Incorrect cleaning prevents the next print from adhering well. ::: :::WorkflowBlockItem **Expired resin** Check the **expiration sticker** on your resin bottle to ensure your resin is not past its expiration date. If it is, dispose of the resin and print again with a non-expired bottle. ::: :::WorkflowBlockItem **Check alignment** If you are still experiencing issues with parts consistently falling off the platform, your printer may be **out of alignment.** ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/Vho9norT3u4qYiPxtBc9W_poor-platform-alignment01.jpg) As a very basic test, you can run an an [Alignment Squares Test](docId\:eneYDJvgK9I1zhog5jjJE) or a [Z-stroke calibration test print](docId\:eneYDJvgK9I1zhog5jjJE) to see if there are any large issues with your printer's alignment. The **alignment test print** is more appropriate when adhesion is observed to vary across the build plane. The **Z-stroke calibration test print **shows adhesion is uniformly poor across the build plane. - [Alignments Squares Test](docId\:eneYDJvgK9I1zhog5jjJE) - [Z-Stroke Test](docId\:eneYDJvgK9I1zhog5jjJE) Please send the results to [Carbon Support](docId\:K86Zo5vcyN_wqJL3vdGFt) to determine if alignment may be contributing to the print failures. ::: :::WorkflowBlockItem **Still having trouble?

Check the [slice video](docId\:gfR-GoC-Irq_L9_KanC-X) to see if the palate was not supported or under supported. The proper supporting procedure can be found in [DPR 10](docId\:Y2PWbCu6_Ifchm2sdgN0R). ::::VerticalSplit{layout="middle"} :::VerticalSplitItem ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/hVSJzgLFyBC_liOnTL01x_island01.png) ::: :::VerticalSplitItem ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/NdNZttpNbj9gcgcIPwGgj_sagging01.png) ::: :::: ::::: :::WorkflowBlockItem **Palate is properly supported** If there are enough palate supports, please contact [Carbon Support](docId\:K86Zo5vcyN_wqJL3vdGFt) with a printing error. ::Image[]{src="https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/xKaNzVlq9nmdG6PCfm_Gd_supported-palate01.png" size="50" width="1041" height="791" position="flex-start" showCaption="false"} ::: :::::: ::::::: :::::ExpandableHeading ## Removable dies are not fitting ::::WorkflowBlock :::WorkflowBlockItem **Check DME settings** If using 3Shape, check to ensure that you are printing with the correct [3shape DME Settings for DPR 10](docId\:BsUOXSYRMKluviqWQk69u) supplied by Carbon. ::: :::WorkflowBlockItem Validated for removable dies Carbon has only validated 3Shape for removable dies.

A model that experiences this issue can be printed solid to avoid compromising the palate area of the part.
