Chocolate printing vs casting? I need to make chocolate busts.
Is it better to make silicon reverse of the bust and cast the bust or directly print it using chocolate printer (I prefer cost and process speed over quality)? I don't have chocolate printer so if this method will be better I will need to use some 3D printing service.
I need to make quite a large amount of the busts.
In my experience, direct printing of chocolate is tedious because:

It has to be around 88 C to melt; and
It doesn't solidify very quickly at normal room temperature.

Unless you can print in a chilled environment (freezer is better than refrigerator), you will likely wind up printing a chocolate puddle. Even then, you have to heat not only the reservoir but also the entire nozzle (or it may solidify in the nozzle).
Also, some chocolates have issues if they freeze or become overheated, so it's a very tight tolerance with the temperatures.
