3D-printing and UV-curing ...

... next week from 20.6. to 22.6. I'm on the FabCon in Erfurt and showing some of our systems - an XY-galvoscanner-lasermarker, a 3D-printing head on a CNC-machine ... and a pastedispenser/-jetter equipped with an UV-LED for curing UV-sensitive pastes. Here are some videos showing the first tests: h...

Re: Cleaning metal surfaces with marking laser ...

... not precise/fine enough to make own coins, but good for some laser-"engraving" and "drilling" ;)

Re: Cleaning metal surfaces with marking laser ...

... here some samples of "micro-machining" - did tests with varying hatch-densities and repeated engraving in brass and a multi-layer ceramic part. First the tests in brass - with 30microns hatch-spacing and 10x ablating it will "engrave" 0,3mm deep: Messing 1x 3x 10x.jpg Messing 1x 3x.jpg ... in ce...

Re: Cleaning metal surfaces with marking laser ...

... the last machine with the 20Watt-pulse-fiberlaser in the "white-blueish" housing is the prototype, I've developed for my company, which is planned to be selled in this size or slightly smaller, with some minor changes/updates. I'll present it on the next exhibition(s), and then it's again at hom...

Re: Cleaning metal surfaces with marking laser ...

... this is a common setup designed for a spot diameter of 30 microns, so not really special ;) In past I've got 30 microns too with a 60 Watt NdYAG and 20 microns with a diode-pumped 20 Watt-disk-laser. If I'll want a finer spot, this is possible with a beam-expander - have some with 2:1 or 4:1 rat...

Re: Camera delivers no images

... I have to "allow" camera use, when freshly plugged in and starting a camera software with Win7 and Win10 - could be, it's related to updated security settings?

Re: Cleaning metal surfaces with marking laser ...

... I've actually assembled the "serious" marking laser with a 20Watt (averaged) pulse-fiber-laser and did some testing on different materials. Here are some videos of the housing and engraving on metal: https://vimeo.com/214409447 https://vimeo.com/214745770 https://vimeo.com/215431737 ... and here...
