and NickelAlloy IN625 can produce complex geometries unachievable with conventional manufacturing methods. Equipped with a 400-W fiber laser, the EOS M 290 has a build envelope of 250 x 250 x 325 mm. AM250 from Renishaw: Renishaw describes the AM250 as its flagship additive manufacturing machine. It includes an external powder hopper with valve in-
terlocks to permit additional material to be added while a process is running. Renishaw said on its website that multiple materials “can be interchanged on the AM250 platform with relative ease.” A variety of titanium, nickel,
stainless steel and cobalt chrome alloys can be used with the AM250. It has a build volume of 250 x 250 x 300 mm.
LENS 850-R from
Optomec: The machine comes with a “hermetically sealed Class 1 laser enclo- sure” and a five-axis CNC control system, according to the company’s website. Optomec said “core applica- tions” include component repair and hybrid manufac- turing, where both additive and traditional subtractive manufacturing can be done on the same machine. LENS 850-R can use metals such as titanium, tool steel, aluminum, nickel, cobalt and stainless steel. The machine’s work enve- lope is 900 x 1500 x 900 mm. The system uses a la- ser (500 W to 4 kW) to use powered metals into parts. A2X and Q10 from Ar-
cam: Arcam makes electron beam melting additive manu- facturing systems. The A2X is designed to
process titanium alloys and Inconel, “which makes it suited for both productions and materials R&D,” according to Arcam’s website. It has a build envelop of 200 x 200
50
x 380 mm. The A2X has beam power of 50–3000 W. The machine “is designed for production of any functional part within aerospace and general industry,” Arcam said on its website. The Q10 is designed for industrial output of orthopedic implants, according to the company. It replaces the Arcam A1 system. It has a maximum build size of 200 x 200 x 180 mm and maximum beam power of 3000 W.
