Says 411 grams. It looks like steel. Wouldn't you want aluminum? Wonder if it has any PTFE in it.by rsilvers - General
Does anyone know what the deal is with this? It looks like a good attempt. Not sure how well it would work, how heavy it would be, and how hot it can get (PC compatible?)by rsilvers - General
What do you mean by 5mm six times? If you said to extrude 30mm, it should extrude 5mm one time.by rsilvers - Slic3r
Put this into your start code: M92 E100 ; calibrate E Then tell it to extrude 30mm. Hopefully it will extrude 5mm.by rsilvers - Slic3r
I am thinking you are under-extruding. You need to: 1. Explicitly set the extrusion width in the advanced area of Slic3r. Set it to 1.4x layer height, but no less than the width of your nozzle - whichever is larger. 2. Then print a single-wall cube - say 30x30mm. Set infill to 0% an permitters to 1 and no top layer. 3. Measure the result. If it is not 30.00mm by 30.00mm, then adjust your X aby rsilvers - Slic3r
If you got 28.6, then change E600 to E629.37 in the start code area of Slic3r. BTW, I prefer to extrude 100mm as then my measurement error is less significant.by rsilvers - Slic3r
The subject of the contest was do take a Lego model of a car and do an interesting render with it. I made that image, and lost the contest (I didn't have enough family and friends to vote for it).by rsilvers - Developers
The child is a live photo. I had him hold his hands out. Then I over layed the render.by rsilvers - Developers
The robot does not look real. They are all obvious renders. Does this look real to you? I rendered it in Solidworks and entered a rendering contest with it six years and three months ago:by rsilvers - Developers

They designed it to hold four extruders side by side and back to back.by rsilvers - General

What this industry needs is a standard benchmark - say print a certain object at a certain scale and with certain infill. Everything spelled out. Then look at the run time.by rsilvers - General
"String trimmer line is not what you would call high quality plastic - very often the suppliers will throw in scraps, rejects, other plastic they have laying around because the chemical composition of string trimmer line simply doesn't matter in its normal use case, and they like to use up scraps when possible to save cost. So it's probably mostly nylon, but you have no idea of what else is in thby rsilvers - General
Water causes steam, and that can put bubbles into the print, making it cloudy and not as strong. While it worked fine, I did see some steam, and so I put the spool back in the oven and will try again tomorrow. I measured the line to get that value and did not go by what the label said. The extrusion multiplier is what I had just tested my PLA for, and used the same setting. At some point I wilby rsilvers - General
Myth. This test was able to detect 0.1 part per million. That is one part per 10 million or 1/100 of what OSHA allows an eight-hour exposure to.by rsilvers - General
I dried it in the oven for 24 hours at 180F. I still saw small puffs of steam, so I would dry it twice. The build plate is glass with a section of rip-stop BDU pants (65% Polyester, 35% cotton) spray-mounted to it.by rsilvers - General

I don't think 3D printers are overhyped. But having one at home now is like buying an Apple-II in 1979. It is no IBM mainframe. But it will change the world. We have another 30 years to go though.by rsilvers - General
