![]() ![]() The point is to cut your hair the way it's worn so you can notice how and where the hair wants to fall. Then, you will do one of two things: leave your natural texture in tact and let it air dry 80% of the way, or smooth out your texture if that's how you usually wear it daily. So make sure your hair has been recently washed and is free of all products. This will ensure there is no product build-up or sebum (naturally produced oil) weighing the hair down at the roots, which would cause the hair to lay differently after it's washed. Now, with Z-offset functionalities like baby-stepping you are essentially telling the 3D printer to add "0.05mm" to where it thinks Z0, instantly adjusting the print head to bring it closer or further from the print bed for a better first layer.Ensuring the hair and scalp are clean is the key to doing this correctly. If you got good at it you could adjust it while the printer is busy printing the skirt, but often it meant canceling the print, making adjustments, and trying again. After that if you started your print and it was too far or even too close, you would have to adjust each of those screws to bring your bed into alignment. You would then adjust the bed (usually with wingnuts or thumbscrews below each of the four corners) to raise or lower the bed so it is uniformly the same distance from the nozzle everywhere across the build plate. ![]() Originally, when your 3D printer would "home" it would move to Z0, the theoretical height that the printer's bed is at. Now, when you start your 3D print, you will often have the ability to "baby-step" the first layer, that is "adjust the first layer, during a running print job, to bring the nozzle as close or as far from the bed as necessary." Overall the 3D printing user experience, along with the technology, has made major improvements. The print job was started, the printer was homed (send to the minimum or maximum of each axis), and then got to printing the supplied gcode. Don't apply the adhesive too thick! On any surface you want just enough to keep your 3D prints in place and not so much that it adds considerable thickness or that it's nearly impossible to remove a 3D print, completed or otherwise.Īdjusting the First Layer: In the far off year of 2016, 3D printers didn't really use Z-offsets. Printing PETG and its derivatives on LayerLock Powder-coated PEI doesn't require any adhesive, but printing PLA will necessitate a thin layer of PVA glue stick to keep everything locked down. Be sure to follow the recommendations for each material because you wouldn't want to use sandpaper on a glass bed, but it is recommended to use 220 grit on a LayerLock Garolite bed.ĭepending on the surface, you may even need to use an adhesive as well in order to get the 3D print to stick. Some bed surfaces can get more extreme and require you to scuff it with sandpaper or more lightly with steel wool. (99% is best) will help remove any old residue or oils left by your fingers that would hinder the ability of the freshly laid filament from sticking to the bed. Generally, a little rub down of the highest highest strength isopropyl alcohol. ![]() Once you know that the bed surface material and printing material will work together, you are ready to clean and prepare the bed for maximum adhesion. Take a look at our articles about how to succeed with any 3D printing material to gain the knowledge you need for the 3D printing filament you are struggling with and see a deep dive of the bed surface materials that are compatible. There isn't a universal bed surface material that every 3D printing filament will work with some can handle most filaments, but others are targeted for the success of specific filaments. The first layer of any 3D print is the foundation all subsequent layers are built on, which makes it important - it is also critical to remember that bed surface and material compatibility play a role in the outcome of the first layer. Whether you're a beginner or a seasoned 3D printing enthusiast, this article will help you master the art of the first layer and improve your 3D printing results. In this guide, we'll walk you through the steps to achieve a perfect first layer, covering everything from bed surface preparation to leveling methods and calibration tools. However, it plays a crucial role in determining the quality and success of your prints. If you're new to 3D printing, the first layer might seem like just another part of the process. ![]()
