![]() ![]() However how do you know that your real issue is revolving around exposure time? What does over exposure or under exposure look like? Below are some of the common issues associated with exposure time. When looking for guidance in resin 3D printing one of the most commonly suggested solutions would be to modify your exposure time. Prusa Slicer Exposure Time Setting Chitubox Exposure Time Lychee Exposure Time Note that all slicers denote exposure time as the same thing but bottom exposure can be referred to as burn in layers, initial exposure time and bottom exposure time. So now that we have talked about exposure times, where do we find exposure times in our slicer software? Below I have pictures of where to find this setting on three of the most popular resin slicing software: Chitubox, PrusaSlicer and Lychee. ![]() Where To Find Exposure Time Settings in Your Slicer? Very small to see with naked eye, suggested use with camera Only test to allow test of multiple exposure times at once How to Read test Github Writeup Advantages So how do you determine your exposure time? In this hobby there are several different types of exposure calibration tests to choose from each with their own strengths and weaknesses. In order to know if you are over or under exposing, read on to see signs and symptoms outlined in the exposure troubleshooting section. The trick is to dial in your exposure time, using different calibration tests. Signs of ideal exposure will successfully produce your print with a strong bond between the individual layers of the print without over curing or thickening details resulting in the loss of detail. So the leading question is “What does proper exposure look like? And how do I tell if I’m properly exposing my model?” ![]() Finding your exposure time for your unique environment will both give you confidence to experiment with new things and understand when and how your settings should change.Įxposure time can vary and be influenced based on several factors: While many companies and communities have recommended exposure time settings for your printer experience. This is arguably one of the most important parameters for resin 3D printing and is one of the most common sources of print problems for resin printing. Resin 3D printing (MSLA, SLA, DLP) is an additive manufacturing technology that utilizes photopolymers that when exposed to UV light will harden individual layers or slices in order to build on itself forming a three dimensional object.Įxposure Time is the duration of time the light source is emitting UV light to cure resin per sliced layer. Be careful not to soak for too long, as this can damage some filaments.Quicklinks: Overview, Calibration Tests, Slicer Settings, Troubleshooting, Bottom Exposure, Environmental Factors, Additional Resources Soaking your design in water can help loosen support material and make removing it more straightforward. There are products available that can dissolve 3D printing supports, and they can be a quick and easy way to remove supports, but you need to be careful not to damage your print in the process. It can be time-consuming, but it will give you a smoother finish on your print. Sandpaper or a file is also helpful, especially if the supports are not very thick.You can also use a hobby knife to cut them away from the print. One common way is to use a pair of pliers or tweezers to break off the supports.Below are other key methods for removing supports easily. The essential thing in the process is adjusting the 3D printer slicer software settings to make removal easier. There are a few different ways to remove supports from 3D prints. By avoiding these common issues, you'll 3D print with fewer headaches and better results. Supports can be a pain, but they don't have to be if you do some planning. You can fix this by increasing the infill settings or using thicker layers. Avoid this by using support structures with a larger contact area or a support material that doesn't stick as well to the printed design. You can avoid this by using support materials that are easier to remove, such as water-soluble supports. Rafts are layers of extrusion underneath an object that also help it stick better. Brims are lines of extrusion around the edge of an object that help it adhere better to the build plate. You can avoid this by using a brim or raft when printing. ![]()
