Post-Processing

As additive manufacturing technologies experience greater use for batch, serial and mass part production, post-processing becomes increasingly relevant. Our main focus at 3dpbm is on digital additive part production—a market for which we have coined the acronym DAMP—so the need to produce fully finished parts and the enabling technologies to achieve this via AM have always represented a key area of interest.

One of the biggest hurdles to greater adoption of AM in production was always a tendency to underestimate the impact of cost-effectively post-process large series of prints. On unique, ultra-high-value parts such as prototypes and tools, post-processing is a relatively minor concern. But when it comes to post-process tens, hundreds and even thousands of parts in a few days, the challenges grow exponentially.

Producing fully finished parts presents significant challenges in the polymer AM market and it presents even bigger challenges in metal AM and ceramics AM. So much so that even metal PBF technologies, where part sintering/fusion takes place during the printing process, resulted more time-consuming in terms of their post-processing phase than binder jetting technologies, where debinding, infiltrations and sintering are all carried out as additional post-processes.

The segment for AM post-processes differs for each major technology but can be generally intended as including these main areas: Powder Removal and Sieving systems, Debinding and Sintering systems, Material and Parts Handling systems, Measurement and Inspection systems, Support Removal systems, and Thermal Treatment/UV Curing systems.

Today there is a much greater awareness of the various post processes that are required in all AM technologies, both through operators such as AM Solutions, PostProcess Technologies, AMT, Solukon and D-Lyte (among others) that focus specifically on automating AM and several other companies specializing in automated post-process solutions for injection molding and other traditional technologies now looking more closely at the AM market.

In this month’s AM Focus we will highlight many of these companies and their capabilities. For a full list of companies specializing in the various phases of pre- and post-processing AM solutions, make sure to visit the 3dpbm Index’s dedicated section on Automation and Post Process companies here.

  • DAMP, a new acronym to convey the evolution of AM into mass production

    We have grown accustomed to using the acronym AM to indicate additive manufacturing. In the past companies like Airbus have also used ALM (additive layer manufacturing). As additive manufacturing evolves into a technology used in direct, digital production of large series of parts, rather than one-offs, short batches, prototypes and…

  • Going with the AM-Flow

    Ever since 3D printers began the paradigmatic shift from stand-alone rapid prototyping machines to networked units within production workflows, it became clear that additive manufacturing—the most digital among manufacturing processes—was also the least automated and the hardest to integrate into full end-to-end production workflows. By comparison, injection molding—the least digital…
