Hello, producers. I received a lot of questions about how I I managed to print using wood filament. So I decided to make a short video and share with you tips and tricks. I learned on the way in order to have the best possible rate of success with the wood filament without having to switch to a 0.5 millimeter nozzle. Stay around! Several people will tell you that the wooden filament should be printed with a nozzle of at least 0.5 millimeter. This is because it reduces the chances of clogging several printers that I get have a support for a 0.4 millimeter nozzle so changing the nozzle to 0.5 millimeter would not be a good option for me. But first of all, it is important to understand. The difference between congestion and clogging (pun in English) in the world of 3D printing jams usually occur because of heat-related problems. Use higher temperatures than the filament needs, and you will have chances of the melted and stopped filament in the extruder nozzle and throat on the other hand, use temperatures lower than necessary, and the filament will not have enough time to melt in the heater block, causing the filament to come back. With a temperature setting and print speed, you will have solved these problems. Congestion can also occur due to cooling fan problems if the heat sink is not as efficient as it should be. More than that if your cooling is not aimed at the print nozzle, but for the heat block, this may cause the temperature to drop. Already clogging (pun in English) in the world of 3D printing is when something is blocking the passage in the nozzle that can be debris or microfibers found in certain types of filaments. Now, for the wooden filaments, these filaments usually have 5 or 10% fine wood shavings. You end up smelling like you’re in a lumber company when you use them for your prints. It is a filament with a good texture, which makes it mix layers well. It can be sanded and also painted with wood paint becoming versatile. In addition to being fun for projects, It is not a filament that causes wear so using a copper nozzle will do. The problem with wood filaments is that they tend to clog the nozzles if the nozzle diameter is too small. In addition to the print temperature and speed settings, But they can also occur due to humidity and, most importantly, retraction plays an important role in the success rate of printing. Having too many retractions will leave a lot of loose threads. Having too many loose wires will result in clogging. Besides that, the fine wood particles can cause the displacement at the 0.4 millimeter spout. Since these particles restrict the flow of the filament and having a small piece of wood sticking out of place, causing the filament to overflow due to pressure All this together with a 0.4 mm nozzle, it can be very frustrating. Being the reason why manufacturers recommend a 05mm nozzle, which makes life easier. But that does not mean that it is impossible to make an impression using the 0.4 mm nozzle. At least not with all types of wood filaments, I’ve been making prints using wood filament for the past few months, using 04mm nozzles And the level of frustration usually depends on the filament itself. Some wooden filaments tend to be more difficult to print than others. Even with a 0.5 mm nozzle Due to the wood particles in the filament. But after watching the video from Uncle Jesse’s on filaments made me wonder if it would work with wood filaments and it would help the flow of the filament in the print nozzle. Before we start the most important thing. Before anything, I check if my filament is completely dry. Some wood filaments can be extremely absorbent. So I put them in my dehydrator for 6 hours at 60 degrees Celsius. And then I use a plug-in filter that I found the mold. It takes a few minutes to print the lock. Fold is already included in the mold. And I use a few pieces of sponge to wash dishes and I use a few drops of lubricating oil and attach the fitting to the filament. Keep in mind that there are only a few drops of oil. Impression settings are now crucial since most wood filaments are PLA based. Printing temperatures can be low. Low as 175 degrees Celsius At a speed of 50 millimeters per second on a 0.4 millimeter print nozzle and at a height of 0.2 mm layer height, I print between 185 and 205 degrees. Depending on the filament Shrinkage depends on the type of printer. If It’’s a direct extruder I’’ll be happy doing about 5 millimeters of retraction and with 0.3 mm of disengagement (coasting). If it’s a Bowden, I increase the retraction to 10 millimeters sometimes up to 12 millimeters and use 1 millimeter of coasting. Normally, high retractions like these will result in clogging, but oil helps a lot in that. So give you more freedom to deal with it. The most important thing to remember is to take the Z axis when changing print settings. This is very effective so that the nozzle does not hit another part of the model while passing from side to side. It also tends to create a lot of loose hair. My results have been good after finding the right settings for each type of filament and each printer. The final product tends to be as good as expected. I would say I have a 95% chance of success with each wooden filament with a 0.4 millimeter spout. There will be cases that will be impossible to print with some filaments. This is mainly due to the size of the wood particles in the filament. And I can confirm that I have had several such cases. Some tend to work after a lot of conviction of the slicer settings. But some will not work with a 0.4 millimeter nozzle. Sometimes I even suffer with a 0.5 millimeter tip, but this is very rare. Keep in mind that when you use oilers for filaments, You change one of the aspects of layer adhesion. Having oil around the filament makes the adhesion between the layers is not so good. It will still be good, but it won’t be that perfect as without oil. Stefan has been doing some videos on that same subject. So I suggest you take a look at his channel. All the recommendations I gave today really work, And normally when I’m using wood filament, I don’t do things with structures that take a lot of effort. So that’s it for today, Like and share the video, etc.
