CAD software is increasingly being used for designing unique and appealing jewelry shapes which are both beautiful and complex. With advanced 3D printers readily available, you can literally get all types of jewelry designs transformed into reality. To achieve best result, your 3D CAD model needs to comply with certain stipulations so that the glow and originality of jewelry attracts customers instantly.
We would share with you the factors you need to take care of while creating model for 3d printing for stunning outcomes.
Always maintain good resolution for your STL file
The STL file of your 3d jewelry model should be of reasonable resolution so that it can be sent across online easily and triangles are of smaller size. This would ensure smoothness of printed surface and no large, pixelated chunks. Such chunks result in large triangles causing roughness of model’s surface leading to use of more gold, platinum or other expensive metal. When the projected surfaces would be refined, costly metal would be lost.
Make provision for adequate number of release holes if model is hollow
Release holes should be included sufficiently, a minimum of 3, when you create a hollow model. Your jewelry’s design and dimensions would dictate how large would be the holes’ size. However, experts are of opinion that the size should not go below 1.5 mm at least.
Always provide sufficient support
You need to give completeness to the shape with proper support. Let’s understand this with an example. You have to design a ring. For it, the top and bottom need to be joined together with a wire. If wire is absent, the ring would simply appear to be made of two separate elements.
Boolean the model components together for accurate prints
The wire in above point should Boolean together the ring’s top and bottom. When we talk of Boolean in 3d product modeling, we mean that the design would be leakproof. The printer would efficiently work if the model is watertight and not composed of separated elements. New printers are allowing non-Boolean jewelry designs to be printed but those machines which assure superlative prints unavoidably seek complete models.
Delete the rail lines for a smoother printing experience
Professional 3d designers often use rail lines to give shape to the model and then remove them before sending to print. But, if you forget to eliminate them, they would slow down the printing and make it erratic. Always ensure that your final printable model is free of all elements not visible to eyes.
Set the size of head prongs proportional to stone table
If you are facing difficulty in corner stone fixing, this must be because of shorter head prongs. The commonly accepted rule is that if the stone size exceeds 3mm, the size of prong must be 1.5mm at the top of the stone’s girdle. Such large prongs are not needed if stone diameter is less. If you start using taller prongs for channels featuring small stones, you would have a hard time setting up the corner stone. Usually in the channels, prong’s height must be corresponding to the stone tables’ level.
Try to remain away from sharper angles
When carrying out custom 3d modeling, always steer clear of projections or sharper angles. If your jewelry design has to essentially carry sharper edges, mellow down the angles by putting in fillets adequately.
Create separate parts if your polishing brush can’t reach model’s certain portions
If you are unable to access a specific region of the model with your polishing brush, then it is advisable to create the model in separate elements. This is an integral part of jewelry creation process. If you fail to comply with the same, you would end up with a model that may have appeared seductive on the computer screen but in reality would be dull and unattractive.
Choose the 3D software that best suits the purpose
The 3D printer optimizes on the features of 3D modeling software to accurately print. The 3D software usually can be categorized broadly into two classes. One is designed with features to facilitate seamless 3D printing whereas the other helps designers to materialize their creative ideas uniquely. You can succeed as an artist if you consciously use the software for your specific purpose based on the situation and needs of the jewelry design.
Set the thickness of model’s wall wisely
Often, you would run into issues when the printer won’t be printing smaller elements of jewelry because of thin walls. You need to keep an eye for the thickness of model’s wall all across the design to ensure that it doesn’t go below printer’s required specification. If the jewelry’s wall has more thickness, it would become fragile and would break apart if pressure is applied.
