This is the 3D printed final prototype for a radio based project I worked on for my university course. The main body is printed on a Zprinter 450 powder printer that bonds powder material with a liquid adhesive. The speaker trim, radio face trim and button/knobs are all printed on a 3D Touch printer, which is an extrusion printer.
I had to sand down all of the surfaces and apply Pollyfilla and/or primer filler to achieve the desired surface finish. Once ready, I applied the final layers of paint.
The making of the speaker trim and grill can be seen here.
The following is a photo presentation of the final prototyping methods I used.
The first 3D printed body prototype was printed in two parts, with a wall thickness of 1mm. After seeing the first prototype it became obvious that I would have to increase the wall thickness. I also decided to print the body in one piece which would eradicate some of the complexities associated with the assembly process.
Applying super-glue to the body to increase the strength of print.
Applying paint to the raised details.
