User Question:
What are the differences between BJ technology and SLM technology?
1. Different Principles:
(1) SLM Technology: Uses a laser to directly melt metal powder, stacking layer by layer;
(2) BJ Technology: First sprays adhesive onto the metal powder, then sinters at high temperatures to solidify.
2. Part Performance:
(1) SLM Technology: Produces high-strength, high-performance metal parts, with strength close to that of forged parts;
(2) BJ Technology: Does not require support for printing, thus achieving better surface finish, and allows for faster mass printing of metal parts.
3. Applicable Scenarios:
(1) SLM Technology: Suitable for printing housings, sheet metal, and long structures that require high strength in metal parts;
(2) BJ Technology: Suitable for printing medium-sized metal parts with complex internal channels and high surface quality requirements, while avoiding printing easily deformable structures (such as sleeve parts, dumbbell shapes, and irregular shapes) and extremely small-sized structures.
