--- title: Carbon FP3D slug: materials/fp3d description: Discover FP3D, the advanced two-part resin from Carbon specifically engineered for flexible removable partial dentures. This durable and stain-resistant material leverages Carbon's innovative dual-cure chemistry to ensure unmatched flexibility. docTags: createdAt: 2025-01-28T17:47:33.901Z --- :::hint{type="success"} **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. ::::VerticalSplit{layout="left"} :::VerticalSplitItem 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. ::: :::VerticalSplitItem ![Available Shades](https://res.cloudinary.com/carbon3d/image/upload/t_auto_quality_format/Education/Materials/dental/FP3D/Transparent-line-image.png "Available Shades") ![Original Pink | Light Reddish Pink | Dark Veined | Opaque](https://res.cloudinary.com/carbon3d/image/upload/t_auto_quality_format/Education/Materials/dental/FP3D/FP3D-shades.png "Original Pink | Light Reddish Pink | Dark Veined | Opaque") ::: :::: Beyond its material strengths, FP3D easily integrates into Carbon’s digital denture workflow, assisting in reliable, economical, and quick production. :::hint{type="success"} This resin is 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. ::Image[]{src="https://res.cloudinary.com/carbon3d/image/upload/v1741908650/Education/Materials/dental/FP3D/Two-components-epoxy01.jpg" size="70" width="1103" height="890" position="flex-start" darkWidth="1103" darkHeight="890" showCaption="false"} - 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 [disposed](docId\:kQYgmwDX_5LNp-uy81_Xt). - After printing, two-part resins require [thermal curing](docId:7NE6rGdaSzpAPOHH5QOzm) (baking) in a convection oven. - To preserve clasps and fine features, partials must be [packed in salt](docId\:wHftudZDY0cS0A0-dljcm) during the baking process. - Some salt will stick to parts during baking and must be washed off afterwards. ## Required Equipment :::hint{type="info"} 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.** ![](https://res.cloudinary.com/carbon3d/image/upload/v1741911058/Education/Materials/dental/FP3D/Cox-dispenser-on-bench-and-in-case01.png) Go to [Cartridge Dispensing](docId\:FdA6pRA3_XHQoAx3hOwS3) for more information. :::::VerticalSplit{layout="right"} ::::VerticalSplitItem ### 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.
