overview dreve fotodent® cast for carbon printers is now available to produce crowns and removable partial dentures the material is a transparent red resin that burns out without any residue for dental casting this course will cover digital pre processing of your crowns and removable partial dentures to properly prepare them for printing with fotodent® cast for carbon printers this resin is

designs sprues and crossbars sprues and crossbars the addition of sprues and crossbars to parts helps with print quality especially when faced with particularly complex geometries clasp connectors clasp connectors it can be helpful to add features that connect both sides of the tooth clasp these must be made in your rpd design software and can be removed from the part after printing crown carbon recommends designing your crowns as usual dreve fotodent® cast for carbon printers requires no special considerations crowns general orientation & support information hide the platform use toggle platform (or press b ) to hide the platform before orienting parts this will make it easier to see overhangs and place supports use patch and fence tools to create supports patch tool the supports speeds up support creation by automatically supporting an area with just a few clicks it is useful for supporting larger areas of overhang that would take longer to support manually it is often useful to support your parts with this tool before manually adding supports fence tool supports are manually placed by the user and are best suited on linear overhangs or smaller areas fences provide stability while leaving smaller nubs than the default bars option review supports docid\ vubpoaitblm11am9 qj1p in printer ui docid\ oid4znztzyelttpvj984a course for more information partial

support he part and obscure the rpd surface click the select multiple supports select multiple supports icon in the top menu bar select multiple minor supports multiple minor supports using shift click or click and drag with the mouse click delete delete in the top right corner or press delete/backspace on your keyboard to remove selected supports repeat steps 2 and 3 as necessary until all noisy supports are removed remove intersecting supports carefully examine your model to look for supports that intersect the denture geometry if you have intersecting supports, they must be removed

when necessary add supports on the outside of the clasps when necessary repeat steps 2 and 3 as necessary until all intersecting supports are removed add supports to overhangs add supports to large overhangs (red areas) to maintain part quality click the multiple supports multiple supports icon in the top menu bar add support(s) to overhangs add support(s) to overhangs as needed click generate generate in the top right corner to create support structures repeat steps 2 and 3 as necessary until all large overhangs are properly supported notes do not over support the model too many supports will make post processing challenging typically, supports should be no less than 2 3 mm apart use the measure tool measure tool in the lower tool bar as needed supporting overhangs add supports to islands islands are parts of the rpd that will float away if they are not connected to the platform with supports unsupported islands will create problems further along in the print 1 position the camera so you are looking straight down on the platform push the reset camera icon push the reset camera icon in the lower left corner of the screen to return to the default view push ▲ to look straight down at platform ▲ to look straight down at platform camera tool 2 click toggle clip plane toggle clip plane in the lower menu bar or press the c key c key this provides a cutaway view of the model 3 move the clip plane handle all the way to the left move the clip plane handle all the way to the left so the clip plane is at the level of the platform moving the handle slowly to the right will move the clip plane away from the platform, revealing more of the rpd this simulates the printing process of gradually building the part as you move the handle, different areas of the part will be revealed each new area is potentially an island each new area is potentially an island these areas must be supported to ensure an accurate and complete build use clip plane to analyze supports 4 move the handle back to the left 5 slowly move the handle to the right you will initially see only the bases of the supports eventually portions of the rpd geometry will appear portions of the rpd geometry will appear 6 when a new island is revealed by the clip plane when a new island is revealed by the clip plane , stop moving the clip plane and examine the new island 7 position the camera as needed to see the underside of the island 8 add a support to ensure the island prints add a support to ensure the island prints 9 continue moving the clip plane to search for islands, adding supports as necessary check for islands properly oriented and supported removable partial denture intaglio surfaces face away from the platform tilted 50 degrees from platform minor supports removed overhangs supported islands supported side view of properly supported partialtop view of properly supported partial crowns orient proper orientation carbon recommends no overhangs on crown margins no overhangs on interface surfaces minimum overhangs on buccal/lingual crown surfaces following these recommendations will maximize accuracy and minimize the need for manual finishing top viewside view 1 in the lower right corner, turn on overhang detection or v key overhang detection or v key set to 40 degrees to indicate areas that need support in red 2 click on orient or shift + o orient or shift + o in the main bar in the printer software 3 orient each crown so that the margin and interface are free of overhangs margin and interface are free of overhangs 4 refine orientation to minimize overhangs on other crown surfaces minimize overhangs on other crown surfaces the margin and interface of each crown should now be free of overhangs the remaining surfaces should now have the minimal amount of overhangs note margins and interfaces that have overhangs will require supports these supports affect fit and will require finishing to ensure proper seating overhangs support enter support mode

overhang detection or press the v key set to 40 degrees to find areas that need support click esc key on keyboard to end a fence and begin another carbon® recommends making a series of small fences, rather than making a single continuous fence, to give greater flexibility to reposition points hold down the e key and click with the mouse to reposition points click generate generate to create the

on margins no supports on interface surfaces minimum overhangs on buccal/lingual surfaces crown side viewcrown iso view add supports to incisor because incisors can be longer than other crowns, they require supports in areas that do not have overhangs these extra supports prevent sagging as the part prints ensuring excellent accuracy click toggle platform button toggle platform button in the

either default or dynamic dynamic mode will print in approximately half the time due to this, print forces are elevated, requiring greater vigilance in supporting of the parts unsupported regions with larger cross sections such as horizontal sprues and crossbars should be supported across their length to increase print success printing with release film can make part removal easier once printing is complete if using release film, select print with release film slicing select either standard or fine fine slicing results in finer features at the cost of a longer print time print controls for
