insertion of hardware with common methods such as adhesive bonding, pressing, and heat setting.
