Mitsubishi Chemical Corporation (MCC), announced that it has entered into an exclusive joint development and commercial partnership agreement with AM Polymers GmbH (AMP), a German new materials start-up company, to develop polybutylene terephthalate (PBT) powder products for industrial 3D printing, similar to what poly chemistry produces..

AM Polymers specializes in producing and selling thermoplastic powders with “Plug & Play” processability and part performance for selective laser sintering (SLS) and powder bed fusion (PBF) processes. Through this partnership, both parties are jointly developing new powder products for industrial 3D printing from PBT feedstock, specially optimized based on MCC’s chemical expertise. A beta version of ROLASERIT® PBT01 powder will be soon unveiled in Europe for client evaluation.

AM POLYMERS GmbH

Founded in 2014 as AM Polymer Research UG as a spin-off of the University of Duisburg-Essen, the company has had a successful start. AM POLYMERS GmbH (AMP) produces and sells qualified plastic powders for industrial 3D printing. They manufacture traditional plastics that are standardized and well known in injection moulding and therefore essential for additive production. 

AM POLYMERS also offers research and development services for partners such as BMW AG, Deutsche Bahn AG, Daimler AG and Siemens AG in order, for example, to qualify additive manufacturing processes for series application or to develop customer specific materials.

Polybutylene terephthalate (PBT) is an important thermoplastic material that offers high-strength & high heat resistance. Therefore it is widely used in electrical insulation applications. It can resist heat up to 150 OC. It is also solvent resistant and is mechanically strong.

The PBT powder enables additive manufacturing engineers to create lightweight components for electrical components, automotive motors and bathroom furnishings. 

This partnership provides Mitsubishi Chemical Corporation and AM POLYMERS, an opportunity to further expand their product portfolio for 3D printing. SLS/PBF is a process by which users can achieve complex geometries at short production lead time. Coupled with good mechanical properties, PBT powder has much lower moisture absorption characteristics than polyamide 12, a common material for SLS/PBF. Thus, MCC and AMP expect new PBT powder products to be used for industrial 3D printing applications such as automotive and aerospace. This new partnership enables MCC and AMP to further accelerate growth in the 3D printing area.
