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 compatible with the 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 docid\ kqygmwdx 5lnp uy81 xt after printing, two part resins require docid 7ne6rgdaszpapohh5qozm (baking) in a convection oven to preserve clasps and fine features, partials must be docid\ whftudzdy0cs0a0 dljcm 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 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 docid 7ne6rgdaszpapohh5qozm for more information including programming and operating instructions the yamato convection oven has ventilation and electrical infrastructure requirements see the 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 https //shop carbon3d

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 connect to printer connect to the printer using your web

horizontal t bars do not add fences to areas higher than about 30 mm above the platform these areas require bar supports add docid\ vubpoaitblm11am9 qj1p support overhangs that are more than 30 mm above the platform add bars to any overhangs where fences did not generate add bars to reinforce fences reinforce fences that support clasps or other delicate features for best accuracy, do not under support clasps nesting select the layout tab (shift + l) in the top menu bar under auto layout, select gen2 gen2 usually gives the most efficient packing for dental devices enter at least 1 mm in

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 variable that needs to be kept in mind read 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 for new cartridges this standard procedure is known as burn off if you are experiencing discoloration in your parts, we advise the following ensure that you are following proper burn off procedure and dispensing at the speed specified in the https //docs carbon3d com/files/technical data sheets/carbon fp3d ifu 4920047 rev 0 pdf if discoloration persists, burn off resin for every dispense , not just new cartridges 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 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 docid\ fze0 qdahovhnvvm6l6kk to program your oven find the precise settings for curing fp3d in the handout under docid\ fze0 qdahovhnvvm6l6kk 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 dentures require a final uv cure cycle see step 3 below for more info video the numbering of the steps below differs from the video above workflow finish teeth and base according to your lab's standard practices bond the teeth to the partial denture follow the tooth bonding instructions for your tooth material of choice perform the final uv cure fp3d partial dentures require a final uv cure
