Metal Additive Manufacturing System Increases Build Speeds
IMTS 2016 Technology Preview
SLM Solutions features its SLM 280HL metal additive manufacturing system, a mid-range machine with a build envelope measuring 280 × 280 × 350 mm, at IMTS 2016.
SLM Solutions NA will feature its SLM 280HL metal additive manufacturing system, a mid-range machine with a build envelope measuring 280 × 280 × 350 mm, at IMTS 2016. The machine features a bi-directional re-coater blade to fresh powder on the build plate in both directions and reduce build times. Multiple laser configurations, including twin 400-W lasers or dual lasers of 400 and 1000 W, are also said to increase build speeds.
The machine uses inert gas handling to minimize the risk of operator exposure to metal powders and promote top material quality. The company provides open system architecture for materials and parameters, enabling machines to operate in-house with standard or individualized parameters. Individual developments on the machine can be transferred to other machines, such as the larger SLM 500HL platform.
GE Additive’s Ehteshami says, “To make these parts the ordinary way, you typically need 10 to 15 suppliers, you have tolerances, you have nuts, bolts, welds and braces.” With additive, “all of that went away.” The helicopter project is a detail in a story worth knowing.
3D printing requires different finishing considerations than traditional manufacturing. One expert offers do’s and don’ts for approaching the finishing of additively manufactured parts.
High-end metal additive manufacturing relies on the perfect gas composition to create products that meet the required material properties. But gas such as argon is also key to metal powder production, storage and postprocessing.
