Tips:

Calibrate your 3D printer regularly to ensure that the extruder is applying the right amount of pressure and that the print bed is level.

Use supports when printing complex geometries or overhangs to prevent the plastic from sagging or collapsing.

Use a brim or raft when printing objects with a small footprint to improve adhesion to the print bed.

Experiment with different infill patterns and densities to find the right balance between strength and weight for your project.

Use a slower print speed for complex or detailed prints to improve the overall quality.

Use a layer cooling fan to help the plastic solidify faster and reduce the risk of warping or other defects.

Clean the print bed and nozzle regularly to remove any debris or excess filament that could affect the quality of your prints.

An old trick is to use painter's tape or another adhesion aid on the print bed to improve the adhesion of the first layer of your print.

Stunning hotends! Wow.

- de3dprintman

This was the only hotend that could keep up with my printer, and will happily extrude as much plastic as my fans can cool - I'll be putting one on all my printers.

- Alice M

J-head Classic is the only true PLA friendly hot-end. Bio-based is the future material. I've been using J-head hot-ends for 10 years. Please keep it going.
