Materials Overview

introduction carbon resins are the raw materials from which parts are built using digital light synthesis™ these curable liquid polymers are shaped using a series of projected uv light images all parts printed on a carbon printer have isotropic material properties due to carbon's patented clip technology click a link below to go to a specific material group dental materials docid\ ljaakrscgxl6ccrigvprj elastomeric materials docid\ fp8qh0b0nmeh9r3jqtzai rigid materials docid\ xvyop41s1t9wjdnpyidv valuable information is available as printable handouts to be used in your production facility dental post processing grids docid\ bpjqrhgawlhchkvgppy2l lab reference grids docid\ ujf4k0ny4lye74zohx1r safety data sheets (sds) an sds is a document that lists information relating to occupational safety and health for the use of various substances and products these documents can be found on carbon's main website here www carbon3d com/stewardship pricing current resin pricing is available from carbon resin price list docid\ sgkqmmrk w9 liwbjql5x (login required) compliance and safety documentation safety data sheets and other compliance related documentation (rohs, reach, etc ) for all carbon resins can be found at https //www carbon3d com/stewardship one part resins these materials are single component formulations they are typically best suited for prototyping or specialized applications, and are used extensively in oral health characteristics single component poured directly into the cassette reusable printed parts are cured using uv light only optional color mixing mechanical properties lower mechanical strength & abrasion resistance bottle of dpr 10 resin two part resins these materials consist of two components, part a and part b they are packaged separately and must be combined and properly mixed before being dispensed into the printer cassette for printing see resin mixing and dispensing docid 4lwk3k36rfqf2raovxszx for more information on mixing options and processes the mixed resin has a defined pot life or working time, generally 8 hours please refer to the material protocol sheet for the exact pot life for the material in question characteristics dual component resins part a & b part a & b mixed at the time of dispensing limited lifetime (pot life) for use once mixed dual cure printed parts are cured in an oven to achieve ultimate mechanical properties mechanical properties strong and abrasion resistant cans of rpu 70 part a and part b dual cure carbon resins are unique due to their dual cure process the first cure occurs during printing, where dlp projection of uv light sets the liquid resin into a solid shape this initial uv cure creates a "green state" part, which is solid enough to be handled, cleaned, and prepared for further processing the second cure, known as the thermal cure or bake, involves a precise thermal process performed in a convection oven during this step, the material undergoes extensive cross linking, transforming into a highly durable, engineering grade material material selection selecting an appropriate material is a critical component of the part's success this selection process can be complex and confusing the following information offers some guidance comparing to common thermoplastics in some cases, there may already be a thermoplastic that is commonly used for the part in question to provide a better understanding of how carbon materials compare to some common thermoplastics, please consult the document below this table compares carbon materials to common thermoplastics such as abs and tpu download carbon alternatives to common thermoplastics see the blog on carbon's website for more information about how carbon's materials compare to thermoplastics choosing a material another way to approach materials selection is to review the application's critical performance needs what material type best suits the needs of the application? rigid elastomer what temperature resistance is required? what chemical resistance is needed? is biocompatibility a concern? what mechanical performance is needed? strength impact consult the documents below to help find answers to these questions more in depth information can be found on each material's tds (technical datasheet), available on the website material properties this table lists the properties of all carbon materials in one place great reference for engineers and designers! download material properties chemical compatibility this online table shows the chemical compatibility for most of carbon's materials view chemical compatibility table
