Professional 3D printers like Sharebot Voyager, Andromeda and Voyager WARP allow to optimize the jeweler workflow thanks to easy to use and intuitive tools which create economic and replicable production cycle in their laboratories, saving time and cost.
Sharebot offers to professional and jewelers not only the printers but also the right material to produce jewels: it is the photosensitive resin SHARE-IC, a material developed by our technicians exactly for the casting process. SHARE-IC guarantees the casting of jewels like rings and pendants, giving high quality result even on the smallest detail and it can be used for traditional casting process.
To realize a jewel starting from a 3D model (sketched with all the common used modeling softwares), it’s important to follow few steps, reported here below: it’s a simple process, fully replicable in every professional workplace:
1 – Creating a 3D model
To properly cast a model realized with SHARE-IC, you must follow few important rules: the object surface mustn’t have any hole and all the junctures and intersections must be closed. An “open” model will cause failure during the casting process.
2 – Support material
Support material allows to print correctly the model without failure. It’s important to understand where supports must be placed. You can manage supports via Sharebot DLP Slicing software interface (Sharebot DLP 3D printers managing software. Read more about it on the Sharebot Voyager user handbook).
3 – 3D printing
A Sharebot professional 3D printer creates a model with SHARE-IC castable resin in just few hours (Sharebot Voyager WARP completes the process in few minutes!), Further details about the printing process are available on our support pages dedicated to Voyager, Andromeda and WARP.
4 – Post-Curing
Post-curing process cures the SHARE-IC resin once the object is printed. Before starting the post-curing, the supports must be removed. A correct post-curing requires to expose the model to UV light with a wavelenght of 405nm with a power of 0.5W per minute. A good post-curing allows to succefully complete the casting process.
5 – Preparing the casting process
After a correct postcuring operation, the model has a smooth and polished surface without any imperfection. If you see some remainings on the surface or the model has not been cured correctly, the casting process will fail. If the model is clean, you can start to prepare the casting tree and cylinder.
6 – Draining channels
Draining channels allos the resin to drop away from the model during the casting process wihout leaving remainings or imperfections. To achieve best results, it’s very important to understand where draining channels must be placed on the base of model size and the position of the object on the building plate.
7 – Burn-out and casting
The jewel is ready to be cast. Let’s prepare the casting cylinder (the process is the same used for the wax). SHARE-IC is compatible with the products normally used for burnout and casting. The hoven must be pre-heated at 850° for 45′ and the operation lasts 1h for a small cylinder and 2h for a bigger one. To avoid any failure, times and temperatures must be respected.
8 – Metal model
The casting process is over and the metal jewel is almost ready: it’s raw and a few casting remainings on it.
9 – Polishing
The raw jewel must be polished to remove all the remainings: you can use the usual jeweler tools.
10 – Jewel
The jewel is ready: jeweler can put jems or incision. Once this last procedure is over, it is ready to be put on the market. In just a few hours, you can realize a real object starting from a 3D model without leaving your benchwork, saving time and costs amd improving also your workflow.
