--- title: Project Analysis slug: software/project-analysis description: Project analysis is the last step before printing a project in Carbon's DLS production. The analysis provides print stats and warnings for a few potential print defects. This guide will show you what tools you have available inside the printer software. docTags: createdAt: 2024-07-01T22:48:06.346Z --- Project analysis is the** last step **before printing a project. The analysis provides **print stats **and **warnings **for a few potential print defects. This lesson will show you what **tools **you have available inside the Printer UI and **how to use them.** # Print Stats ::embed[]{url="https://vimeo.com/1044184984?dnt=1"} :::ExpandableHeading Video Text - **Print Time Estimate**\* - Use this for quoting and production scheduling. - \* Minor variations in actual print time may occur. - **Required Resin Volume** - This is the minimum amount of resin to dispense. - For multiple prints, add the part and support volume for each additional print ::: ### View Details ::::VerticalSplit{layout="middle"} :::VerticalSplitItem ![View Details](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/BEE36xuhiUPiyMha1Stk2_view-details.gif) ::: :::VerticalSplitItem Full project details are also available from the Project Analysis tab. Click “**View Details**” to access this information ::: :::: # Estimated Increase in Soil Load ::embed[]{url="https://vimeo.com/1044184972?dnt=1"} :::ExpandableHeading Video Text - For users with Part Washer(s) in their fleet, analysis provides an estimated increase in soil load per solvent type. ::: # Unvented Volumes Project Analysis detects **unvented volumes** in the project. Unvented volumes are trapped internal spaces that develop vacuums during printing. The pressure build up in the vacuum traps resin and causes defects. Reference [DLS Printer Dynamics](docId\:U7XYytjyDp3BvsYy2qKcU) for more information. ::embed[]{url="https://vimeo.com/1044184935?dnt=1"} :::ExpandableHeading Video Text - Drag the slider to assess red areas flagged by the software. - This \[1st] red area is falling within the support structure. - The gaps at the base of supports are suitable to vent small areas. - Larger areas may need you to create a gap for venting. - This \[2nd] red area is at a blind hole. - Small blind holes surrounded by thick walls may print fine. - Larger blind holes with thin walls may require a vent hole. ::: # Slices Project Analysis detects **blank slices** in the project. ::::VerticalSplit{layout="middle"} :::VerticalSplitItem ![Slice Video](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/kd1-z62KapdaO0MlBWhy3_slices-video.gif) ::: :::VerticalSplitItem **Slice Video** Projects are printed with a video of slices. Slices are cross sections through the part where UV light is projected through the liquid resin to cure it into a solid. Blank slices skip a frame in the slice video and result in defects. ::: :::: :::hint{type="info"} It is recommended to always view the slices to look for additional slice errors. ::: ::embed[]{url="https://vimeo.com/1044184960?dnt=1"} :::ExpandableHeading Video Text - Viewing slices before printing is recommended. - No blank slices are detected in this build. - A blank slice would appear as a flicker in the slices video... - ...leading to print defects in the part. - Also look for slice errors - Look for areas of white that do not belong. - This curing additional resin on the part. ::: :::hint{type="info"} Blank slices and slice errors require the STL file to be repaired in a 3rd party repair program. ::: # Islands Project Analysis detects **unsupported islands** in the project. ::::VerticalSplit{layout="middle"} :::VerticalSplitItem ![Island shown circled](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/kIfZqOtI6Wt1gX86lavIm_island.gif "Island shown circled") ::: :::VerticalSplitItem **Island Example** An island is a portion of the part that begins printing while not being connected to the platform or the rest of the part. Without supports, an island feature will fail to print intact. ::: :::: ::embed[]{url="https://vimeo.com/1044184946?dnt=1"} :::ExpandableHeading Video Text - Click the arrows to view the slices with a detected island - Look for red areas - Supports are needed here - No islands detected after supported added :::
