3D printing replacing steel

Eba sp. z o.o., based in Krosno, specializes in metal processing and production of all kinds of metal parts. It is constantly developing its production capabilities, the specialists use 3D printing technology to produce machine elements and smaller spare parts. In order to test the capabilities of the industrial printer and the durability of the printed final elements, Eba asked us to print a part that would replace the metal original. Omni3D technologists faced the challenge of 3D printing a sheet metal bending knife, which was supposed to match the properties of the original part.

Case-study 

The sheet metal bending tool used in daily metalworking consists of consists of two parts: a knife and a mold made of tool steel as standard. It is an element which is subject to high durability tests and is exposed to abrasion. Our task was to print the element selected by Eba, which was to replace the existing tool. CF PA-12 material was chosen for this project. It is a polyamide 12 (PA 12) composite material, enhanced with carbon fibers. It is characterized by exceptional durability, high stiffness and tear strength.

Solution 

Due to the unusual shape, long waiting time for production by traditional methods and cost – 3D printing proved to be the best solution. It is an alternative for creating spare parts and producing necessary components. The bending knife was printed on our Factory 2.0 NET industrial 3D printer.

Effect 

3D printing technology using CF PA-12 material with carbon fiber proved to be the best solution. 3D print positively passed the customer tests and guaranteed the required strength! Most importantly, the technology shortened the lead time from 4 weeks to 1 day and reduced production costs!
