Dont use external heat if you want to preserve your prints, just change separation from the part 1mm, and Z to 90% of your layer or 70% of population, this last parameter will make weak supports, of course dont make it too weaks.

<h2>Print/material specific settings</h2>
<p>If you are printing <em><strong>too hot with too less distance</strong></em>, <em><strong>the support just fuses to the print object</strong></em>. Extra cooling, lower print temperature and support distance should be in balance to create easy to remove support structures with respect to an acceptable print object surface.

If this fails to produce easy removable supports, you can resort to changing the support distance between the support and the print object.</p>

<p>Most of the used slicers have an option to determine how much distance (in terms of layers) you want between your support and your product, you could add an extra layer as space to try out if that works better for you. E.g. the default Cura setting for <code>Support Bottom Distance</code> (which is a sub-setting of <code>Support Z Distance</code>) is the layer thickness specified in <code>Layer Height</code>. If you have a layer height of 0.2 mm, the <code>Support Bottom Distance</code> is also 0.2 mm. For the top, option <code>Support Top Distance</code> this is two layer heights, so 0.4 mm in this example. These options are visible in the expert mode, you can search for them in the search box, see image below.</p>

@BanksySan No, as long you don't make them too big, an extra layer (so 2 layers instead of 1 of in total a few tenths of a millimeter) is usually sufficient. Else tune your temperature down and increase cooling, but that might affect the structural integrity of the print.

## Print/material specific settings

If you are printing ***too hot with too less distance***, ***the support just fuses to the print object***. Extra cooling, lower print temperature and support distance should be in balance to create easy to remove support structures with respect to an acceptable print object surface. If temperature and cooling cannot be balanced to prevent fused support structures (e.g. for high temperature filament materials that cannot take too much cooling as that would result in less structural solid prints), there is an option in Cura to override the fan speed for the first layer above the support (`Fan Speed Override`). If this fails to produce easy removable supports, you can resort to changing the support distance between the support and the print object.

Most of the used slicers have an option to determine how much distance (in terms of layers) you want between your support and your product, you could add an extra layer as space to try out if that works better for you. E.g. the default Cura setting for `Support Bottom Distance` (which is a sub-setting of `Support Z Distance`) is the layer thickness specified in `Layer Height`. If you have a layer height of 0.2 mm, the `Support Bottom Distance` is also 0.2 mm. For the top, option `Support Top Distance` this is two layer heights, so 0.4 mm in this example.
