These are the type of materials i am talking about. [link=http://production3dprinters.com/materials/sls]Mats[/link]
For these you need an industrial system.
As I say, currently home printers are OK for what they are, good for toys and models used during development and concept stages, but if you want something functional ( a real part to be used for a long time) , that needs to take working loads, is UV stable, has a wide temperature range and of high accuracy, you have to go to another level.
I personally have been involved with this in both, usage and development of technology for 15+ years, it’s great, the future of manufacturing as far as I am concerned.
I lecture on the subject for Universities from time to time but my main use of the technology is in rapid manufacturing, supplying Aerospace, Automotive, Military, Formulae one (for on car parts), medical, Oil and Pneumatic systems and of course R and D for all applications.
I think the sudden public awareness of this technology is great, but it has been around for a long time, original SLA technology has been with us for 25 years!
I can see the day in maybe 10 years when home systems will be at a high level.
But currently, to use AM technology (Additive Manufacturing) to its highest level you need a controlled environment with a powerful laser (some new systems are running up to 400 watts). Additional gas supplies of Nitrogen or Argon are also required to purge the build chamber. Temperatures within the chamber reach up to 180 Celsius on plastics and much higher on metals.
All of which prevent the currents high level systems being used at home.
