compatible with vertically oriented parts design recommendations carbon does not make splint design recommendations carbon encourages users to follow the guidelines of your design software for example, 3shape splint designer requires a 1 5 mm minimum wall thickness single and double sided splints are both easily printed single sided splint double sided splint perimeter edge ensure that the perimeter of the splint does not come to a sharp 'knife' edge, as this makes support attachment difficult the perimeter should at least be as wide as the tips of the supports to ensure ample space for support connection 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 docid\ vubpoaitblm11am9 qj1p 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 docid\ vubpoaitblm11am9 qj1p 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 docid\ vubpoaitblm11am9 qj1p in docid\ oid4znztzyelttpvj984a course for more information orientation options vertical and tilted there are two options for orienting splint models when using keysplint hard/hard clear vertical (90 degrees from the platform) 40 degrees from the platform read the related sections below for more information about each option carbon encourages experimenting with both methods to determine which best suits your lab's designs and workflow vertical orientation all splints printing splints in a vertical orientation maximizes the amount of splints that can printed at once the information in this section applies to both single and double sided splints orienting 1\ click on orient or shift + o in the top bar in the printer interface 2 in the lower right corner of the bottom bar, turn on overhang detection or v key and set to 40 degrees areas that need support will appear red red 3\ orient the splints so they are about parallel to the platform 4 rotate the models 90 degrees with the anteriors facing the platform the models should be standing vertically, perpendicular to the platform surfaces that have overhangs will require supports surfaces with supports will require finishing to ensure proper seating supporting supports hold up the part during printing they do this by connecting platform facing surfaces to the platform enter support mode click support in the dark gray bar at the top of screen under position , select above platform to lift parts off the platform click the manual tab and make sure patch is selected add supports click on the anterior surface of a splint to select a patch under the patch tab, adjust the overhang to between 40 and 60 degrees select a value to ensure that the patch covers the six anterior teeth in the primary support type dropdown menu, select fence fences are easier to remove and require less finishing than other support types enter a spacing value between 2 5 and 4 mm make sure the boundary fence checkbox is selected margin value should be 0 mm examples of well supported splints single sided splint double sided splint tilted orientation single sided splints orienting proper orientation of splints is critical maximizes yield by minimizing print defects achieves the required accuracy and surface quality single sided splint 40º tilt with anterior rotated away from platform intaglio surface facing platform orientation of single sided splint 1\ click on orient or shift + o in the top bar in the printer interface 2 in the lower right corner of the bottom bar, turn on overhang detection or v key and set to 40 degrees areas that need support will appear red red 3\ orient the splint so that the intaglio surface is facing the platform 4\ adjust the splint so that it is mostly parallel with the platform 5\ rotate the splint so that it is at a 40 degree angle from the platform with the posterior close to the platform supporting enter support mode carbon recommends using fences they are easy to remove and do not increase the footprint of the splint, enabling more to be fit onto the build platform click support in the dark gray bar at the top of screen under position , select above platform to lift parts off the platform click fence adding fences make sure toggle platform (b key) is off this will hide the platform and allow a clear view of the splint while you are adding supports click overhang detection or press the v key set to 30º 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 to create the fence geometry this may take a few minutes click done in the upper left corner when finished notes support the entire perimeter entire perimeter of the platform side of the model avoid supporting areas that come in direct contact with teeth avoid supporting areas that come in direct contact with teeth as this can affect fit and function z rotation of splints you have freedom to rotate the part in the z axis to suit your needs properly supported single sided splint 40º tilt with anterior rotated away from platform intaglio surface facing platform tilted orientation double sided splints which side will be supported? double sided splints are oriented similarly to single sided splints but determining which side should be supported requires comparing both sides using overhang detection carbon recommends supporting the side that has the fewest overhangs and thus requires the fewest supports this has a number of benefits part accuracy resulting from fewer unsupported overhangs on intaglio surface minimizes time creating the supports in the software reduces resin usage reduces finishing time by minimizing support nubs each splint is evaluated by duplicating it, flipping the copy, turning on the overhang detection tool, and then seeing which part has the fewest overhangs (red area) if there is not a clear difference, then either side may be supported orienting proper orientation of splints is critical maximizes yield by minimizing print defects achieves the required accuracy and surface quality double sided splint 40º tilt with anterior rotated away from platform mandibular or maxillary surface facing platform to minimize supports parallel to platform perform an initial orientation of the model so that it is roughly parallel with the platform with the posterior region facing the lower portion of the screen 1\ click orient in the main bar in the printer software 2\ adjust the splint so that it is mostly parallel with the platform either side of the splint can face the platform duplicate and flip now the splint must be duplicated and flipped click layout in the main bar in the printer software click the splint model to select it enter 1 in number of copies and click duplicate a duplicate of the model will appear click orient in the main bar type 180 in the y axis field and press enter click layout again move the models apart from each other so they do not overlap you now have 2 copies of the splint one with maxillary impression facing the platform one with mandibular impression facing the platform rotate double sided splints now both splint models need to be rotated so that we can compare the overhangs click orient in the main bar make sure both models are selected rotate the splints until the anterior portions are at 40 degrees from the platform the posterior of the splint should be touching the platform compare overhangs click toggle platform button in the lower toolbar or press the b key to hide the platform this will allow you to see the overhang areas clearly click overhang detection or press the v key and set to 30º to find areas that need support orient the camera so that you see the models from the platform side and can clearly see the red overhang areas orbit around the models to make sure you can see all overhang areas you may want to adjust the model tilt ±5º to reduce overhangs you can adjust the models independently after carefully comparing the models, delete the model that has the most overhangs if there is no clear difference in overhang area, just pick one the remaining model is now ready to be supported supporting enter support mode carbon recommends using fences they are easy to remove and do not increase the footprint of the splint, enabling more to be fit onto the build platform click support in the dark gray bar at the top of screen under position , select above platform to lift parts off the platform click fence adding fences make sure toggle platform (b key) is off this will hide the platform and allow a clear view of the splint while you are adding supports click overhang detection (v key) and set to 30º to find areas that need support click a series of points on the perimeter of the splint to define a fence 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 to create the fence geometry this may take a few minutes continue steps 1 4 until the entire perimeter is supported adding patches double sided splints may require additional supports, especially for overhangs on the anterior lingual surfaces use patch supports for these areas click patch click an area of overhang under patch, set overhang to 30º set primary support type to fence check the boundary fence box click generate all to create the supports repeat as needed for additional areas of overhang notes support the entire perimeter entire perimeter of the platform side of the model avoid supporting areas that come in direct contact with teeth avoid supporting areas that come in direct contact with teeth as this can affect fit and function double sided splints may require additional supports on polished/cameo surfaces polished/cameo surfaces if the supports are attaching at a horizontal angle , they may detach during printing causing part deformation supports should attach to the surface of the part that is facing the platform creating vertically oriented support tips please reapply the supports and move the attachment points to address this issue if this problem occurs z rotation of splints you have freedom to rotate the part in the z axis to suit your needs properly oriented and supported double sided splint 40º tilt with anterior rotated away from platform intaglio surface facing platform nesting select the layout tab layout tab (shift +
