Instead of controlling extrusion speed with just distance/time, add an extrusion volume limit number as well and cap the extrusion speed to the slower speed of these two. In fact, the Simplif圓D default for my printer is 3600 mm/minute. So if I'm printing 0.2mm layers on my Wanhao i3 at a maximum of 2600 mm/minute with good results, I should be able to print at higher speed when using 0.1mm layers. The length of the trace per time is what you can control in Simplif圓D and Cura as the print speed, but it seems this completely ignores the layer height (except maybe in the warnings that you get from Cura). If the nozzle width is a constant and we assume that the path is always the width of the nozzle width, then the extrusion volume needed to fill the path depends on the length of the trace and the height of the slice. The ability of the hot end/extruder to melt and output enough filament to fill the required volume.įor this post, I'm just interested in the extrusion volume speed. Mechanical accuracy of the printer movements at high speed. I guess the relationship between print quality and speed comes from at least two factors:
In Cura, if I set the speed too high, it will warn me that I'm trying to push too much plastic through the nozzle, which seems pretty smart. All with a 3D printed air intake made on your machines!! Going to be taking over this industry as I am already working on a ZL1 camaro version.In Simplif圓D you control print speed as mm/minute and in Cura, it's mm/s, so there's a 1:60 difference there. I also have one that will be going out next week to a car that should break the 1/4 mile record. Which is great because my intake will be on the car. "My 3D printed intake just broke a world record for the fastest CTS-V half mile.Īlso in September we will be headed to Texas to break the mile record for the CTS-V as well. The CTS-V equiped with a 3D printed intake made by justin Taylor, a top engineer for modified custom car parts.
His blistering 192.2 mph（309.3km/h) marks the new world record for a stock blower CTS-V & CTS-V Sedan. Bruce Warren apparently wasn't happy with setting a world record once, so he beat his own record today in his Cadillac CTS-V.
