Haven't tried cleaning it, is ipa ok? Composition seems similar to sla resins. Makes sense if that works tho, I'd have to use lack3 on top regardless. Ipa worked fine, it's now matte but I think lack3/5k sandpaper will make it shine, now I just need to find a nice color to use, thank you very...

That sounds like a very good way (and an easy one) to have the same thickness for faceplates and oxygen-free curing, just need to find another piece of glass that fits in my curing chamber and I'll try this first, thank you!

looks very useful, didn't think of flipping the glass too, thank you!

Ok, I'll try a second cure with glycerine/glysol, thanks!

How do I make faceplates? I have the shells ready but if I just try putting some fotoplast on glass and exposing it to UV it stays sticky on top, thought the problem were the alcohol dyes or acrylic inks I tried but even plain fotoplast behaves the same, not sure what to do

I'm about to order the materials for the shells of my first ciem, I plan on using gks for drivers, should I use cerumen filters at the end of the tubes? Even looking at the ones made by companies I see that some use them and other (most) don't, is there a reason not to use them? Wouldn't they...

You should checck the MSDS of said dyes, some are quite corrosive/irritant/reactive, alcohol based dye only means that it has a certain polarity, given the quantity it'd probably be fine but it might react with the resin (if it's not made for the resin you're using) so you're better off by...

Thank you!

So I'm fine with just cutting both past second bend? Or should I leave some extra channel lenght? It's my first time doing that so I don't really know what to do for trimming

The other one is ok or should I get both redone? to my untrained eye it seems quite good

It seems like it didn't reach the otoblock, I'll try and have that one redone, not sure when tho, thanks

It's a bit shorter but it looks even more so because the right one has more material on the bottom, I don't have a caliper right now but it's not much shorter

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)

Thanks, I can't seem to find it on ali, amazon, ebay, digikey or mouser, I can only find with a 3mm ID ptfe tube for 3d printing extruders or metal tubes, on Ali soundlink only has up to 2.5mm ID, what do you search for it? Would ptfe or the petg from the filament work too? Density is similiar...

Hi, I decided on building my first ciem with a 3d printed shell (FDM, usp VI biocompatible clear PETG) once I find somewhere to scan the moulds (that doesn't ask 160€ for scanning alone) and was looking for a build not too complex as a first one (single driver so that I don't have to deal with...
