Not sure where i’ll be going with this post, but here goes anyway
The CAD work progresses with the C64 mini keyboard keycaps and it’s getting close to the time where I need to be thinking about the end-game, the final product.
I can’t imagine that people will be happy with some watery grey colour, most would prefer at least some semblence to the original breadbin colours!
So, i’ve done some quite considerable googling on the subject
.Also, figured that ‘painted’ stuff used to commonly use the RAL standard to determine a standardised final colour, maybe there’s a RAL colour for commodore keycaps? (there’s one for the case!)
Turns out that finding 3D printer resin in the colour you want, isn’t easy
Also, turns out that creating your own 3D printer resin colour also, isn’t quite fully tried and tested yet
a fantastic website –
and, many, many more websites were found, all with various anecodes, photos and information regarding colourant successes and failures
One colourant kit that kept cropping up – https://monocure3d.com.au/product-category/cmyk-pigment-set/?v=322b26af01d5 The Monocure CMYK kit.
So, it looks like if I want to create my own coloured resin, I’ll have to mix it myself.
So, where to start, and what ‘stuff’ to use to dye it?
Turns out that there’s a distinct terminology that may need to be used to figure out just what the process of colouring resin is.
has an interesting summary.
However, for my purposes of colouring the resin..
If I use a Dye – the colours will likley be a little more ‘washed out’
so, i’ll need to use a Pigment – essentially an insoluble bunch of micro particles that sit in suspension in the resin and create a solid, opaque colour! – AKA Dark brown.
So, off to google to figure out Pigments
There’s pigments for Casting resins, Resins, Acrylics, everything…..Except, a clearly stated pigment that’s suitable for 3D printer resin!
Infact, just what is 3D printer resin? what chemicals
I found this website which goes into some depth about resin types
Also found another website that does resin pigments in a range of RAL colours
BUT, they go on about Polyester, epoxy, and I’ve no idea if those things are compatible with the Anycubic resin i’m using
Another google and, I come up with a chemicals safety sheet for some Anycubic resins –
Listed there is a key component – which ends in “acrylate” and “diacrylate”…
so, looks like it’s an acrylic / acrylate based resin? can’t say i’m a chemistry expert but an Acrylate is a group of chemicals, so i’ll run with that
I need to look for pigments suitable for use in Acrylates!
But, err, is it an Acrylated Epoxy, or an Acrylated polyester, or even something else?
2-hydroxy-1-(4-(4-(2-hydroxy-2-methylpropionyl)benzyl)phenyl)-2-methylpropan-1-one is part of it!
has some amazing information, including use in photosensitive resins
I’ve found a few websites that suggest urethrane acrylates are the go for UV resins
or, is it Acrylate polymers, or Epoxy Polymers!…….I’m leaning away from epoxy
SO, here goes – a quick google for Acrylate Polymer Pigment
I give up!. I’m just gonna buy a couple of bottles of ‘stuff’ and just see what works, This stuff seems to be recommended, and cheap, it’s brown and dyes resin, what can go wrong!
