Pressure pots

I JUST got into dice making and have come across the problem of bubbles overtaking my dice. I know it can be fixed with a pressure pot but I refuse to spend 200€.
Do I need negative or positive air pressure to get the bubbles out?
If it’s positive I guess I can find a way to connect a bike pump into a cooking pressure pot but I have no clue what to do if it’s negative.

A Dragon I sculpted and turned into a resin kit

I sculpted this dragon in 10 parts (last picture) with Beesputty, Sculpey and a bit of epoxy clay. I then made molds for the parts and started casting it in resin.

Sculpting this dragon in separate parts was a pain in the ass. Looking back I should have sculpted it completely and then cut it into parts. I thought I would be able to get the parts to fit better if I sculpted them separately (which is kind of true), but it was really difficult to get a good view on the pose and the proportions.

The wings are made with thin brass sheet with polymer clay over them. They are nice and thin, but still thick enough to get good casts.

I originally started sculpting because I wanted to make my own resin kit, and I cannot believe I finally did. It was a long journey, but the results are far better then I had expected them to be.

Uncured resin

I’m VERY new to two part resin and even though my first cast went perfectly and cured nice and solid everything I pour keeps turning into goo.
It acquires this very thick honey-like texture but it doesn’t really cure at all.
It’s genuinely gone downhill, my first pour was perfect, the second one was a bit squishy but it hardened just fine after a bit and now my last two pours are just a thick gooey mess.
I suspect it’s the ink, though it’s totally possible that I’ve just screwed up the ratio.
Any tips?

Find a better curing machine

I’ve been using curing machine for a while, and it’s been okay, but I still run into uneven curing, failed pieces, and sometimes bubbles that ruin smaller projects.

I mostly make jewelry, charms, and small decorative molds, so I’m looking for something more consistent rather than just easy to use.

Has anyone here switched to the new curing machine? Did you notice better curing results or fewer failed pieces?

Would love to hear honest thoughts before I buy one.

Help! What silicone adheres best to plastics ?

Hey all !
While we spend most our time trying to make sure our Moulds dont stick to resin, In this case, I'd like the opposite.

I have a set of Resin 3D printed parts that I would like to coat in a thin layer of silicone. My question to you all.

What silicone, during its curing process, adheres best to plastics ?

Thank you, have a lovely weekend

Casting indoors? Fume hood?

I'm casting PU-resins from Smooth On, and due to living in a country with high moisture I'm strongly considering moving my operation inside. I do have a pressure pot where I put my parts to cure, but that still leaves fumes from mixing and pouring, and since the only spaces I can cast in is the living room, I'd like to not contaminate the area too bad.

How have you dealt with fumes when casting indoors? I'm considering a simple fume hood for the pouring at this point.

Recommendations for highly pigmented liquid dyes for UV resin (Crystal clear + Deep colors)

Hi everyone,

I'm currently setting up my jewelry brand and will be using HeyClear UV resin. I'm on the hunt for the best liquid dyes (no mica) that are fully compatible with UV curing.

My goal is to achieve rich, deep, dark colors—especially a deep "blood red"—while maintaining perfect, crystal-clear transparency. I’ve had issues with pigments blocking UV light or preventing a proper cure in the past, so I'm looking for high-quality, highly concentrated dyes that won't compromise the curing process.

Does anyone have specific brand recommendations or tips for getting that saturated, glass-like look without the resin staying sticky?

Thanks for the help!

Aphrodite in the roses

This was my first time using the INSANELY (stressfully) fast white resin, which gives a work time of maybe a minute once mixed, and has to be done in small amounts so it doesn’t flash cure; flowers done in standard epoxy resin in different batches to give some color variety amongst the entire selection.

Does anyone know a good resin or additive to mimic Bone/Ivory?

I'm currently on a quest to make custom pieces for a game that my family likes to play and I would like to make them out of something that could mimic like old bone or ivory. Including the slight yellow twinge that those materials take on after age.
