Low Temperature PCL Filament Polycaprolactone 3D Pen Filament 1.75mm 1KG 2.2LBS 3D Printing Pen Refill for 3D Pen,White ,1.75mm - IKDK, Caliper-Micrometer-Pro

• 【Low Temperature PCL】Environmentally friendly low-temperature material, degradable. As a biodegradable material, it is very strong at room temperature and softens when the temperature reaches 60°C. It is the best choice for 3D printing refills 【Stable Dimensional Tolerance】Minimum tolerance and low warping to ensure consistent feeding and stable prints, no clogging, no bubbles, extremely high successful rate, resulting in an outstanding surface finish and are highly precise. 【Tangle Free & No Plugging】Full 1KG 3D printer filament reel, perfect roundness and very tight diameter tolerance, does not overlap or tangle, less stringing, strong layer adhesion. Melt well, feed smoothly and constantly without clogging the nozzle or extruder. 【Safety Material】Compared to 3D pen filament refills ABS/PLA 1.75mm, PCL filament is no odor, non-irritating when infused into 3D pen. It is the 100% safe option for children's crafts and adult arts. 【Vacuumed Sealed Packaging】1KG Spool Low Temperature PCL Filament comes in a sealed vacuum bag with a desiccant bag, easily keep your 3D printer filaments at an optimal storage condition and free from dust or dirt before opening the vacuumed sealed packaging.
