Показать описание

Every aspect of the additive process can impact the end-state material properties. Primary variables a materials engineer must consider are listed below.

⚪ 𝗠𝗲𝘁𝗮𝗹 𝗣𝗼𝘄𝗱𝗲𝗿 𝗖𝗵𝗮𝗿𝗮𝗰𝘁𝗲𝗿𝗶𝘀𝘁𝗶𝗰𝘀: Powder characteristics such as particle size and shape will affect how the powder is distributed in the print bed.

⚪ 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗛𝗮𝗿𝗱𝘄𝗮𝗿𝗲 𝗮𝗻𝗱 𝗣𝗿𝗼𝗰𝗲𝘀𝘀 𝗦𝗲𝘁𝘁𝗶𝗻𝗴𝘀: Machine parameter settings such as beam power and shape, layer thickness, and gas flow all have different impacts on the resulting bulk material and surface quality

⚪ 𝗣𝗮𝗿𝘁 𝗚𝗲𝗼𝗺𝗲𝘁𝗿𝘆, 𝗧𝗵𝗲𝗿𝗺𝗮𝗹 𝗣𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴 𝗮𝗻𝗱 𝗦𝘂𝗿𝗳𝗮𝗰𝗲 𝗧𝗿𝗲𝗮𝘁𝗺𝗲𝗻𝘁𝘀: Part features and surface conditions can impact localized material behavior, while thermal processing affects the bulk microstructure and can be tailored to achieve certain material properties.
