Hey, I’m out from a directors and today. I’m going to show you how to succeed with PLA currently POS demos, common 3d printing material with ABS coming in a closed set. Now, what makes PLA so special is how easy it is to print with. Once you fine-tune a few small details, the first time users or for veteran users 3d printing with. Pla is a breeze. It’s awesome for anything. You want printed fast? Anything with vibrant colors or you can print most of these things on the wall. The rifle is PLA! The astronaut, the power armor, the naval hand. PLA comes in a variety of colors. The print with school use it. No fumes, no warping all around. Pla is a super evening material when you try to 3d print. Pla, there’s a couple quick things that could make or break your successful print, so let’s dive into what it takes. The first tip is to make sure your first layer is right now. Different perimeters have different techniques for actually leveling the bed. So your techniques you may need to adjust. According to that for most printers, it’s something like either three screws or four screws on the corners of the bed or in front. It’s back and all you have to do is move the nozzle over the screw. They can slip a paper and put it underneath the nozzle and then gently turn the screw until there’s a very slight resistance in the nozzle of the paper and the bed and there you’re going to gently pull on it, so you get right for amount of resistance and then move the nozzle to each point. Once the resistance is about the same on all of them, You’re good to go. The point isn’t to get super tight and all of them or super loose, just a consistent level across all of them from there. You go in your slicer and just wish the opposite. If you find that starting a print, it’s too close or you can try and mess with it while it screaming the skirt and adjust the screws at that point. That’s what I personally do. You can use whatever technique You find works best for you. Other printers automatically a little bit, so something like the old but has six or the old maker three. Those have their techniques for leveling the bed. And with that you not to worry about anything. Just watch it start to make sure it hears the bed and you’re good to go. You can also software level any printer by using matter control within matter control, There’s a leveling feature where you can pick three points on the bed and it’ll walk you through the steps to level it. It’s basically the same process as if you were turning the screws, but with this, even if your bed is at a full angle, it’ll be able to adjust for that and print on that angle the entire time, so this is just some different techniques for how to level the bed, but follow the instructions that came with your printer because each printer does have is own set of rules Now that the bed is level. You need to actually make sure that the nozzle is at the correct distance from the bed. Do that all you need to do is watch it. The skirt is laid out. Are the lines super close to each other and actually lifting each other apart? Do not look so close. Are the line far enough apart where you can see a distinction between each pass your novels too far, and these are things that you’ll gain and learn as you print but to start off. Just make sure that the lines are just a little squished. Into each other. We’re not smearing out the sides of the novel passed by. You can also use matter control to baby step you see, offset, so it will move the nozzle in small increments away from the bed or post it to the bed. If you find that, it wasn’t tuned right when you turn the screws. In that case, all you have to do is just gently move the nozzle up the board down and point out two millimeter increments until you find that the best adhesion is at the right level tip number, two dedication and print bed services. If you don’t obligated that, don’t worry. POA is one of the few 3d printing materials that you don’t need a heated bed to print on in that case. All you need is some blue painters tape doesn’t matter. The branch is blue painters tape, and all you have to do is put it on the bed and make sure if you add each strip. They flood up against each other and don’t overlap but not too far apart. Any of those differences will contain difference. See on this one that there is, There’s a distinct pattern on the bottom, and that’s from the blue tape. So if you don’t mind that, and you’ll all be heated bed that will work perfectly for you. You will need to swap out some of the tape. As time goes on from either gouging the tape as you’re removing prints or it just doesn’t stick as well really easy to take it off. Put on new strip, and you’re good to go. If you do have a heated bad kisser, you can do just pronounced. It tastes like you were without a heated bed and just don’t turn the bed on model. We’re fine or if you want to get that ultra glossy finish that glass is known for. I have do is turn off the bed to drop seven Celsius and turn down the frame speed to about thirty millimeters per second and just make sure that first layer is really squished and layered, properly as a first layer or just keep an eye on them too low of a print bed temperature and the corners will work to Hod. And you will get a very similar problem. 70 cells. This is a good number. If you don’t mind not having the glossy surface on the bottom of your print, you can use some. Elmer’s glue, stick, just regular school glue, stick it on the bed and crosshatch pattern from one point or the other to one half this way, one cut that way, and then your prints should stick. So this is very helpful in trying to make sure that your prints stay on the bed, Not too concerned surface. Finish on the bottom, and it’s really easy to clean off with just some water and some sink coming off or it’s either renu-i’t. Just what a paper towel and wipe it down and you can keep training on it again. Tip number three, calibrating the print temperature for PLA. I generally print with 200 degrees Celsius for the printhead and 70 degrees Celsius for the bed. Now this will change depending on the brand, the filament color any additives in the manufacturing process, so it is something we’ll need to calibrate, and there are a variety of calibration models out there from calibration cube subtraction tube test to full test pieces language. One you like best, which covers the features you want to calibrate for and just find symptoms. That’s what you’ll have to do is neither razor strop five degrees down five degrees, and that’s when you’ll start to be able to do and there are many guys out. There dedicated to each specific problem you may find. But in general 270 are great set six number four. How to change villain, one of the earliest mistakes? I made when 3d printing was changing filming. I thought that I could just pull a filament out of new and end and be done with it. What I actually need to do is make sure that the temperature of the filament is hot enough bricks to be able to command novel. Because what happens is it melts and then cool in the nozzle, it foams on plug, but what you got to do is heat up a novel. This engage the retention on extruder, which came to be done the lever and some printers or some other system that you can be dipping gauge what we do, heat it up to no printing temperature. Pull it out, Put the new one in re-engage. The extruder nation start printing now. If you’re trying to avoid color mixing what you can do is set the extruder to 90 Celsius, gently pull on the filament and then turn off the heat to about high and 50 at some point. When you can feel the filament give and you can yank it out, pulling out all the old guns and have a nice, clean extrusion when you put in a new filament system resources, be sure to regularly clean your shooter gear. There’s a small gear inside your extruder and that gear presses up against your filament and pushes it through using the small key comics. Now, if the tension is too tight, it really chews up that filament, and then it fails to extrude or if it’s just being regularly used. It fills up a little bit to you now. The easiest thing to do is a toothbrush or a small, wiry brush to brush out the gears. It’s turning it to make sure it’s all clean, and once that’s done, It’s good to go for another couple months. The thing is to just make sure that when you see, it’s getting dirty, you just see that there’s filament dust all in the extruder. Just clean it out as a refresher in the general meaning. If you aren’t able to extrude at all, your nozzle may be clogged. And in that case, we have another video on how to unclog your noggin. So be sure to check that out. Add that to your knowledge base for when it happens because it will happen. It happens to me, happens to the best of us. It’s just part of 3d printing and that’s it. It’s a lot of information to process, but all together. You should have something to work from so you start printing. Pla the start printing PLA successfully.
