3d print: happy easter egg

Today I just printed out a bunch of Easter eggs that I hope will be a nice surprise for colleagues (when you’re back in the office sometime). Until then, I’d like to show some, I think quite interesting and successful pictures of the eggs, showing how the layer structures are built up, how something looks like at 300 micrometer layer height in FDM and that, depending on heat and material, sometimes threads form in cavities, which can be ...

Small 3d-print: Headphone (Bluetooth) charging problem helper

I’ve been having problems with my Bluetooth headphones lately, because sometimes they just wouldn’t charge anymore.

Well done one can only say. Of course things get even better if you can download the 3d data for it and print it out on your home FDM printer. The 3d model is available on the website - thanks for that :). But when I downloaded it, I noticed ...

Jewellery from the DLP printer Elegoo Mars

I am still at the beginning with the DLP printer but I have already found some nice ways to use it... Here for example for some small necklaces as little birthday presents: As expected, the resolution is very, very high, especially considering the size of the printed parts. More of this will be available here in the near future.

The basic equipment for a resin printer like the Elegoo Mars

While FDM printing can pass practically next to the desk, with UV resin-based printing you have to take safety precautions and also carry out a washing and curing process after printing. On the following picture you can see the different tools and aids I use for this: From left to right: kitchen roll: For cleaning metal parts breathing mask: Since we work with different chemicals (isopropanol and the synthetic resin), you should ...
