Well, finally got round to creating a coin hopper for a Bryans machine, measured an original mm by mm and produced the computer image to export the file to a 3D printer. The object is ok but it needs to print at a higher resolution for smoother finish, the hopper was not made as a replacement part, just thought I would have a go if a part is needed in the future.

Great for complex objects and an interesting project but I think I would rather find a good metal worker to make a replacement part.

Good machine - I recently printed this on an Elegoo Mars - a Bryans coin chute replica, all the dimension were taken from an original and drawn up in Fusion 360

Looks great. Which kind of resin did you use for that?

This is an interesting thread.
We've briefly touched on this subject a few times now without any real substance.

Then suddenly we have acceptable results. Well done those who've dabbled and succeeded.
We have a commonality in brand name and materials used. I'd only heard of filaments and not resin.
Can anyone explain the difference and costs?
Are there tales of success versus failures?
Software options?
Lessons learnt?
Computing resources needed to drive these beasts?
Any buyers' remorse?

Eager to learn

SLA-3D-printers are not expensive. The Elegoo Mars Pro is available for around $250.

I needed the printer for a (missing) payout-cup. On an old german machine the payout-cup was missing, but some traces were still there:

Of course the first step is to create the 3D-model. There are a lot of tools on the market to create such models. I'm using an old version of 3D Max, but there are also free tools like Blender. Here are some pictures of the modeling process:

After that you can load the model into the slicing-software of the printer (in my case Chitubox). You have to add some support-structures (can be done automatically):

Then upload the result via USB-stick to the printer and start printing. After some hours (depends on the height of the model, because the model is created layer by layer) the model is ready for curing in uv light and removing the supports:

Of course, a plastic model does not fit for such a machine, but with the SLA-printed cup you can test the 3D model.
Now you have two choices:
1) You can print the model with a Wax-resin like Power-Cast Burn and create your own Casting mold for brass casting. See this Youtube-video: or
2) use an online-service like i.Materialise.com or shapeways.

I send my 3D-model to i.Materialise.com and this is what they send back:

Now I just have to solder the payout-cup to the base plate.

I think the most important part of the process is to create a clean and flawless 3D model. You have to pay attention to a few things, such as a minimum wall thickness etc ...
