Advice on 3D printing please - my Mini Media Centre design

more expensive than i thought it'd be

How much is a sheet of bendy-mdf and some glue ?

Thom, those resins and Prime Grey are UV cured stereolithography, which means as time passes they tend to deteriorate. The materials that last are Polyamide and ABS. Between those two, polyamide is tough and flexible, while ABS is more brittle.
Yea, that's been my concern about the various 3D printing materials, that they're not fit to last. There will be heat from the hardware and there is also the issue of direct sunlight. That's why I've not used the prototype in styrene I made.
Polyamide is new to me. I've not used that. I'm more familiar with ABS, but not in context of 3D printing. I'm also wondering how the finish is here, as it appear to differ quite a bit.
And I suspect I need to paint it myself in order to get ther colour I want, and then it's also a matter of how these materials react to paint.

Ditto. I'd hoped the prices would have been somewhat cheaper by now.

Cost of production time?
I do have a model produced, but it took a very long time. I was hoping to be able to create with more stable materials in a reasonable quick time.

That's expensive.
A block of wood CNC'd would be cheaper.

That and milling machines was how I made the first (and only) prototype.

According to the number of pieces you want to produce I would choose more classic workflow like molding.

Polymide is what I used for my 3D printed lamp.
Some people have made polyamide 3D printed guitars(pictures and video). Freedon of Creation sells lamps, shoes, and jewelery and furniture made with polyamide.
I think the best way to check out the material is to order something small like the samples available from Shapeways or i.materialise. Because the material is so porous, it is often dyed rather than painted, so that the color soaks all the way through.

hmm.. then it'll be somewhat matt then?
-
Yes, somewhat matte. The red and white models here are polyamide - the red one is dyed(from Shapeways). The two translucent models are acrylic, similar to Shapeways FUD material.

I remember Thomthom when you first posted this, the design still inspires me!
