A mesh is “super refined” when the total number of triangles in the STL mesh is greater than required. This does not cause errors during 3D printing, but unnecessarily increases the Camping size of the STL file, making it difficult to use. Small details displayed by an over-refined mesh are generally not printed 3D because they exceed the capabilities of most systems .

The PLA can experience tear and low separation problems if it prints too cold. Try to increase the print temperature in steps of 5 ° C until you successfully attach the layer. The PLA is often printed with 100% coolant fans anyway, so if you look at how it gives priority, it suggests that the print temperature is too high. We always recommend starting and moving forward at the bottom of the proposed temperature range. The high-quality pure PLA is better printed at 200 ° C or less

If you are already 100%, you can make sure that all camera doors are open or add external fans on the printer side. It may not be suitable for all materials, consult the manufacturer / seller. Fibrous prints or cases of overhangs are generally the result of over-hot printing or insufficient cooling. Often the object to be printed can be rotated in bed, so that fewer supports are required. Or you can split the model in half with a flat cutting tool and completely avoid the supports.

If you have a lot of strings, you will certainly melt at too high a temperature. Remember that all materials have a temperature range in which they can be printed, so try to lower the temperature and bring it closer to the manufacturer’s recommended lower limit. If you are already using a very low temperature and still have a cord, check the following points. PETG especially tends to build up in your mouthpiece, build up during printing and eventually drip. This (and sometimes excessive adhesion to certain building board surfaces) is why we recommend not to crush your first layer when printing with PETG

The second option is extremely useful if your part is a single solid model. For example, our pyramid is a single sturdy part that should not have multiple pieces. In this case, you can enable the option “Combine all diagrams in one solid model”. While this option doesn’t work for every part, it is a very powerful tool that can help repair models that are not airtight solids.

An increasing dimensional error is usually a sign of wrong steps / mm settings for your X, Y or Z axes. This can be calibrated and corrected in the firmware or in the printer menu. These variations in the layers are often the result of temperature fluctuations. It is best to test some linked prints while running surveillance software. For example, the free and open source Pronterface to map the exact temperature on the mouthpiece during printing.

The first 3D university printing service started in Washington, DC and has experience in the management and coordination of printing works. Witte has been recognized by Ultimaker as an educational pioneer in 3D printing Normal supporting structures for some extruder systems are designed to be easy to separate from finished printing. Therefore, they intentionally leave a small space between the supporting structure and the actual model above it.

If your mouthpiece rattles over the remaining wreck of your previous prints, it will start to bounce and introduce vibrations into your printer depending on how stiff your baby carrier can be. This is one of the most common problems with many 3D printers. If your adhesion is missing, it can end with a distorted impression, or no impression, plus a huge confused filament debris on your bed (p. E.g. Green print ‘bird’s nest’ can be seen here). High-resolution desktop stereolithography 3D printers are fast and cost effective tools for producing high-detail models with smooth surface finish. When closing the gaps, Netfabb will prefer to fill the open holes that require more manual repairs. Tap the Select Surfaces icon on the main toolbar and select the entire hole, then press Delete.

Alternatively, use the Brush Selection tool and use Ctrl + Scrollwheel and the More / Less buttons to change the size and selection of the brush. Using the selected triangles, choose the selected triangle icon Delete and manually add the missing triangles, as well as some bridge triangles using the Add Triangles button. Operation Repair → Close all holes complete the mesh repair task. Finally, we can choose to refine the mesh with the Mesh Edit → Remesh command that recalculates the model based on a Target Edge Length parameter. Check the Edge option to optimize the model integrity around sharp edges. The following section tests all five STL repair tools using a complex 3D model of a coating hook with several major errors, including holes, openings, intersections and floating triangles.
