About Project

Housings and enclosures for components such as medical devices, industrial apparatus and consumer electronic housings like key fobs, have integral manufacturing requirements. Most need to be void-free, strong, air or water-tight, and often highly cosmetic. Some require materials compatible with medical imaging, electro-static dissipation or electromagnetic shielding.

Beijing Institute of Technology cooperated with Academy of Military Medical Sciences to develop advanced automatic medical equipment. During the R&D process, 3D printing and CNC machining are often applied to build the enclosure.

The build volume of FacFox's large-format SLA 3D printing is 244*800*800 mm, and the build area of our large-format FDM 3D printer is 300*700mm.

Solution

• Step 1: Examine the 3D models and list all the requirements after communication. The model is not simply a hollowed-out enclosure but has a movable drawer. Also, the client plans to put the integrated electric components inside, so we print all the inner components of the enclosure.
• Step 2: 3D print the enclosure and inner units with SLA 3D printing technology, using ABS-like resin. The tolerances are accurately controlled for assembling.
• Step 3: Clear the prints with IPA to remove excess materials. Polish and paint with appointed color.
• Step 4: Assemble all the parts with screws. Screenprint the logo of Beijing Institute of Technology and Academy of Military Medical Sciences.
