Furnaces For Metal 3d Printing Processes and Additive Manufacturing

CM Furnaces is on the cutting edge of commercial additive manufacturing of metal parts, owing to its long history providing furnaces for the sintering and annealing of traditional MIM parts for production. In the world of 3d printing, small volume, low throughput applications like dental implants and jet engine parts are well known and good fits for what was traditionally a low throughput or one-off type production environment. Fast forward to 2017 however, where costs of purchasing and deploying 3d production lines is coming down while maturing 3d printer capabilities show that manufacturing lines can achieve mid to high volumes of throughput bringing them into the realm of more and more mainstream production requirements.

In particular, 3d metal printing manufacturers, have found the CM Rapid-Temp line of box and tube furnaces to be a perfect fit for the finishing of metal parts in almost all materials currently used.  As throughput increases however, continuous or pusher furnaces made by CM, also find a place in high volume 3d printed part production, achieving the same atmosphere capabilities and multi-stage thermal control long enjoyed by MIM and other sophisticated metal forming applications.

Specialized Thermal Finishing For 3d Metal Printing – Batch Furnaces

Commercial metal parts can be printed from aluminum, stainless steel, brass, copper, bronze, sterling silver, gold, platinum, titanium not to mention hybrid ceramic compounds.  Typical processes used achieve a wide variety of results for finished parts including sintering, debinding, fusing, curing, heat treatment and more.  Another key consideration is the ability to support a wide variety of atmosphere’s such as hydrogen, argon, or other inert gases to facilitate processing.

And key to your ability to reliably reproduce acceptable 3d printed metal parts, is your ability to carefully and safely control heat and soak times in the proper atmosphere, while achieving accurately the high temperatures needed for a wide variety of processes. Perhaps one of the most unique features of the CM line of furnaces is their extended temperature operation vs. their low cost of ownership: a direct relationship to the high quality of parts and materials used in all our USA made furnaces.

Overview of CM Furnaces Suitable For Finishing of 3D metal Printed Parts

Rapid Temp Series – 3d Metal Printing Batch Finishing Furnaces

As their name indicates, extremely fast thermal cycling is possible owing to the use of ultra-high quality Kanthal heating elements. Rapid Temp furnaces used in the post processing of 3d printed metal come in several different series according to their maximum temperature range. All furnaces have options to run a completely sealed atmosphere with advanced safety controls.

Rapid Temp Series Furnaces for Calcining, Sintering

Advanced engineering techniques include high purity alumina fiber insulation, stainless steel double wall shells, and long-life Kanthal heating elements with extremely high uniformity. Configurations are available for virtually any requirement with three basic configurations including front loading, bottom loading and front loading atmosphere retort in a variety of chamber sizes.
