3D PLA 1.75MM BLUE Plastic 3D Printer Printing Filament, Dimensional Accuracy +/- 0.04 mm, 1KG 2.2LBS <span class="a-text-bold">Level bed</span>- Having a level bed is critical. <span class="a-text-bold">Higher temperature</span>- As a rule of thumb, an additional 5 is recommended. <span class="a-text-bold">Lower speeds</span>- 30% or 50% of the normal speed is recommended. <span class="a-text-bold">Correctly calibrated extrusion rates</span>- it is important to have a well-calibrated extrusion rate as recommended in calibration. <span class="a-text-bold">First layer height</span>- It is recommended to raise the first layer height to match the diameter of the nozzle. <span class="a-text-bold">Bed material</span>- PLA is more forgiving and works well on PET, Kapton, or blue painters tape. <span class="a-text-bold">No cooling</span>- Keeping the fan turned off for the first few layers. <span class="a-text-bold">Fatter extrusion width</span>- The more material touching the bed, the better the object will adhere to it, and this can be achieved by increasing the extrusion width of the first layer, either by a percentage or a fixed amount. Made from 100% Grade A Virgin Raw Materials from Natureworks USA. Controlled using Non-Contact Laser Diameter Gauge: Rapid, precise and repeatable measurements to minimal dimensional tolerances. New Non-Brittle Formula: Naturally brittle plastics such as PLA can now be used with confidence knowing that the filament will not brake during a print job, while still inside the printer or just sitting in storage. Ideal for High Resolution Prints: Our filaments will give you outstanding results even when printing at ultra-high resolution using the latest 3D printers. Tested on a Wide Range of 3D Printers: We repeatedly and accurately test our filaments in-house, but more importantly, we act based on feedback from thousands of customers all across North America.
