The final groundwork for your mold making

 We can 3 d print many diverse things, and perhaps not most of them have to function as final merchandise. Instead, we could make a variety of tools, templates, containers...or even casting molds. This particular solution may be your main topic of our present article. We'll show you how to cast materials like wax or soap, in household states using readily accessible tools.

Our purpose is to demonstrate that casting from silicone molds is significantly easier than it might seem at a first glimpse. And so, I am hoping I can now help others save some material, time, and effort Silicone molds.

Notice: The images below show which I used an old PEI print sheet for a work pad. This has no specific purpose, use just about anything instead -- do not risk damaging your perfectly usable print sheet

Material for mold producing

To produce the mold, we'll use a two-part, condensation cure silicone rubber. In our instance, it's a native Czech made product known as Lukopren N Super, however, there are many similar services and products you could probably obtain available worldwide, for instance, Smooth-on, ACC Silicones, RTV, etc..

Lukopren is made up of part A (silicone ) and part B (hardener/activator) plus it cures at room temperature, at approximately 24-hours. Fixing time is affected by the amount of hardener and ambient temperature.

You can use it in order to cast many materials including polyurethane, epoxide, plaster, cotton, concrete, cement, wax, low melting metals or soap. This mold material is suitable both for small, step by step casts and large items (i.e figurines ). No vacuum pump will become necessary as a result of exceptional flowability and very low viscosity. Silicone rubber can be both brushed or poured on (using a thickener added in to the mix), though you can find better choices for cleaning like for example Smooth-on mentioned previously.

Metal casting will be clarified in detail in our forthcoming article, focused on jewelry manufacturing and dental uses.
