The concept here is that if your mouthpiece is likely to seep a little plastic, the slower it moves during unprinted movements, the longer the plastic will have to leak on your model. However, increase that speed and the plastic does not have enough time to drip. The great thing here is that cutting machines have a configuration to speed up the mouthpiece for unprinted traffic, which is independent for printing speed. This way you can have lower print speeds for quality prints and higher non-printing speeds for exudation removal / reduction.
For both of you, watch episode 4 of this series on how to pull PTFE cold and how to fix PTFE. This is due to a poorly mounted end, cooling fan problems or simply by using a poorly made full metal end. Add cooling or reduce the emergency power for that engine. 5) Bad filament with, for example, an inconsistent diameter that freezes or even just rubs somewhere along the extrusion path.
The most popular and inexpensive 3D printers use plastic filaments. Although the use of raw materials generally reduces the amount of waste, the machines still leave unused or excess plastic in the pressure beds. PLA is biodegradable, but ABS filament is still Camping the most commonly used type of plastic. If 3D printing is to be industrialized, that by-product or other recycled plastic must be reused. Normal supporting structures for some extruder systems are designed to be easy to separate from finished printing.
As explained above, by reducing the journey you can reduce the wires. And so, by increasing the movement speed of the mouthpiece, exudation can be kept to a minimum. So if the printer can handle fast scroll movements, a higher scroll speed will help minimize chains or exudation.
This is best done when heating the mouthpiece to correct the temperature with your computer software. Make sure not to record your numbers and view your manufacturer’s troubleshooting manual that comes with the device. I’ve already talked about the importance of leveling your 3D printer bed here.
All the settings you can adjust in the “Filament” tab on your cutting machine: try one by one and see which one helps the most. The temperature of the bed has a lot of influence on how well your first layer sticks to the bed. A cooler bed generally reduces adhesion, a warmer bed increases adhesion. A common problem that we see from our customers is setting the temperature of the bed too high for the material they print with. It should remain about 10 ° C below the glass transition temperature of the filament you are trying to print.
See this guide on how to prevent your filaments from suffering moisture damage. Some experiments will be to determine which best retraction settings suit your printer and filament being used. Setting too high a retraction is a reason to hide the mouthpiece and set it too low, well, it will cause exudation and lead to chains.
