3D Printing - Materials for 3D Printing

APrint speed 80 mm/s, nozzle temp 210°C, retraction 0 mm

BPrint speed 60 mm/s, nozzle temp 190°C, retraction 6 mm

CPrint speed 40 mm/s, nozzle temp 250°C, retraction 5 mm

DPrint speed 25 mm/s, nozzle temp 220°C, retraction 1 mm

Step-by-Step Solution

Solution:

Step 1: Evaluate print speed and temperature for TPU wearables
Low speed (around 25 mm/s) and moderate temperature (220°C) help print flexible, durable TPU parts.
Step 2: Assess retraction setting
Minimal retraction (1 mm) reduces stringing and filament jams common with TPU.
Final Answer:
Print speed 25 mm/s, nozzle temp 220°C, retraction 1 mm -> Option D
Quick Check:
Slow speed + moderate temp + low retraction = best TPU print [OK]

Quick Trick: Slow speed, moderate heat, low retraction for TPU wearables [OK]
