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

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
