Refer [here](docId\:pPm8gmeGCY_0fkFwgTCyj) for more tips. ## Process and Hardware Checks If any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved. :::ExpandableHeading ### Platform For new platforms, the factory coating may make parts difficult to remove. Use acetone wipes or an acetone soaked blue towel to scrub off the coating. ![New Platformsd](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/J58UAqAqn9ox-xjwUZv0N_image.png) ::: :::ExpandableHeading ### Release Film Release film reduces adhesion. If you experience chipping or gouging due to over-adhesion, try printing the build using release film. ![Release Film](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/Rd5dakaYT9SQiREh2RD0V_image.png) ::: :::ExpandableHeading ### Process Technique - Review standard procedure for [removing parts from platform](docId\:AvN2rNsLSHhmUz9rbYkmN). - Maintain scraper contact with platform at all times. - Proceed slowly. - Try removing parts from the platform with a dead blow hammer and scraper, when too much force is needed with the scraper tool alone: (as shown below) - Align the scraper blade with the part. - Tap back of the scraper tool **LIGHTLY** with the hammer. - Make sure to keep blade against platform at all times. ![Deadblow hammer](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/wNFqX0-qeCDAOiwYja724_image.png) ::: ## Print Preparation or Part Design Adjustments The following solutions will address print or part-related causes of the defects. Choose among the suggested actions below and select the best approach for your application. Usually only one type of adjustment is needed. :::::ExpandableHeading ### Orientation ::::VerticalSplit{layout="middle"} :::VerticalSplitItem Change the orientation to place a smaller cross section on the platform. ::: :::VerticalSplitItem ![Orientation](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/9YjL037UEz_lFezqVNS2Y_image.png) ::: :::: ::::: :::::ExpandableHeading ### Supports ::::VerticalSplit{layout="middle"} :::VerticalSplitItem Support the part off the platform. - Supports will provide a smaller cross section on the platform - The scraper tool used to remove the part from the platform will not touch the part, protecting it from damage. ::: :::VerticalSplitItem ![Supports](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/QePQB-W8rxAZG0fnwb5_7_image.png) ::: :::: ::::: :::::ExpandableHeading ### Design ::::VerticalSplit{layout="middle"} :::VerticalSplitItem Redesign the part with fillets or bevels at the platform edges. ::: :::VerticalSplitItem ![Design](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/W1SJFJrSiXymcqV_Yyb_u_image.png) ::: :::: :::hint{type="danger"} **Use extreme caution with this troubleshooting option.** A common cause for the inverse defect, [Under-Adhesion](docId\:DAbqNXb4KnG1eeiClRzqF), can be from this type of design. This is best utilized for rigid resins when the cross section on the platform is large and other solutions are not viable. ::: ::::: :::ExpandableHeading{isOpen="true"} ### Print Plan Adjustments Reference [Print Plan Adjustments](docId\:NxUK0dltz_vemEAU0DIpN) for guidance on the following parameters: Refer to guidance for **Over-adhesion.** [5 Exposure Parameters](docId\:nunXRrM4bWbawUQk0FrDt) *To reduce adhesion* - Exposure Timing Parameters - Base Exposure Multiplier - Brightlining Parameters *All four parameters must be specified* - Brightline Interior Exposure Time - Brightline Exterior Exposure Time - Brightline Border Thickness Pixels - Brightline Outer Borders ::: :::hint{type="info"} If problems persist, please reach out to [Carbon Support](mailto\:support@carbon3d.com). ::: # Explanation & Causes ## Explanation ::::VerticalSplit{layout="middle"} :::VerticalSplitItem - Part may be strongly adhered to the platform. Reference also [Over-Adhesion](docId:6k62sHy9n_S4Srwm6PAZc) - Poor removal technique. - Using scraper to pry part off platform. - Not keeping scraper in contact with platform during removal. - Using too much force with deadblow hammer. - EPX is more susceptible to chipping due to brittleness. ::: :::VerticalSplitItem ![Over-adhesion](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/mGSMfcgANvxUOHwRrUYeT_jedvvto33ouxqcox-d8lhpfjx-d3k-n5x.jpg) ::: :::: ## Causes ::::VerticalSplit{layout="middle"} :::VerticalSplitItem **Post-Processing** How the part is **handled** in post-processing is causing the defect. ::: :::VerticalSplitItem ![Post-Processing](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/krdNaFJJBdBiNamx73e7u_image.png) ::: :::: | Root Issue | Problem | Why Defect Presents | | ---------------- | ---------- | ------------------------------------------------------------------- | | Platform Removal | Aggressive | Resins are delicate in the green state and require gentle handling. | ### Print Preparation or Part Design ::::VerticalSplit{layout="middle"} :::VerticalSplitItem How the part is **oriented**, **supported**, or **designed **is causing the defect. ::: :::VerticalSplitItem ![Print Preparation or Part Design Cause](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/LhaBjVT_Yxhp03FPtHLyF_orient-and-support-quick-view-v0101-xxs.gif) ::: :::: | Root Issue | Problem | Why Defect Presents | | ------------- | ----------------------------------- | ---------------------------------------------------------------------------------------- | | Over-adhesion | Large cross section on the platform | More surface area to adhere the part to the platform at the higher base exposure levels. | ### Hardware ::::VerticalSplit{layout="middle"} :::VerticalSplitItem ::Image[]{src="https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/cNMDprn99RIqCfoLiaEF4_hardware-xs.png" size="80" width="738" height="600" position="center" alt="Hardware" showCaption="false"} ::: :::VerticalSplitItem The printer, cassette, or platform is **dirty** or requires **maintenance **to resolve the defect.

In doing so, adjustment may both **prevent or cause defects**. Below are adjustments that can cause this defect. ::: :::: | Printing Stage | Parameter Type | Type of Adjustment | Why Defect Presents | | -------------- | --------------- | ----------------------------------------- | ------------------------------------------- | | 5 Exposure | Exposure Timing | **Increase** | Adhesion is increased with more UV exposure | | 5 Exposure | Brightlining | **Increase** | Adhesion is increased with more UV exposure |
