Now that is a challenge tf !

Although on a serious note I have considered printing a scaled down small working model of a basic allwin - this would take some considerable time though.

Judging by the numerous bandit rebuilds you have done, I seriously doubt that, as with any skill it's just a matter of getting used to and familiar with the right tools for the job.

But but but... didn't you used to work in IT? !PUZZLED!

I guess the trick would be to upscale slightly to allow for casting shrinkage. Nice work. !!THUMBSX2!!

With the improvements in resins in the last two years the making of strong internal slot parts is what interests me. The ability to make broken or missing parts that are simply no longer available anywhere or to make and use parts while waiting perhaps years to find a real one really appeals. Even quite common parts that are often hard to find such as coin slides (especially German ones) jackpot and gold award activators. Perhaps the casting of parts from 3D made moulds might be the best way to go?

If the industry brought out 3D filaments made of wax instead of plastics.
Then it would be ideal for doing "lost wax casting".

BP !THUMBS!

That's a point. Surely somebody already thought of this? !!IDEA!!
It would need a much lower temperature setting on the printer.

Then the next phase of 3D printing will probably interest you Paul.... 3D metal printing. Still in its infancy with regards to hobbyists, but I am sure it will not be long before we see small units for home use. The metal, which can be steel, stainless steel, copper, etc goes through a 3 phase process:



Not sure how strong the printed metal item is, or whether it will withstand the stresses that a normal metal object would, as I said, in its infancy but an interesting development. Some of the software that converts the 3D design will also scale up the object automatically to allow for thermal properties of metal shrinkage when cooling.

There are some filaments (Polymaker PolyCast) and resins (PowerCast) for printing wax models with 3D printers.

Typical for me that.
I once spent a fortnight designing how to fry food with water. Before I realised I'd just reinvented the pressure cooker.

Only this week I got excited when I worked out that fitting a focusable, Electro Magnet Impulse generator to the front of an emergency vehicle could paralyse a fleeing scrote's vehicle with immediate affect. Thus John Law would be able to feel their collar without chasing them through a town centre at 80 mph until they plant it through Tesco's. Things were looking hopeful until I learnt that The Soda Springs, Idaho Sherriff's Office gave up on the idea 10 years ago after Detroit started fitting electronic, drive by wire technology in their cars to control braking and steering as well as engine management. It was viewed that turning off their steering and brakes as well as their engine could be deemed as un-sportsman like in the extreme.

Oh well, never mind, back to my idea for putting rice through a popcorn maker as I think it might make a decent breakfast cereal. I'd call it Crackle, Pap and Snop.
