    The Castable Resin of FormLabs enhance the work of jewelers more quickly and economically than with traditional methods.

    Resin Castable is the help that every jeweler needs to make his creations directly from his 3D design. From CAD software you can print the desired design with the Form 2 3D printer and within a few hours have a prototype to cast directly.

    All the pieces that are printed with the Castable Resin get the perfect qualities for casting:

    • High precision: The precision of the laser of the Form 2 is able to realize precise and clear details that transmits to the piece fineness and very detailed tips.
    • Great finish: Thanks to 25 and 50 micron layer heights, an ultra smooth surface finish is achieved, which means less metal loss and less polishing of the casting later on.
    • Opaque Resin: The wax-like appearance of Castable Resin highlights the finer details and thus helps verify the prototype before melting.
    • Low cost: The platform of the Form 2 allows printing up to 50 rings at a time with a material cost of only 0.10€ per ring, something totally unthinkable with other traditional methods.

    • Burning performance: FormLabs has specifically developed this resin free of ash and residues subsequent to the investment casting process. Castable resin is optimized to provide the best burning performance, but the specific melting process must be adjusted by each user.

    For all the above, the Castable Resin in combination with the 3D printer of Formlabs Form 2 is the essential tool for every jeweler or producer of metal parts of great detail to make parts in the fastest, simplest and most profitable way. To know how to perform the whole process, visit the section on usage tips.

    Due to the great demand of this type of resin by jewelers, Formlabs has developed a material for more demanding users: Castable Wax. This moldable resin contains 20% wax to provide a safe casting without ash remains, a smooth and precise finish at levels of such high power that high-end jewelry elements can be created. Castable Wax offers enough strength for handling without the need for curing.

    In jewelry, pieces stand out according to their complexity and superficial quality, making it essential for a jeweler to surprise his clients with creations of incredible and innovative details. The resin Castable Wax (20% resin) in combination with the 3D SLA printer Form 2facilitates and speeds up the manufacture of pieces of jewelery by offering an easy and clean casting of such incredible elements as this bracelet:

    Next we explain the necessary steps to obtain the final piece from the 3D model in CAD with Castable resin and Castable Wax:

    1. Print the piece

    Once you have chosen the pieces you want to make, you import the files into the FormLabs lamination software (PreForm), where you simply need to select Castable Resin and layer height, import the files, generate the supports and start the printing on Form 2.

    2. Cured (Castable resin only)

    Once the pieces of IPA Isopropyl Alcohol (Form Wash) have been removed and allowed to dry, the pieces must be cured for 120 minutes in the Form Cure at 45º C to reach their maximum mechanical and melting properties.

    3. Wax tree

    With the pieces already cured, the supports can be removed, always with great care. To achieve total elimination of the support and a perfect finish you can use sandpaper (grain 400 or higher) or even a rotary tool with a polishing attachment. The placement points of the wax deposits are made in the same way as for the case of lost wax.

    4. Preparation of the mold

    With the base of the drinker connected to a flask, previously wrapped in tape in case of holes, pour the laundry slowly, always on one side of the bottle to avoid damaging the wax tree. Don't forget to perform the degassing process in the vacuum chamber according to the manufacturer's instructions for use.

    5. Burnout

    The flask is placed in the oven always following the instructions of temperature and time of the manufacturer and then the desired metal is poured for the final piece.

    6. Washing and polishing

    After casting, the mold is carefully removed and the investment is washed. Once washed, the pieces are separated, polished and reviewed until the desired finish is achieved.

    Below, a series of usage tips are cited that must be taken into account at all times with the use of Form 2 with their respective resins:

    Change cartridge:

    Changing the resin cartridge of the Form 2 is very simple, just close the top cap of the ventilation duct (vent) and remove the cartridge by holding it by the handle it has. Then the other is inserted and the vent plug is opened in case an impression is to be started. To avoid drips through the 3D printer, this process must always be carried out with the resin tank mounted.

    After finishing each impression the vent plug must be closed so that the resin maintains its properties. In addition, if you don't use Form 2 for some time, you should keep the cartridge in its original box to keep the properties of the resin intact.

     

    Resin tank:

    Each type of resin must have its resin tank, which must be changed after using 2L of resin. FormLabs has developed a more powerful tank, the Resin Tank LT, which has a life up to 20 times longer than the standard tank.

    To protect and store the excess resin in the tank after each printing, FormLabs supplies a lid that ensures a perfect closure. Once the tank is closed, it is recommended to store it (with resin and lid) in the original box so that the resin doesn't lose its properties when exposed to UV rays for a long time. Another point to keep in mind is that the tanks can't be cleaned with any cleaning product or similar (for example, isopopyl alcohol), since they lose certain qualities that can cause continuous failed impressions.

    Failed printing:

    When an error occurs in printing may be because solid parts of a previous printing have fallen to the resin tank. In this case, a spatula at 45° must be passed through the printing tank, gathering all the solid parts in a corner and removing them. To ensure that the tank resin doesn't contain any solid parts, the resin should be cast with a 190 μm paper filter. Once cast, it is put back into the tank and it is ready to be used again.

    Isopropyl alcohol:

    Isopropyl alcohol is the key to the washing and post-processing of parts made with Form 2 and you should know when it is time to change it. In the Finish Kit the moment to change it's when the IPA (Isopropyl Alcohol) is so saturated with resin particles, that after washing the pieces are still sticky. At that point you must remove all the liquid, clean the container well and throw new IPA, but never fill in on the previous one.
