Carbon FP3D

september 29 2025 fda approval ifu updated and sds available overview fp3d (manufactured by keystone industries®) is a two part resin developed for producing flexible removable partial dentures engineered using carbon’s proprietary dual cure chemistry, fp3d sets a new industry standard by delivering a unique combination of durability, stain resistance, dimensional accuracy, and flexibility beyond its material strengths, fp3d easily integrates into carbon’s digital denture workflow, assisting in reliable, economical, and quick production this resin is not currently compatible with the ao polishing cassette docid\ iffh3q8 wlk liqr87bd5 two part resin carbon's two part resins differ from the one part resins used throughout the dental industry in a few important ways the two components (part a & part b) of fp3d are stored in separate chambers in a cartridge, similar to an epoxy you may purchase at a hardware store the components are combined at the time of use by using a battery powered dispenser and a disposable mixing tip once combined, fp3d has an 8 hour life span called a pot life after the resin has aged beyond its pot life, it is not suitable for printing and should be resin handling after printing after printing, two part resins require thermal curing (baking) in a convection oven to preserve clasps and fine features, partials must be salt baking during the baking process some salt will stick to parts during baking and must be washed off afterwards required equipment carbon's two part resins require equipment that will be new to most dental labs cox dual drive dispenser a powered dispenser is required to push the resin components out of the cartridge and through a disposable mixing tip go to cartridge dispensing docid\ fda6pra3 xhqoax3hows3 for more information yamato convection oven like all of carbon's two part resins, fp3d partial dentures require thermal curing in a convection oven to attain their ultimate mechanical properties see thermal curing docid 7ne6rgdaszpapohh5qozm for more information including programming and operating instructions the yamato convection oven has ventilation and electrical infrastructure requirements see the resources docid\ xckd87zq6nzxz3bsamccb for your printer for specific information the oven must be ordered from carbon (pn 101807) because only this model includes the required hardware this item is available form the carbon shop yamato convection oven condenser for high volume production if you will be using approximately 100 liters or more of fp3d annually, you will need to install a condenser to prevent buildup in the ventilation ducting download the handout below for more information salt baking equipment salt baking requires a variety of supplies and equipment including powder grain salt supports parts during thermal curing baking pans oven safe pans that hold the salt and parts salt strainer strains out clumps of salt or other large particulates that can negatively affect part accuracy foil covers the pan and contains salt during baking salt, baking pans, salt strainer and foil see salt baking docid\ whftudzdy0cs0a0 dljcm for more information the above items and more are all available on the accessories & supplies docid 95twe3ttl 5ihi6dnl4xi page resource links about the material technical data sheet (tds) instructions for use (ifu) safety data sheet design follow these design recommendations for partial dentures to be printed with fp3d wall thickness should be 1 3 mm incorporate t bars to prevent splaying of parts during curing add t bars to all full arch partial geometries (uppers and lowers) to achieve the best accuracy t bars should be equivalent to the median thickness of the partial denture lower partial denture with t bars digital preparation

entire workflow from dispensing resin through washing and salt baking resin dispensing dispensing the two part resin fp3d is very different from pouring out one part resins in particular, the 8 hour pot life is a new variable that needs to be kept in mind read cartridge dispensing docid\ fda6pra3 xhqoax3hows3 for detailed information about setup and operation of the cox dual drive dispenser set up the cox dual drive dispenser check the battery install e\ f ratio plates set speed to 1 install the orange mixing tip on the cartridge replace the mixing tip 8 hours after the initial dispense as the resin reaches the end of its pot life slide the cartridge into the dispenser place the shroud over the mixing tip dispense and discard approximately 10 ml of resin to ensure proper mixing, perform the 10 ml burn off for every dispense dispense the required resin into the cassette printing install the cassette with the newly dispensed resin in the printer mix resin in cassette using silicone spatula this mixing helps ensure color accuracy mix resin before every print, including after initial dispense start printing when printing is complete, remove the platform to begin post processing see printing docid\ ilqkpb5tbxc66cmjmgwv0 for more information washing the washing process for fp3d is similar to washing most one part dental resins fp3d has a total maximum solvent exposure time of 5 minutes remove the printed parts from the platform remove the supports from the parts supports are easily removed manually using a blue shop towel can help keep sticky resin off of your gloves first wash add parts to washing container of fresh ipa place container on orbital shaker and wash parts for 2 minutes at 140 rpm detailed cleaning remove parts from ipa wet a toothbrush with ipa and remove any liquid resin from tooth pockets, intaglio surfaces or anywhere that resin can be trapped second wash place parts in container of fresh ipa place container on orbital shaker and wash parts for another 2 minutes at 140 rpm dry the parts place parts on clean surface to dry alternately, use compressed air to dry parts curing fp3d parts must be packed in salt and thermally cured (baked) in a yamato convection oven thermal curing must be started within 8 hours of printing parts must be fully clean and completely dry before baking program the yamato convection oven before parts can be cured, the oven must be programmed with the appropriate temperatures and timings for curing fp3d follow the instructions in oven programming docid\ fze0 qdahovhnvvm6l6kk to program your oven find the precise settings for curing fp3d in the handout under resin programs for the yamato oven add salt to the baking tray use a fine mesh strainer to add salt to a 75 mm (3 inch) deep baking tray add approximately 50 mm (2 inches) of salt shake and/or tap the tray to make the surface of the salt relatively flat replace salt after 10 curing cycles to ensure part cleanliness place the parts in salt parts must be completely dry before placing in salt place each part intaglio side up in the salt gently nestle each part into the salt so that all down facing surfaces are supported by the salt using excess force will deform the part cover the parts with salt using the sifter, add about 25 mm (1 inch) of salt on top of the parts to enable even heat distribution during baking, the parts should have the same amount of salt above and below them shake and/or tap the tray to ensure the parts are settled in the salt cover tray with aluminum foil cover tray with aluminum foil if necessary, write identifying information on a metal tent sign and place it on top of the foil bake the parts place covered tray in the oven start the fp3d bake program 15 minute ramp to 120° c hold at 120° c for 10 hours remove the parts from the oven the tray and interior of the oven will be hot use caution when removing items from the oven wearing heat resistant gloves, remove the pan from the oven and allow it to cool ( 27° c) alternately, parts may be allowed to cool inside the oven fp3d parts will change color after baking rinse rinse parts with warm water to remove excess salt from the surface a toothbrush can help remove salt residue, but it is not required dry parts place parts on a clean surface to dry alternately, use compressed air to dry parts tooth bonding and finishing fp3d partial
