CNC brass engraving from an stl file

[Statstastic]

Hi guys,

Micheal, Jonathan, I've sent you a request for an email address so I can send you a file.
Musht, The little characters of mine are quite detailed so it's going to take a while to machine the inserts. Unfortunately 3d printing isn't an option :-(

Hey MrJazz, did you get the mini mould test sample file I sent you, the one with just the 3 figures on? What would you want from me to machine that beauty? Please don't worry about the 'faceting' on the background surface, it's meant to be like that. I know this project is a challenge, but how dull would life be if we didn't try something new every now and again?! Also, bear in mind that I'm not asking anyone to give their time fro free and If you only knew what it was for you'd bite my hand off at the chance to become a partner!

You probably already know, but you can get things printed in metal. Even gold plated! I have been meaning to try out one of the services when I find the right object...

I have making candle holders in plastic, I am told that is a "fire risk"- would be better in metal or ceramic.

Hi Bob,
I'm inclined to agree that a plastic candle holder may be a fire risk!

DMLS sure is amazing. Ultimately though, it's a composite, so I wouldn't be sure of it's structural integrity for moulding purposes - particularly under pressure. Also, it's still very expensive, so it would be a costly way to find out that it definitely can't be used. Machined metal moulds on the other hand, are a tried and tested technique.

Good idea though.

Hi S,

Yes got it and thats relatively easy just will be time consuming due to requireing some very small cutters using tiny stepover amounts.!! The tiny cutters also increase the chance of tool snappage to scarey levels. .

The multi figure plate is the real challenge to cut and keep detail and will take a massive amount of time and again due to tool breakage potential not something I'd like to do for the laugh.?? . . Can you imagine being 18hours into 20hour job then the toolsnaps and wrecks the mould. . Arghhhhhh don't come near and the air would turn blue in London even thou I'm in yorkshire.!!

Hey Jazz,
I completely respect what your saying about the risks involved and I wouldn't want to be responsible for you uttering profanities. In terms of snappage I've got 3 x 0.3mm ball nose cutters and 2 x 1mm end mills going spare which I bought when I thought I could do it myself. Let me know if you'd like any.
