Oyumaru Reusable Modelling Compound Assorted Colours 24 Pack

Product Information

So as the old adage goes: if you want something done well and are too poor to pay someone else to do it, do it yourself. So here you are, dear reader – the simplest and most wonderful guide to Instant Mold you will ever find. Taking ornate details and transposing them onto another model, like lifting a wall engraving from a Cities of Death building and putting that design onto a Sisters of Battle Tank.

Turn any old toy into a genuine 40k terrain piece with a tasteful smattering of skulls and cogs. This stamp mold was pulled off a Cities of Death building. The oyumaru is a material with a similar consistence of a hard rubber at room temperature that soften with heat application and can be use to acquire a certain form that will conserve once it cools down. The big advantage of this material is that it can be reshaped lots of times, making molds of certain pieces and then repeating the process to make molds of other pieces with the same material. I guess that with a big number of repetitions the material will end up degrading but for the moment I haven't had any problem and I have heated it a lot of times. There are other craft thermoplastics on the market. Some brand names are Polly Plastics, PolyDoh, PolyMorph, ThermoMorph, Friendly Plastic, and Moldamer. These may be similar to InstaMorph, or they could have different melting points and hardness after forming and cooling. Thermoplastics with Polymer Clay? You can weigh the quantities but I find simpler to take the right quantities with a syringe, specially for small pieces. Is important to always take the compound A with one syringe and the compound B with another one. If you change the syringe a part of the resin will cure inside it and render it useless.When I first looked at instant mold, it became apparent that its re-branded 'Oyumaru' a Japanese craft item. Even imported, its cheaper and available in many colours. There are several thermoplastics on the market for DIY and crafting use. I also tested one called InstaMorph. This is a very different product with vastly different uses because the plastic itself is much harder than Oyumaru. InstaMorph comes in a resealable pouch filled with white plastic pellets. The melting process is similar; just pour into hot water and wait for the pellets to melt. The pellets turn completely clear when melted. You can then scoop them together into a ball and form the mass into a shape. Once cool, InstaMorph turns white again and is very hard. I did make a push mold with InstaMorph, but it’s not really suitable for this purpose as there is NO flex at all and you can’t un-mold anything you cast into it. But it can be used to create rigid molds. Honestly, I've turned away from instant mold products for the time being, partly because of the issues mentioned by the OP. In my town, there is an art school which has spawned lots of art supplies stores - some of these sell RTV silicone (not instant mold, takes half a week to make a two part mold) at prices cheaper than the internet. While start up costs and learning curve can be significant, here it is cheaper mold for mold and cast for cast than the instant mold + epoxy method. Radomes, doors and windows being cast. The upright door to the left of the 50p shows how thin you can make a casting.

Two syringes: one for compound A and one for compound B. In this case is almost compulsory to label them clearly as it will be a real problem to mistake them. This is the same recast part after some trimming and cleanup. Be sure your hobby knife is extremely sharp – greenstuff is rubbery, and a dull blade will sometimes bend floppy bits instead of cutting cleanly through them.It really does the job and the level of detail is great! I haven't tried it that much yet but from what I can tell, it does an exact replica of the object copying. Instant Mold, like most other pleasurable objects, should be firm yet slightly rubbery to the touch.
