Out And About With Proto 2

The second prototype functioned much better after the minute changes made from Proto 1.  The shots came out much better too as I gave a lot more exposure time and used 400 ISO film instead of 100.2015-01-21 12.40.50 The 3D printed tripod mount really improved stability and allowed me to angle the camera.  And I promise, once I get a half decent method of processing the negatives I will upload the photos for all to see.  Stay tuned!

Fast Prototyping, Fast materials, Fast Learning

I used temporary methods that were adequate for the prototyping stages.

Although the light chamber will have printed inner walls, I used a thick marker pen to black out the chamber.

I plan to use transparent red acetate sheet for the shot number window.  Keen to test the camera and with plenty of post Christmas sweets lying around, I used some clear red wrapping from a Quality Street chocolate.

3D Printed Final Prototype – Radio Project

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.

Speaker Trim & Grill Prototype

The following is the process behind making my speaker trim and grill.

Image

Before 3D printing I had to re-thread the material through the printer head, ensuring a secure bite.

After removing the base material I sanded down the faces, coated the trim in Polyfilla, rough sanded, coated in Pollyfilla again and then sanded to a smooth finish with a fine grade of wet and dry paper.

I applied two coats of primer and then two coats of silver spray paint.

I used the bottom of a soup pot and a pair of women’s elastic leggings to create the speaker grill.  I secured the leggings into place using a cable tie and removed the excess material.  I secured the grill with a little super-glue and a glue-gun.
