  Did you see strange parts video about this 3d printer? what is your experience? he had a lot of trouble and in the end said he does not think this printer should be sold as soon as the company wants (iirc)

  So awesome. Incorporating the pulse laser into the printing process for activation per layer is such a fantastic idea.

  A couple of points about the dichroic mirror to make your life easier:<br>-reflect the shorter wavelength and transmit the longer one (this should be already the default for your set-up) <br>-if possible (or economically viable), try to find a 1064 Nd:YAG laser for the activation: it will be hard to find a mirror able to split 447nm from 532nm(I guess that&apos;s your green laser) and sustain the two lasers power. Most of the dichroic mirrors on the market are designed for fluorescent microscopy. <br>-if possible, use polarised light: p for the one to be reflected, s for the one to be transmitted<br>-remember to add an antireflective coating on the back of the mirror, or you will start carving the side of your printer<br><br>Lastly, a plate mirror may introduce beam deviations and a tilt in the focal plane of the activation laser; on the other hand, a cube beamsplitter may interfere with the calibration of the printer laset.

  A company that just sells the product instead of requiring client interrogation first is indeed rare.

  Focusing a laser projector &quot;by ear&quot;!? That would certainly not have occurred to me, but it makes good sense once you explain it!

  Dude holy shit. I spent like 6 months trying to come up with an electroless copper recipe because I encountered the same issues of non-specificity on all the information and eventually gave up after smashing my head against the wall with so many failures. You are my hero for posting this. I cant wait to give it a go again. Thank you thank you thank you!

  3d printing metal inside structures could &nbsp;be interesting for making weird antennas

  Did not expect this channel to be a part of this Micronics embargo that flooded my feed today but couldn’t be more grateful

  It would definitely be cool to see a video specifically proving the idea of printing traces in areas that later aren&apos;t optically accessible.

  This could make some great RF metamaterials.

  I was working on 3D printed electronics in my phd. At the begining I had similar idea that you presented in <a href="https://www.youtube.com/watch?v=UIqhpxul_og&amp;t=980">16:20</a>, but my problem was achieving copper in the whole sintered layer. Finally I ended up with FDM and precision dispensing with laser curing of MOD ink, which composition I developed myself.
