I'm not in a hurry (been trying to work out how to get this done since about April...). Sadly I'm in the UK. I'm just looking at quotes from Shapeways, and realising that 200mm along the Y axis is BIG and therefore expensive (like several hundred quid even for the "value" materials). Right now I'm pricing a 125mm long version. Would you recommend Shapeways, and if so what material(s)?
Right now, printing the entire model as one piece, dish and all, they're offering Multi Jet Fusion Plastic at (round numbers) £70, TPU at £160, SLA Plastic at £500, PA11(SLS) at £135, Fine Detail Plastic at £175, and aluminium for £1400 (!).

Getting so they'll even give me a quote is a massive step forward so thanks again.
