3D Printing Parts Manufacturer China

Product Details: NICE Rapid Tooling offers FDM (Fused Deposition Modeling) 3D printing services. FDM is a melting deposition molding process developed by American scholar Scott Crump in 1988. It involves melting material into a liquid state, extruding it through a print head, and then solidifying it to form solid objects. The FDM mechanical system consists of a sprinkler head, wire feeding mechanism, motion mechanism, heating studio, and working table. This technology can print with various materials, including composite engineering plastics, nylon plastics, ABS, and PLA. The process affects the printing accuracy due to factors like infill and layer thickness, and temperature of

the nozzle. Post-treatment such as sanding and polishing is often required for a smooth surface finish.

How To 3D Print Assemblies With Moving Parts

Product Details: The blog post discusses 3D printing assemblies with moving parts using two different 3D printing technologies: Fused Deposition Modeling (FDM) and PolyJet Technology. The project involved designing a six-part 3D printed bracelet with paraboloid joints and a fold-over clasp sliding mechanism. The bracelet was printed on both a uPrint SE Plus (FDM) and an Objet500 Connex3 (PolyJet). Key considerations included clasp design, joint type, and the removal of support material. The design avoided long through-pins and ensured adequate clearance between parts to prevent fusing and facilitate support material removal.

Pros:
– Ability to quickly prototype complex and intricate assembled parts in a single b…
– Higher resolution of PolyJet Technology allows for tighter clearances and smooth…
– FDM version showed better durability and longevity of the fold-over clasp mechan…
– Efficient design and printing process that minimizes the need for traditional pr…

Cons:
– Support material removal was more labor-intensive for PolyJet prints, requiring…
– Softer material used in PolyJet prints showed light signs of wear after repeated…
– FDM prints may not achieve the same level of smoothness and tight clearances as…
