Low Density, High Strength, Excellent Chemical Resistance, FlexiblePolyethylene (PE)-based Olefin Block Copolymer (OBC) is made from a unique polyethylene-based material.3D-Fuel, in partnership with Dow Chemical Company, have produced the IMAGIN3D(tm) OBC filament - a breakthrough material that brings polyolefin properties to 3D printing without the issues commonly associated with printing polypropylene.OBC is a high-performance build material that enables the production of lightweight and durable 3D printed parts. It is best suited for 3D printers who need a high quality, lightweight chemical resistant filament. This new material offers some great characteristics including:Excellent PrintabilityLow Density (0.905 g per cm^3)Higher DurabilityExcellent z-axis property retentionChemical ResistanceConsistent Printingand Low OdorThese material benefits enable new, high-end applications. OBC’s low flexural modulus and extreme fatigue resistance make living hinges easier and longer-lasting than ever. The low-density, durability, and chemical resistance are excellent for UAV, automotive, marine, and R/C applications.For best results, use a PP- or PE-based build surface. Clear packing tape is an excellent, low-cost build surface option.NOTE: Because DOW OBC is such a low-density material, the spool weights are lower than you might expect, but a full spool of OBC (768g) will print the same amount of parts as a 1kg spool of PLA. Pretty crazy, right? It's an excellent material for doing weight-reduction on your 3D printing projects.For best printing results, use Layerlock PP for the build surface and Magigoo PP for the surface adhesive. Magigoo PP + glass build surface will also work well.Printing parameters:Print Speed: 10-40 mm per sExtruder Temp: 170-200° CHeated Bed: 60-100° C
