3D Sign – Maintenance Shop

User comments

This is the low tech design method that I used to produce the sign:

– Use exisiting MS Excel sign layout drawing
– Finalize in MS Word to get a better border
– Convert to .pdf
– Use Zamzar Conversion to make it a .jpg
– Use Shapeways 2D to 3D to make the model
– Submit model
– Hope
– Get printability report
– Back to square one or two for some
– Order a 3D ‘print’
— (In the cheapest practical material)
– White, Strong and Flexible was ‘On Sale”!
— It is a sintered white nylon
– Success! Shipped August 9, 2013

Painting the sign:

– Although I had had success with Tamiya hobby paint, I tried:

…thinking that automotive paint would be more durable. It all turned bad when I sprayed the Krylon UV coat. The Rust-oleum wrinkled badly so off it came and I went back to Tamiya:
– Sealed with Krylon UV Resistant Clear Gloss Acrylic
– Primed with Tamiya Fine Surface Primer Item 87064
– Painted with Tamiya Italian Red TS-8
– Flat sanded the raised letters and frame with 400, then 600 grit
– Voila’ – intended to produce a sign with a red background and white letters
– Sprayed it with Krylon UV Resistant Clear Matte Acrylic
