What Resin To Use? 1 Year, 4 Months ago  
Sorry i accidentally put this in the ASK DF forum and meant to put it here so here we go:

Hello all i was thinking about buying one of the dungeon accessories molds to outfit and dress my 5 sets i got from the KS. My question is what material should i use to cast them in any suggestions or sites?

There are a lot of options, I've just started exploring mold making and resin compounds myself. I don't know enough yet to make a solid recommendation, but I have heard from several sources that resin casting wears out most mold compounds faster than the various plasters. There are some very durable plasters than can still deliver very nice detail replications.

While I hate to send you elsewhere, there is a wealth of information on the topic already on the Hirst Arts site. I plan to acquire some of his molds later, mainly for variety in accessories, extra dressing, and crafting some of the actual buildings I want. For myself, DF's products have an edge over Hirst's offerings, but I would never denigrate his product line.

There is also information out there for making your own vibration table pretty cheap to release air bubbles more efficiently, which combined with a surfactant seems like a pretty good way to save material costs by reducing bad casts.

One of my local hobby stores carries both mold making and resin casting material in stock. I'm going to ask around a bit to find someone who has used it and see what they think of it. I would prefer to work with materials I can source locally if they are decent.

My players rue the day I bought "Dragon Mountain". Ever since they give every creature a bit more respect. You never know when the GM will decide that this group is crafty...

Crimson_King_of_the_Tower, Can you tell us which dungeon accessories molds you are talking about? Hirst Arts? I'm not aware of any mold being sold by DF.

The most common source for casting material and mold making is: www.smooth-on.com/

I wouldn't know what to recommend.

A new mold from Hirst Arts costs $34. Unless you absolutely want resin (and you know it will damage the rubber in time...) you might consider plaster. For only $3, you can buy casts of those pieces in "Merlin's Magic" (a very hard substance) from Naloomi's Workshop. You might have casts from multiple molds to save money and have more diversified accessories. For myself, I prefer the sculpts in resin from Thomarillion even though they are more expensive.

I have about a hundred little plaster thingies made in hydrocal. I think I broke only one in 5 years. The smaller and most roundish they are, the sturdier they become. I would suggest a plaster sturdier than plaster of Paris though. The beauty of plaster is you should not even care if it breaks, especially for accessories. You can just cast more. Also, the painting is so easy for simple pieces such as crates. A simple ink application + varnish as Bruce describes thoroughly on his web site does the trick.

The company Biowizard referenced for the materials is the same one my local shop carries products from. Also, as Biowizard notes, there are several kinds of plasters. Some are very durable once they cure, but also have a low enough viscosity to get into the crannies and details. The big thing from what I understand is a surfactant, which helps the material flow into such spots better. Let us know what you decide to try and how it turns out!

Plaster will not work for the tiny parts. These mold are what finally pushed me into resin casting. If you use baby powder and mold release the molds will last nearly as long as if dental plaster was utilized. I have cast these 15 times each now and can't notice any degradation.

The problem with plaster is not necessarily its durability but in cast quality. Even with a vibrating table and wet water the casts of tiny parts are of marginal quality.
