General 3d Printing Tips

• Make sure your printing plate is clean! Oils from your skin will cause adhesion issues for your prints. Regularly wash your print plate with a detergent like Dawn and avoid touching the surface when removing prints from the bed.
• If it's an option on your printer, always opt to level the bed before each print. If you have to perform this manually, make sure you do this after every few prints. It takes a bit of time and patience, but it's a fair trade for reliable prints.
• Ensure bed and nozzle temperatures are within the expected range for the material you are printing. Temperatures that are too high or too low will affect the print negatively by causing warping, malformed layers or adhesion issues.
• Reduce your printing speed. Slower print speed is especially important for overhangs because it gives the material more time to cool as it's deposited.
