Recycled Materials for Additive Manufacturing Technologies (ReMAT)
Purpose and goals
ReMAT aims to create a circular and sustainable pathway for 3D printing of high-strength steels, thereby supporting Sweden’s goal of achieving net-zero emissions by 2040 while strengthening industrial competitiveness.
Expected effects and result
By comparing recycled and reused powder with virgin material, ReMAT validates their performance through process optimization, material testing, and industrial demonstrators. Life cycle assessments quantify the environmental benefits. The outcome will be reduced waste, decreased dependence on virgin materials, and more climate-efficient, robust steel production in Sweden.
Planned approach and implementation
The project is based on two strategies: recycling steel scrap into high-quality powders for 3D printing and extending the lifespan of already used powders. Fine powder fractions are used in Metal Binder Jetting, mid-sized fractions in laser-based Powder Bed Fusion, and coarser fractions in Directed Energy Deposition for repairs—ensuring that all powder is utilized. Testing will show how powders change during reuse and provide guidelines for safe and effective use.
