When the hotend travels over the model could ooze material, leaving strings of material in undesired places. The way the travel movements are configured is crucial to getting cleaner results. Disable the purge tower, this will save you printing time and material that can be used for other prints. The purge tower helps to purge this worn-out filament while keeping the printed part clean.įor prints with a lot of tool changes, this is not necessary, as there's not going to be enough time for the filament to absorb moisture or crystallize. If your Silicone clothes are broken, feel free to get in contact with your distributor or our sales team to replace them.įor prints that have a small number of tool changes, you should leave the purge tower activated, as the filament that's loaded in the idle printhead is kept at a high temperature, it will absorb more moisture than usual, and crystallize inside the nozzle, thus making a low-quality print.These little wipes play a huge role in this, they are a component that tends to be overlooked and it is important to have them in the best conditions possible to keep the nozzle clean during the Dual prints.Ĭheck that they are not broken and raise them just a bit so they clean the nozzle thoroughly. How to improve the quality of the dual printsĪll of our printers have purging buckets and on top of them, you'll find the Silicone Cloths, these are in charge of cleaning the nozzles. Checking the calibration of the X and Y axis can help to solve the problem. Calibration issues: when the materials are not aligned due to a calibration issue, may cause the colors overlaps.Stringing: fine strings left around on the print can contaminate each material in the piece.Some common printing quality issues are related to the color overlaps in the Dual prints: However, in models where is necessary to change materials a lot of time, is necessary to adjust some parameters to get cleaner results. The independent printheads have the advantage of being cleaner than other dual-extrusion systems, as they are wiped before each head comes out to print.
