Preparing your 3D printer before printing

Perfect First Layer

To have your printer calibrated well is the most important to achieve the best results. It is wise to calibrate you printer every time you assemble it or after changing the nozzle. When printing with some nice materials like Matte PLA on a perfect Z-Level, you can get perfect top layers which almost don’t seem to be printed by FFF.

At first, your print bed should be aligned with the print head and you can find those instructions in you 3D printer manual. A lot of printers use calibrating sensor to help you with aligning the bed. But you must not forget that to set the Z – 0 level correctly.

Calibrating with a paper

The most elementary way is to calibrate your z-level is with a piece of regular paper. You can also use it for aligning the whole bed.

There should be a space between the bed and the nozzle to fit the paper. When you are at Z-Level at 0 and you put the paper under the print head, you should be able to move the paper, but you should feel a light friction. When the paper hardly moves, the level is too low and if there is a space for two papers, the level is too high. 

You can also adjust the z-level depending on what the first layer looks like. Layers should be connected perfectly with no gaps or overflow. When there are gaps between the layers, the level is high and when you see overflowing material, the level is low. And if the print is not visible at all, the level is way too low 🫣. 

On very basic printers it is very easy to adjust the bed during the print with slightly turning wheels or screws.

Important note: when printing watertight prints, it is good to have a position a little lower or correct along with a flow setting up to 100% where it is good to see the bits a little overflow. It makes you sure, there are no gaps between layers.

Adhesive Spray  

We recommend to use adhesive spray on you bed to prevent warping and tearing your print. sometimes the print may come loose and fall off after a few hours of printing, which is very sad. We are always using 3DLAC spray and together with the right bed temperature we never had a problem.
