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 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 necessary to achieve 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 different 3D printing technologies. Mechanical Engineer Alexei Samimi designed a six-part 3D printed assembly of a bracelet with paraboloid joints and a fold-over clasp sliding mechanism. The assembly was printed on both a uPrint SE Plus (Fused Deposition Modeling – FDM) and an Objet500 Connex3 (PolyJet Technology). The design avoided long through-pins and focused on flexure of small snap arms for the clasp. Clearances between parts were kept above 0.02 inches to prevent fusing. Support material removal was considered to ensure ease of post-processing.

Pros:

3D Printing Moving Parts Fully Assembled – 28-Geared Cube

Product Details: The 28-Geared Cube is a 3D printed desk toy designed to test the capabilities of 3D printing in producing complex mechanical parts. It is a cube with 28 gears, where rotating any one gear causes all 27 other gears to turn in a mesmerizing pattern. The cube has 7 gears on each of its 4 sides, including 2 large outer gears that move in opposite directions and 5 smaller gears inside the cube to reverse the direction of the large gears. The gears are linked through one of the big gears on each face meshing at 90 degrees with one

of the big gears on each of the 2 neighboring sides. The cube was 3D printed using Shapeways’ White, Strong and Flexible material and designed using Autodesk Inventor Professional 2013.

Pros:
– Complex mechanical design that showcases 3D printing capabilities
– Mesmerizing gear movement pattern
– Improved smoothness and reliability with PTFE lubricant application
– Well-designed to minimize clearance issues between moving parts

Cons:
– Initial high friction surface caused jamming, requiring lubricant
– Material used has a rough texture similar to medium grain sandpaper
– Requires careful design and clearance considerations to ensure smooth movement
