PLA Settings for Two Trees SK1

Temperature Settings

Start with the nozzle at 205°C and the bed at 55°C. If you see poor layer adhesion, increase the nozzle temperature by 5°C increments. If you experience stringing, decrease the nozzle temperature by 5°C. For the first layer, you can increase the bed temperature by 5°C for better adhesion, then let it drop back to 55°C for subsequent layers.

The PLA filament has a recommended nozzle temperature range of 190-220°C and a bed temperature range of 50-60°C. The Two Trees SK1 supports nozzle temperatures up to 300°C and bed temperatures up to 110°C, which fully covers the recommended range for this filament.

Speed & Quality

The Two Trees SK1 supports high-speed printing at up to 700 mm/s. For PLA, we recommend 100-300 mm/s for general printing. Start with the lower end for quality-critical prints and increase for draft prints. Always print the first layer at 25-50% of your normal speed for better adhesion.

For quality-critical prints like miniatures or display pieces, reduce the speed to 100 mm/s and use a 0.12-0.16mm layer height. For draft or rapid prototyping, you can push the speed to 300 mm/s with a 0.24-0.28mm layer height. The standard 0.2mm layer height at 200 mm/s provides the best balance of speed and quality for most prints.

Bed Adhesion

PLA adheres well to PEI sheets (smooth or textured) without any adhesive. If using a glass bed, apply a thin layer of glue stick or hairspray. Clean the bed with isopropyl alcohol (IPA) before each print for consistent adhesion.

Common Issues with PLA on Two Trees SK1

Here are the most common problems you may encounter when printing PLA on the Two Trees SK1, along with proven solutions:

• Stringing: Lower nozzle temperature by 5°C and increase retraction distance slightly
• Warping (rare): Increase bed temperature to 60°C, use a brim, and clean the bed with IPA
• Poor layer adhesion: Increase nozzle temperature by 5°C and check if filament is wet
• Brittle prints: Filament may be old or moisture-damaged; try drying at 50°C for 4-5 hours

Tips for Best Results

Follow these expert tips to get the best possible prints with PLA on your Two Trees SK1:

• Print a temperature tower to find the sweet spot for your specific PLA brand
• Store filament in an airtight container with desiccant when not in use
• Clean the bed with IPA before every print for consistent adhesion
• Use 100% cooling fan from layer 2 onward for best overhangs and bridging
• PLA is great for prototyping but avoid leaving prints in hot cars or direct sunlight

Support Settings

For prints requiring supports with PLA, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.
