Чести проблеми и решения

Stringing

Thin web-like plastic strands between printed parts, often exacerbated by the long Bowden tube setup typical of Delta kinematics. Решение: Dry the filament for 4-6 hours at 50°C. Increase retraction distance by 1-2 mm, lower nozzle temperature by 5°C, and increase travel speed to 200 mm/s.

Layer Shift

Horizontal displacement of layers mid-print, frequently caused by loose belts on one of the three vertical Delta towers or skipped stepper steps. Решение: Evenly tighten the driving belts on all three towers, ensure pulley grub screws are secure, check linear bearings, and reduce print speed by 20%.

Bed Adhesion Failure

The first layer fails to stick to the circular build plate or the part warps and detaches during the printing process. Решение: Clean the build plate thoroughly with Isopropyl Alcohol (IPA), apply an adhesive like a glue stick, and meticulously fine-tune the Z-offset.

Подходящи приложения

• Tall Prototype Fabrication: Utilizing the extended vertical Z-axis volume typical of Delta printers to create tall, continuous models without the need to split them into parts.
• High-Speed Draft Printing: Leveraging the lightweight print head (enabled by the Bowden extruder) and agile parallel kinematics for rapid visual prototyping.
• Robotics and STEM Demonstrations: Using the visually engaging Delta Cartesian kinematics to teach students about coordinate geometry, robotics, and additive manufacturing.
