Polymaker PolySonic PLA, 1.75MM, 1KG - Grey Your Projects, FASTER! PolySonic™ PLA is a revolutionary high-speed 3D printing filament, the ultimate game-changer in additive manufacturing. With its lightning-fast extrusion rate, cutting-edge precision, and exceptional layer adhesion you can ramp up the speed of your 3D printer and witness new levels of productivity. Accelerate your workflow without compromising on strength or quality. What is a High Speed filament? A material is considered "High Speed" if it fulfills the following 3 criteria at a set printing temperature: Flowability: It can extrude consistently at 24mm3/s on popular extrusion system. (equivalent to 300mm/s at 0.2mm layer height with a 0.4mm nozzle) Formability: At 24mm3/s, it maintains similar surface quality, overhang and bridging as printed at lower speed. Functionality: At 24mm3/s, it maintains at least 80% of its overall mechanical properties when printing at lower speed. (mainly: layer adhesion, tensile strength and impact strength) PolySonic™ PLA at 230˚C Maximum flow*: 29mm3/s** (tested on a customized extrusion platform equipped with an E3D volcano hotend, 0.4mm nozzle with Hemera XS extruder) Confirmed similar quality Polymaker Scientist when printed at 4mm3/s and 24mm3/s Layer Adhesion at 4mm3/s-24mm3/s: 37.3-32.3 MPa (Maintain 87%)Tensile Strength at 4mm3/s-24mm3/s: 46.0-43.9 (Maintain 95%)Impact strength at 4mm3/s-24mm3/s: 6.1-5 kJ/m2 (Maintain 82%)* Maximum Flow: Flow at which the measured flow is decreasing below 95% of the requested flow.** For 0.2mm layer height with 0.4mm nozzle: 29mm3/s -> 363mm/sFor 0.1mm layer height with 0.4mm nozzle: 29mm3/s -> 725mm/s What are the advantages of using a High Speed filament? Surface Quality at high speed:When printing at high speed, the nozzle will actually experience a wide variety of speed going from 0mm/s to the max speed set on the slicer. The higher the max speed, the wider the range of different speeds. The issue is with the printing temperature being the same, the extrusion temperature will vary dramatically leaving difference surface finishes on the print (from glossy to matte because of a phenomenon called: Shark Skin), High Speed filament reduces these differences by displaying similar surface finish in a wide range of flow rates.Additionally, high speed filament will extrude much more consistently within the speed range providing a smooth surface whereas regular filament will display holes, artifacts and layers with different thicknesses. Mechanical Properties at high speed: High Speed filament will display far greater overall mechanical properties when printed at higher speed than regular filament because of the more consistent extrusion and the optimized cooling/melting rate of the polymer. Higher Throughput:Thanks to 1) and 2), you are able to output the same quality part at a much higher pace from your 3D printer. This advantage is ideal for businesses using 3D printing to produce their products. Printing and Drying Settings?
