Abstract

3D printing, also known as Additive manufacturing and rapid prototyping in the pasts has been growing exponentially in reset years. While plastic 3D printing is widely used, 3D metal printing has limited applications due to several factors. To make functional metal parts, the technology needs to be tested and compared with existing metal fabrication technology. We will discuss testing the physical, mechanical, and metallurgical properties of the parts produced with the Hybrid 3D metal printer. Our printer uses GMAW welding and CNC machining, two widely used methods in industry-developed to a novel hybrid system that can produce a part in one setup. We did our testing following the regulation by ASTM and ISO 3D printing standards and NIST Additive Manufacturing Benchmark Test Series (AM-Bench). We used standard methods to evaluate tensile and bending strength, hardness test, micrograph with optical and microscale laser microscopes, surface rouges, CT X-ray scan, and laser and white light 3D scanning. The result proved that our technology can produce parts with mechanical properties exceeding the standard wrought metal products.
