Support failures happen at the support tip (see next point) or randomly during in the support structure. Most parts need to be printed on supports.
– Increase the exposure time of the regular layers.(don’t reduce it so much that adhesion failures occur) – Reduce the exposure time of the bottom layers.Sometimes the regular have difficulties to adhere to the bottom layers. The exposure time of the bottom layers is higher to get a good adhesion to the build plate. Most parameters are set in a way that you can control the exposure time of the bottom layers and of the regular layers. – Decrease the lift speed and retract speed of the bottom layersĪll these modifications will help in getting a stronger adhesion to the build plate and reduce the chance of failure.Ģ) Regular layers delaminate from bottom layers.– Increase the wait time before lift on the bottom layers.– Increase the bottom layer exposure time.A badly calibrated build plate will always result in adhesion issues. Before looking into the settings, re-calibrating your build plate as good as you can. This usually means that the first layer did not stick well to the build plate and failed right away. In this case you can increase the bottom exposure time with 10-20% and it is usually fixed.Ī third and most common scenario is that nothing is attached to the build plate, and that on the bottom of the resin tank is a few millimeters of solidified resin. If the first part of your STL file is in the resin tank, then it usually means that the part delaminated from the build plate halfway the build. If it doesn’t show any light, contact the hardware manufacturer. It is worth to reset the 3D-printer and do an exposure test. If there is no solidified part on the bottom of your film, then there is likely something wrong with the light source of mirror / DLP module/ LCD screen. Here you have to check how thick / big the part is that is stuck to the bottom of the build plate. Not even a thin layer of plastic is attached to the build plate. One of the most common issues is if a part doesn’t stick to the build plate at all. – Keep the resin temperature at least at room temperature (20C / 68F).There can be small plastic parts in the resin tank that can destroy the resin tank or part of the printer Additionally, it is always advised to filter the resin after you had a print failure. It is good to know that there are already many pre-settings available for Liqcreate resins.
Most common 3D-printing fails and how to solve themīefore focusing on the printing issue. If you don’t like reading, Hiro Creations shared a video on his tips and tricks how to solve these problems. In this article we explain the most common resin 3D-printing defects and how to solve them. This is due to the many different factors involved in the 3D-printing process. Resin 3D-printing is more complicated than many other 3D-printing techniques.
