In 2003 I started a small engineering company, designing and manufacturing parts, mostly for the Automotive industry. In 2006 I needed to design a part which closely fitted round a pre-existing cast component which was near impossible to measure. The final part needed to be CNC machined - but after a half dozen prototypes that were not sufficiently good a fit - I bought a 3D printer (a BFB3000, dual head) to speed up the design iterations. It paid for itself in saved CNC time within 6 months! I upgraded to an Ultimaker Original a little later for improved print quality - and hoped they would produce a dual extruder option. If BFB made it work - and it worked well - Ultimaker should be able to - no? Then I upgraded to a U2 - as it appeared to offer higher resolution - though in practice the 20 micron prints were little better than the 50 micron and they were only a little better than the Original. The heated bed was a big improvement though. It could produce decent quality prints a fair bit faster than the UO - and I was happy with that. In 2013 I sold part of my company - to allow me to concentrate on design. The U2 has been invaluable in that. Since I have provided consultancy and worked in many different areas. I'm still surprised how few Engineering companies make use of 3D Printing! Fortunately, I can help there! My last contract was working on Special Effects for Star Wars VIII at Pinewood. They were quite enlightened on the 3D Printing front - with many different printers, and many U2's. This job was the most fun I've ever had in Engineering!
