The Advantages and Drawbacks of 3D Print Post ProcessingĪs you can see, post-processing in 3D printing is an important step to enhance a part’s final characteristics and visual appeal. For instance, dyeing is more popular with processes based on polymer powder, whereas painting is more popular with parts created with FDM. The choice between painting and dyeing depends primarily on the printing medium used. If we now consider staining, the end result is adding color to the final product.

A part’s surface can be altered using various processes, either by adding or removing material. All techniques used to enhance appearance, such as smoothing, polishing, sandblasting, infiltration, or milling, fall under the first category. The categories of surface finishing and coloring are used to enhance the parts’ aesthetics.

For powder bonding or indirect metal 3D printing processes, a debinding and then sintering stage must be completed using a specialized oven. This step primarily relates to polymer parts for instance, “curing” machines for resin processes are specifically made to be used with a specific printer, as with Formlabs solutions. These might include heat resistance, traction, UV protection, strength, or thermal stability. This entails raising a part’s temperature to enhance its mechanical qualities. For instance, when powder sintering is involved, this is frequently a time-consuming step that extends the production schedule. The time required for this step will vary depending on the printing method used. Whether powder or resin, the aim is to eliminate all extra material. As the name implies, this includes all methods for cleaning our components, such as de-soldering, rinsing, brushing, blowing, etc. This introduction is one of several articles written about 3D print post processing to help readers better understand the various types of 3D printing post processing.

Thus, post processing is crucial when beginning a 3D printing project. Undoubtedly, an FDM part requires a different approach than a metal part. While some post processing methods can be applied to any 3D printing method, others depend on a particular technology. For instance, refining a surface or annealing a component to boost strength and improve resistance. In 3D printing, post processing is primarily used to enhance manufactured parts’ appearance and/or functional qualities. However, why is this step important in 3D printing? How are markets organized?Ĭontinue reading to learn the answers to these inquiries about post-processing. Any work done after the part has left the machine, such as cleaning, surface finishing, annealing, and even coloring, is called post processing.Įach 3D print post processing method has unique requirements and is as diverse as the manufacturing processes. In 3D printing, post processing is the term for any operation performed on a printed component or for any method used to improve the object. 3D Printing Post processing, however, is the process of altering the part itself after the 3D printer has finished its work. Naturally, there is the printing phase, but there is also the modeling phase, which is where any project begins. There are several additive manufacturing value chain steps before you get to the finished part.
