Чести проблеми и решения

Stringing

Thin, web-like strings of plastic between different parts of the printed model, often caused by moisture in the filament or insufficient retraction. Решение: Dry the filament for 4-6 hours at 50-70°C depending on the material. Increase the retraction distance by 1-2 mm, reduce the nozzle temperature by 5°C, and increase travel speed to 200 mm/s.

Warping

The corners or edges of the print detach from the build plate and curl upwards due to rapid, uneven cooling and internal thermal stress. Решение: Increase the bed temperature by 5°C, add a 5-10 mm brim around the model, reduce the part cooling fan speed for the first 3-5 layers, and apply an adhesive like a glue stick to the build plate.

Ghosting / Ringing

Repeating wavy lines or ‘echoes’ on the surface of the print, appearing after sharp corners due to mechanical vibrations at high printing speeds. Решение: Tighten the X and Y axis belts. Ensure the Klipper firmware’s Input Shaper algorithm is active and calibrated to compensate for resonance. Alternatively, reduce the print speed to 60 mm/s.

Elephant’s Foot

The lowest layer of the print is overly squished, causing the base to expand outwards horizontally beyond the desired CAD dimensions. Решение: Raise the Z-offset slightly by +0.05 mm, decrease the bed temperature by 5°C specifically for the first layer, and enable ‘Elephant foot compensation’ (0.1-0.2 mm) in the slicer.

Подходящи приложения

• Large Format Prototyping: Printing massive, full-scale functional prototypes in a single continuous piece without needing to slice the model into smaller, modular parts, leveraging the printer’s large build volume.
• Manufacturing Jigs and Fixtures: Producing custom, heavy-duty alignment templates, holding fixtures, and tools in low volumes (1-100 units) to optimize assembly line workflows.
• 1:1 Scale Props and Armor: Creating full-sized helmets, armor sets, and props for cosplay or film production in a single print, reducing post-processing and assembly time.
