TOPIC: Make your own Gelatinous cubes

Make your own Gelatinous cubes 2 Years, 8 Months ago  
I posted a few months ago a thread about a way to obtain cheap Gelatinous cubes. They were quite good but a little too small for my liking.

I therefore launched into a project for making my own cubes. There a lot of postings on the net of people who made their gelatinous cubes and many of them (including those) inspired me:

I acquired the following material:
Super Sculpey from local artcraft shop.
Envirotex Lite (1/2 gallon) from local artcraft shop.
EasyCast Clear casting Epoxy (8 oz.) from local artcraft shop.
Mold Max 30 (Trial size) from Smooth-On
SuperSeal & Ease Release 205 Combo Pack from Smooth-On
Lot of 100 2*4 Lego block from eBay
GW/Citadel Green Ink
Degasing apparatus, glassware, micropipets and electronic balance from the lab I work in...

I started by sculpting by hands some Super Sculpey to the right dimension and shape so that it would fit nicely the DF 2 inches corridors (it took me 30 min and then I baked it for 30 min:



I then assembled Lego pieces so that it would form a casing just the right size to encase the sculpt while balancing between the strength/thickness of the silicone mold and sparing the expensive silicone:



I then put wide scotch tape on the inside of the Lego pieces to obtain a smoother mold (not sure it was necessary). I then used a piece of glass which I sprayed generously with Ease Release 205 to put underneath the casing. I coated the sculpt generously with SuperSeal, I've let it dry for 6 hours and then put it upside down into the mold casing.

See Image 1 below

Mold Max 30 is a super strength Silicone made of 2 parts that cures in about 45 minutes once mixed. You unfortunately need an electronic balance to mix the parts as it is done by weight and not volume (10 times part A to 1 time part B). Having never worked with this material before, I thought degassing Part A before the mixing with part B could be a good idea to save time:

See Image 2 below

It degassed a lot under vacuum. I then added part B and mixed both components for 10 minutes:

See Image 3 below

I then poured the liquid silicone around the sculpt until the level of silicone was flush with its base. I let it cured overnight. Unfortunately, I found the next day that degassing was not done properly and there were some bubbles trapped in the silicone mold.

I proceeded anyway with the pouring of my first resin cast (Envirotex Lite mixed equals volumes of each parts; 80 ml supplemented with 20 ul of GW Green Ink). After overnight curing, the end result was the following:

See Image 4 below

I could see my fingerprints all over the cube, its green color was a little too pale for my liking and there was way too much bubbles trapped in it.

I then decided to coat my original Super Sculpey sculpt with a light coat of Envirotex Lite to remove my fingerprints. I then prepared the cast of another silicone mold while degassing for 20 minutes once the 2 parts were already well mixed together. It turns out that the 45 minutes working time was long enough to do just that. After repeating this a few days, I was able to make a total of 4 silicone molds (only the first, top left on the picture, with a few bubbles and my fingerprints):

(It is really annoying not being able to edit your own posts while trying to post an image now properly formatted to be the right size...)

Anyway, Here are the images that did not upload properly (hopefully).

Re:Make your own Gelatinous cubes 2 Years, 8 Months ago  
I played around with degasing Envirotex Lite itself after it had been mixed but I found out that the quickest way to minimize bubble formation was to mix both parts very slowly so that bubbles are not formed in the first place. I also found out that 30 ul of ink per cube gave me the color I wanted.

With my half a gallon of Envirotex Lite, I have been able to cast 18.5 cubes. A few times, the resin shrunk a little during the curing process which sucked air into the mold along a few corners. Perhaps this would not have happened if I had sculpted a cube with more rounded corners. I also found that pouring a little more of uncured Envirotex Lite into the mold about 15 minutes after the initial casting minimized this phenomenon. I also found that for some unknown reasons, about 20% of the cubes were still a little sticky even weeks after the original casting. Perhaps I had not mixed the 2 parts long enough? I am in the process right now of giving all my cubes a last coat of gloss varnish to give them a shiny/liquidy/slimy appearance and I think this will solve the stickiness problem.

In testing different products, I also tried some EasyCast Clear casting Epoxy. It's about the same price per volume as Envirotex Lite (both expensive) and I did not experience any shrinkage/stickiness issue with it. I've cast 4 cubes with it with the amount of this resin I had and I can unfortunately no longer distinguish which 4 cubes of the 22 I have were done with this product.

So, here's the final product:

I shudder to think of exploring a dungeon stocked with 23 Gelatinous Cubes!!
Excellent work. Have you tried making any with the remains of adventurer's inside?

A few of you contacted me having some interests in my cubes. I decided to sell 18 cubes (who needs 23 anyway...) by pairs each week until I have none to sell. For those of you interested, just do a "gelatinous cube" search on ebay. The auctions start at $0.99!

Best,

I received the Gelatinous Cubes today and I have to say they are awesome. I’m glad I didn’t miss out on getting a set of these. I can’t wait until I can place “Double Trouble” on the gaming board. The cubes are so cool I had to setup a cube in action. The photo pays tribute to “The gelatinous green cube” art of Raymond E Gaustadnes.

I'm very glad you like them Sobakawa, congrats on winning the first auction and thank you for showing your appreciation. Although I do not know who you refer to with your tribute, I must say that having a source of light behind a cube before taking a picture really shows it advantageously. Also, I see you have a lot of Hirst Arts casts and other goodies. If you have not yet looked around on the DF forum, I suggest you do, as you'll find plenty of advices, tricks, splendid setups, cool custom projects as this present one, and of course plenty of beautiful official Dwarven Forge pieces, all related to "dungeon decorating".

Best,

Bio

p.s. Part of the reason I am selling these cubes by pairs, apart from my laziness to avoid setting up twice as many auctions, is that having 2 cubes is a lot of fun!... especially if you have one show up around the party at each end of the same corridor, mouhahaha.

The mighty casey has swung and missed 2 times. Beware folks.... My dungeon will have some Gelatinous Cubes from Biowizard.

Beware the next auction....

What I would like to know is what degassing equipment was used in the mold-making process. Could we get a list, please...?

Hi Wolf 359,

I did not use any fancy equipment. Since I already work in a molecular biology lab, I just used one of the the vacuum breaker there is available beside each lab benches, aside the air and gaz breakers. If you feel like investing in a vacuum system available at your home, you can visit the Hirst Arts forum. Many people have done it there. I would not recommend going this way though just for a couple of gelatinous cubes. I guess a sealed chamber, tubing and electrical pump sells for more then $200! Just buy my cubes! ;-)
