The client bought this secondhand NAS from a thrift store and designed the NAS enclosure by himself. He made a plastic case with his desktop FDM 3D printer, and came to us for PMMA manufacturing. Some of our clients really take pride in custom PC building.
Solution
Step 1: The client measures the dimension of his medical devices, and builds the model of the enclosure, then exports the STL file for printing and the DXF file for laser cutting.
Step 2: Here we print the parts with FDM 3D printing technology using FDM PLA, which is the most cost-effective solution for this application.
Step 3: Take the prints from the plane. Adding a raft or skirt would make this process easier.
Step 4: Polish the prints manually with grater and sandpaper to remove the remaining marks.
Step 5: Laser cut the acrylic boards and drill holes as required. Finally, assemble all the parts with the devices, and fix them with screws.
