Increase your extrusion multiplier until you're happy. The Infill Extrusion Width value can be increased to 200% or even 300% to make it so that more material is extruded for the sparse infills. Extruder Calibration is an easy process for you 3D Printer. Thank you for the suggestions. Create Upload a Thing! How Is Extrusion Width Calculated? Well, it does if it’s properly calibrated. I reduced the width to .2mm and i got a solid mostly airtight layer. Here is an example: Your original extrusion multiplier = 1.00 and your average perimeter thickness = 0.441mm. On the other hand, if you’re having some over-extrusion in your prints, you should probably lower your printer’s flow rate. Do so in 5% increments, and check for print quality improvements. While printing my hundred or so calibration prints i ran across this effect you mention. We'll also cover how to dial in your extrusion multiplier in your Slicing Software. The "print really slow" test bars didn't do anything exciting enough to post them last week. If extrusion multiplier is below 0.95 or higher than 1.05, re-check step 1 above, as likely e steps per mm is off. They were visibly more over-extruded at 1.6 mm^3/sec nominal than the 6.4 mm^3/sec nominal samples, which isn't terribly surprising. Measure the walls with a caliper in several places (at least 8) and get an average. I had it set to 0.42mm to calibrate my extrusion multiplier and I've left it at that with a 0.35mm nozzle and and 0.1mm layer height. So I did not see the extrusion width variable in Cura's output gcode so the 0.44 mm first layer width was a calculated value by looking at the gcode finding two parallel lines and adjacent loop segments, comparing the coordinates, etc to make the calculation. Education Thingiverse Education Jumpstart. Extrusion Width: Auto or manual? Calculate your new extrusion multiplier using the formula on the second image. Too fat lower Extrusion multiplier too thin raise, reprint repeat until it is correct. The correct extrusion width should yield a segment 20mm X 20mm with no deformations. Measure all the perimeters of your cube and calculate the average. I'm playing around with various settings now I've got my SD3 dialled in and I'm curious if whether I should put the extrusion width back to Auto (Simplify3D)? If your single wall model is 2mm tall and you are printing at a layer height of .2, … Customize a Thing. Use this calibration tool to fine tune your printer.

So I print a single walled square and use an accurate digital micrometer to measure the wall thinness. Calculate your new extrusion multiplier using the formula on the second image.

If not, edit 'Calibration 0.4mm' and on Extruder tab, adjust extrusion multiplier up or down, save, and slice/print again until 0.4mm is measured. When i was printing with the fat .4-.8mm first layer in my journy, i notice the detachments were starting to occur from places not adjacent to an edge. I run a 0.4mm nozzle with 0.5mm extrusion.

Like with under-extrusion, flow rate adjustment is not the only fix for over-extrusion. Change your extrusion multiplier: new multiplier = old multiplier x (extrusion width / average measurement) Repeat until you are happy. How To Calibrate Your Extruder.
