howdy yall
almost done with my first ciem
working on the faceplate right now and so my question is:
How can I put the circuit board holding the zobel into the faceplate with fotoplast?
i put the zobel on a small board (will fit, already checked) and would like it to be within the resin of the faceplate.
would i be able to suspend the board in the middle of curing resin or would i have to do this in layers?

Do you want it as aesthetic design?

yes

 

[raygunraymond]

anyone try using a vacuum to get bubbles out of negative molds?

 

[mattmatt]

yes

If you want it to look great, you should embed it directly to the resin.

Can you show me a photo of the PC so I can plan it out properly?

 

[mattmatt]

yes

I never had problem my mold having bubbles. How do you melt yours?

As counterintuitive as it might be a vacuum might even increase the amount of bubbles :

ill get maybe 1 small bubble once in a while
i use a wax melter

do you know how krystalloid would react?

No. But I never have problems with bubbles, sometimes there is one or two bubbles and if so I simply remove them with a piece of wire.
If you work to quick with fotoplast bubbles are more annoying - but they can be fixed by simply sanding them open and filling up with some more resin. It’s a bit tedious but not a big problem for me.

If you want to get rid of bubbles in a mold, a pressure pot would be recommendable.

If you want to get rid of bubbles in a mold, a pressure pot would be recommendable.

But if you compress your agar agar or whatever you use. Wouldn't you alter the shape of the mold? Such a soft material will form under such pressure wouldn't it?

Yeah, I forgot to mention that. I personally only use silicone to make my molds.

Got those done today by an audiologist, how far should I trim them? Also do you recommend a more flexible or rigid material for shells? (filoalfa medical flex pla or colorfabb ngen flex for flex or smartfill clear biocompatible petg)
