![]() Hairspray: A light spray of hairspray on the build plate is a popular method of aiding adhesion to the bed. Be sure to stick your tape down evenly, ensuring that there are no overlaps in the tape that could cause high spots in your otherwise level build plate. It’s easily applied and even easier to remove after a print. Painters Tape: Blue painters tape can serve as a great temporary solution to increase your part’s adhesion to the build plate. If you’re looking for a more temporary solution or are just in a pinch and need something to stick to the build plate, there are a few temporary solutions to the problem: After printing, allow the sheet to cool and peel off the sheet along with the offending debris (now stuck onto the 3D printed sheet). When faced with even more stubborn, melted on 3D print material that simply won’t budge, printing a 1- or 2-layer thick sheet, the size and shape of the printer’s entire build plate in a material like PETG can do the trick. For other advanced, composite build surfaces such as our Ziflex build surfaces or the stock build surfaces on printers such as our Creality CRX and CR-10 PRO’s a light scrape with the scraper supplied is often enough to removing stubborn, stuck on debris. For build surfaces such as PEI build surfaces, a light sand with 600+ grit sandpaper can remove any protruding debris, gently roughing up the surface of the PEI and greatly aiding in adhesion. A quick wipe of glass build surfaces with common, household glass cleaners (ammonia based) like Windex can be an effective way of removing print residue. While these generally don’t present a problem in small quantities, they can pose a problem with adhesion if allowed to build up as they can prevent your first later from properly adhering with the build plate. Loose debris such as dust or un-removed support material from previous prints inevitably coat the surface of your print bed over time. Lowering the fan speed or setting fan speed to 0% for the first few layers will ensure the molten filament has more time to flow and conform onto the surface of your print bed, aiding in adhesion. If you have the ability to do so, printing the first two layers slightly hotter (80☌) will aid in print adhesion. We recommend printing PETG with the heat bed temperature at around 70-80☌. Increasing the heat bed temperature allows printed layers to cool slowly decreasing the amount of contraction experienced at the base of your printed model. This contraction in turn causes stress, pulling the edges inwards. As it cools, it contracts along the lateral surfaces. ![]() Increase bed temperatureĪfter leaving the nozzle, molten filament solidifies. This minimises corners lifting and helps keep the print stuck onto the bed. This increased surface area results in increased adhesion to the bed, which is often enough to keep the corners of your print stuck down. Printing with the brim option turned on increases the total surface area of the first layer. An uneven bed is usually the most common culprit when it comes to poor part adhesion. First check if your bed is manually level as per your printer's instruction manual.
