It appears you're looking for the ideal
settings for printing with TPU (Thermoplastic Polyurethane) filament on
your Anycubic 3D printer. Here's a breakdown of common recommendations
and things to consider:
Sorbothane is typically measured on the Shore 00 durometer scale and generally fallsbetween 30 and 70 durometer.For special applications, it can be cast as low as 20 durometer or as high as 80 durometer.
General Recommended Settings for TPU on an Anycubic Printer:
These are general guidelines, and the
ideal settings can vary based on the specific TPU filament brand and the
exact Anycubic printer model you have. Always check the filament manufacturer's recommendations first.
Printing Temperature:210-230°C is a common range. Some sources suggest slightly higher, up to 250°C.
Bed Temperature: 40-60°C is often recommended. Some users have success without a heated bed, especially with good bed adhesion.
Printing Speed:TPU is generally printed slower than rigid filaments. Speeds of 20-40 mm/s are typical. Some specialized "high-speed" TPUs might allow for faster printing.
Retraction:
Settings for retraction can be tricky with flexible filaments like TPU.
Some recommend disabling or minimizing retraction distance (e.g.,
0-5mm) and speed (e.g., 15-30 mm/s) to prevent jams.
Layer Height: 0.1 to 0.2 mm can help achieve smooth surfaces.
Nozzle Fan: Part cooling fan is generally recommended (ON).
Build Plate Adhesion:
Blue painter's tape is often suggested for TPU.
A glass bed with an adhesive can also work well.
Skirts are often preferred over rafts for TPU.
Extruder: A direct drive extruder
is generally recommended for TPU as it provides better control over the
flexible filament and reduces the risk of it bending or buckling in a
Bowden tube. If you have a Bowden extruder, you might need to print even
slower and experiment more with retraction settings.
Drying:TPU is hygroscopic, meaning it absorbs moisture from the air.
If your filament has been exposed to humidity, drying it before
printing (e.g., at 50°C for 6-12 hours) is recommended to prevent issues
like stringing and bubbles.
Key Considerations for TPU:
Hardness: TPU comes in various hardness levels (e.g., 95A, 90A, softer).
Softer TPUs are more flexible but generally harder to print. The
recommended settings might need slight adjustments based on the specific
hardness.
First Layer: Getting the first layer to adhere well is crucial. Ensure your bed is leveled properly.
Stringing:TPU is prone to stringing. Adjusting retraction, temperature, and print speed can help minimize this.
To get more specific settings for your exact setup:
Check the TPU filament manufacturer's website or packaging. They often provide recommended print settings.
Specify which Anycubic 3D printer model you are using. Different models might have slightly different optimal settings.
Mention the specific brand and type of TPU filament you are using.
