At H and H 3D plastics we understand the challenges and frustrations associated with receiving poor quality filament. Our filament is proudly Made in the U.S.A. with the strictest of quality standards. We pride ourselves in providing a quality product to our customers allowing you to print with ease. We use only the best virgin polymer for our filament. Our plastic is thoroughly dried prior to extrusion and each roll is vacuum sealed with a desiccant within minutes of being wound. This ensures that you receive the driest filament possible. Our diameter is checked in line with a laser diameter gauge to guarantee that each roll you receive falls within our +/- .05 mm diameter standard. We wind our filament with precise torque control and stepper motor accuracy to ensure layer by layer our filament will not tangle during printing. We print daily with our filament to ensure that the filament you receive is of the highest quality. We manufacture our own filament we are not just a distributor, this is gives us more control over the quality of our product and allows us to provide you with the highest quality filament possible.
