Jewelry design went through a lot of change due to the arrival of advanced 3D printing tech. The old type of design, with hands and other tools, is replaced with 3D modeling software and 3D printers, but the creativity is still the most important factor.
Every piece of jewelry has its characteristics, and many of those determine the actual process of the creation. The shape of the object is one of these features. The creation of simple jewelry pieces through the 3D tech is simple, but those more intricate pieces require a bit more work. If the desired object has a lot of small holes, then you should cast it in several pieces. This will make polishing a lot easier. Rods and similar shapes are also very hard to cast, but you can add them later, or you can pay someone who is skilled enough to do that.
The size of the jewelry piece is also significant. You can, and you must measure the size through width, length, volume as well as other relevant parameters. The size is necessary for the creation of the mold. Large shapes might require different molding flasks, so be sure to measure them before you design your piece of jewelry. You can create multiple patterns if the overall size of the objects is the same. Don’t try to build multiple molds if the difference between objects has anything to do with the design. If one object is straightforward and lumpy, it will need more time and higher temperature to cast than an object that has smaller parts (for example, the spider web that will become a central piece of the necklace). Flask for mold casting cost money, so beginners should use only one flask. It might take more time for the creation of multiple objects, but this saves money.
Many amateur 3D jewelry artists make one fundamental mistake. They forget the weight of the metal. Every metal, gold or silver or any other metal has its weight so the artist has to predict the weight their work will have. The calculation of the possible weight of the object (jewelry piece) requires some simple conversion, but this isn’t the accurate representation of the weight. Knowing the exact weight to volume ratio of the metal will help you get a slightly more precise result.
How sturdy the metal is should determine the minimum thickness of the object and its pieces. Two different steps in the creation of the 3D design jewelry can suffer due to the lack of depth in the object.
– First, there is the casting process. If the thickness of the object is small (less than 1.5mm) then the liquid metal won’t be able to fill it, and both the mold and the object will become useless.
– Metal shrinks while it cools down. A 1.5mm gap will more than often result in 1mm object which is too weak. Go for 2mm or more as it will lead to a solid object which will not break down.
