Thanks for the comments. I guess it's my Airfix roots showing again. I'll try a 'frameless' option and see what the robot says...

Which factory did you work at? I have a few mates that worked for Airfix and Lesney.

Sorry, I should have said  "Airfix kit-building roots"!

Ah okay.

For what its worth there is only one guy on this forum whom I would consider to have the knowledge and practical experience regarding 3D printing.  ;)

Interestingly, I tried a minimalist design, just a pair of rods joined at two points, and the price remains the same:

Yes, you are below the minimum item price.

Crikey!!!  If that is now the minimum price for small Shapeways parts, I am glad I have ordered my own SLS system!

I produced hundreds of SLS parts for model ships through Shapeways and the minimum price I paid was about 2.50 for the smallest part.  Because of their latest shenanigans, and the pound/euro exchange rate, I took the view that it would be cheaper in the long run to have my own system.

Not cheap, but essential for what I do.

It's a pity these parts you guys design and have 3D printed are bespoke, otherwise I could offer my services!

Do tell?

I am all ears...... PM me if you feel it would be better.

The reasons I use 3D SLS printing is because of the following:

1.  Injection moulding is too expensive for the numbers I need.
2.  White metal casting is too heavy and yesterday's technology
3.  Resin casting is too messy and the moulds dont last.

The problem is sls is pretty low quality compared to what 3D printing is capable of.

TBH if I was doing more than a few then I'd print or create a master and then resin cast it. It isn't that bad or messy.

Cheers Mike

Exactly what I was implying if you wanted a large number of parts produced I could offer my services!

As Mike has just mentioned PU casting is without a doubt your best alternative, and it isn't messy if your organised with the right equipment, I still cast resins along with thermoplastic injection.
