As PVA doesn't suffer from scarring or adhesion issues due to its water-solubility, this value has been set to 0 for PVA profiles. Stair stepping is intended to reduce the adhesion between support and the model, where the support rests on the model, and to reduce scarring. In preview mode with ‘Line type’ selected, support material will render with transparency so you can easily see what’s being supported. The "Infill only" checkbox has been changed to a dropdown selection: “Infill mesh only” or “Cutting mesh”. smartavionics has contributed a new setting that applies an offset to all holes on each layer, allowing you to manually enlarge or contract holes to compensate for horizontal expansion. A tooltip gives extra information about which scripts are enabled for quick and easy inspection, so there's no need to open the post processing dialog. The number of enabled post processing scripts will now display as a badge notification over the post processing scripts icon. fieldOfview has contributed an ease of use improvement to the post processing plugin. Due to popular demand, version 4.6 expands the range of Engineering Intent profiles to include more of the Ultimaker material portfolio: PC, Nylon, CPE, and CPE+. In version 4.4 we introduced Intent profiles for the Ultimaker S3 and Ultimaker S5 which allow you to start prints at the click of a button without a lot of configuration steps.
