Formlabs conducts extensive validation of new print settings before releasing on PreForm. All settings are validated to Formlabs recommended refresh rates.

Details on Default v5.3 settings

If you switch to Default v5.3 from previous settings, you may notice the following:

Z-axis warping and accuracy

The new Default setting significantly reduces the warping that occurs on long parts oriented along the Z-axis. With Default v5.3, warping is reduced by upwards of 50% to previous settings. As a result, the maximum part height when printing with this setting is 294.1 mm, approximately 1.4 mm shorter than previous print settings.

Surface dimpling

The rate of dimpling on parts printed with Default v5.3 is comparable to that of Legacy v4.1, with no significant differences. Tuning the printer’s bed temperature helps reduce the likelihood of dimpling, but some geometries are still more susceptible to dimpling, particularly spheres. If your parts are more prone to dimpling, contact Formlabs Support for more advanced troubleshooting support.

Print speed

The new Default v5.3 settings maintain the same fast and efficient printing speed as the previous Speed Optimized setting.

Print cooldown

While printing times remain unchanged compared to Speed Optimized settings, Formlabs recommends letting your parts cool for 30% longer for optimal results. This is twice the cooldown time of Legacy v4.1 settings. This cooldown can happen outside the printer, freeing it up for the next print.

Due to the increased efficiency and fast print speed of Default v5.3 settings, the powder cake will remain noticeably hotter after cooling for the same amount of time as parts printed with other settings. Take extra caution when unpacking parts, and refer to published print cooldown times in PreForm as a helpful guide for when your parts can be unpacked. Premature unpacking can cause parts to warp.

Bed Temperature Offset

Customers who had previously applied a bed temperature offset to their printers should remove it and reset the printer back to nominal bed temperature prior to printing with the Default v2.1 settings. After printing with the Default setting, customers can work with Formlabs Services to modify the bed temperature if needed based on part quality. A previously-set bed temperature offset used on a different set of settings is not applicable when printing with Default v2.1 settings.

Part depowdering

You may notice harder Surface Armor more frequently than on the Legacy v1.2 settings. To resolve this, first try reducing the bed temperature of the printer. If issues persist, reduce armor exposure by modifying the Armor Laser Power parameter using the Print Settings Editor. Reduce the value in 10% increments, testing between each change.

Recoater artifacts

Due to the faster printing speed of Default v2.1, you may notice more print-related debris around the build chamber. Vacuum the print enclosure and around the top of the build chamber between each print. Otherwise, the debris may be dragged across the print plane by the recoater, causing print defects or errors.

The new Nylon 11 CF Default v1.2 setting addresses part warping and accuracy in the Z direction and poor finish on vertical surfaces. When using these print settings, you should expect to print more accurate parts with fewer instances of poor vertical surface finish.
