Additive Manufacturing and Post Processing – A synergetic relationship

In the world of Additive Manufacturing, 3D printing is usually the first thing that comes to mind. However there is something equally as important in AM, and that’s strong relationships with post processing vendors. Once a part has been 3D printed, they are often not complete for a customers proposed application. This is why we rely on a synergetic relationship with post processing services to help us provide a complete and finished product that meets the customers criteria. The most common post processing services utilized in the AM industry today are Post-Machining, HIP treatment, and Anodizing.

Our friends at Cascade Precision Inc, an Oregon based AS9100 and ISO9001 certified Post-Machining company help to post process parts that require further assistance before they are considered complete. Post-Machine shops utilize high precision CNC machines to either lath or mill a part to meet given parameters or tolerances.

When parts need their density increased, heat combined with pressure is applied to the material from all directions in a manufacturing process called HIP (Hot Isostatic Pressing). Argon is the most commonly used pressure medium. After optimal HIP treatment is applied to parts tensile strength can increase significantly based on the ductility desired by the customer.

When aiming to give a part a certain cosmetic look, customers rely on anodizing services. Anodizing hardens and coats parts to make them tougher and give them a specific color chosen by the customer. Anodizing can differ between soft and hard coating, soft coating provides a thin coating while hard coating provides a thicker coating to help prevent corrosion.

Looking to the future, the importance of maintaining a synergetic relationship with post processing services cannot be overlooked. This relationship is crucial to meet the dynamic demands of the AM industry. i3D is committed to establishing strong working relationships with post processing services in order to provide the best product possible to suite our customers needs.

I3DMFG Contributes To Industrial CT For Use In Additive Manufacturing

I3DMFG Contributes To Industrial CT For Use In Additive Manufacturing

I3DMFG has been mentioned in an article alongside Delphi Precision Imaging with regards to new part designs that would be impossible with traditional machining methods  and require new measurement tools.

Every day additively manufactured (AM) parts are being used in new applications as the industry rapidly matures. As additive parts become more economical for small productions runs and move beyond use solely in tooling and prototyping, the need to nondestructively inspect parts for quality increases as well.

“Industrial CT is an excellent inspection method for additive parts and components from the automotive, medical implant and aerospace industries where quality and a high degree of reliability are critical,” says Blake Chenevert, president of Delphi Precision Imaging. Computed tomography (CT) has some advantages over other nondestructive inspection methods for additive manufacturing.

There are a lot of challenges currently facing the Additive Manufacturing industry such as defects, parts coming out as intended, yields, and cost/benefits. The article addresses each of these topics head on and in the area of Quality Control Inspection, I3DMFG had this to say,

“As quality requirements evolve inside of a disruptive industry like additive manufacturing, finding tools and innovative approaches to using those tools to advance nondestructive testing methodology is critical,” says Erin Stone, president of I3D MFG, a DLMS printer.

The article continues on to discuss the many areas of quality control and I3D MFG is leading the way to help shape many of these standards as well as creating many of their own which are being recognized industry-wide.

Reimagining Rocket Engine Design With 3D Printing

A UK Software company, Betatype, is pushing engineers to rethink and reimagine rocket engine design using 3D metal printing, or additive manufacturing.

The most recent example comes from a Betatype engineer, Marten Jurg, who has applied this philosophy while working on his postdoctorate degree.

Here’s exactly how they are pushing the boundaries of 3D printing:

  • They have successfully deployed an open file format called Arch which simplifies the handling of complicated CAD files
  • Engine processes an object for production in a powder bed fusion system.
  • Pilot assesses the optimal movements of a laser to produce fine details

Together, these components have allowed Jurg to integrate a fine lattice into the wall of an engine’s shell, resulting in an even cooling of the engine and its contents, typically fueled by liquid hydrogen that must be stored at −252.882 °C (−423.188 °F).

These “optimized” features of Betatype’s platform have enabled the engineers to create a sample of a scaled-down rocket engine printed in Stainless Steel 316L on an EOS M280 machine. Using a bigger machine, another company called AMAERO has taken Betatype’s platform and created an even larger version, bringing it to near operational capacity.

Betatype says this on their company blog,
