 **Richard Hartmann:** No, you're right. One is additive manufacturing, and one is subtractive manufacturing, so it's literally coming from opposite ways... But the kind of thing at least I tend to do is roughly the same, which is basically useful stuff around the house, and you can use both for either. Or either for. You know what I mean.

 **Tom Wilkie:** Yeah, seriously. That was the whole RepRap thing. He printed the parts for me, and I beg, stole and borrow the components to put one together. It never really worked very well. I remember I bought one of Prusa's first products, which was a nozzle made out of peak. I've still got it somewhere. But that was so long ago. What's the story behind Prusa research? How long have they been around, and how did they come to be?
 
-**Pavel Strobl:** \[00:08:03.05\] Yeah. As you said, it started with Prusa Mendel. It's been 2012 by starting the company, but Prusa Mendel I think is 2009. And since then, Prusa developed multiple printers... i3 for yourself, Prusa Mini, Prusa XL, multi-tool, multi-material printers etc. But Prusa Research is not only about 3D printers, it's also about the software around, because even though you have amazing hardware, you have nothing without software. So amazing job that our developers did with the firmware, implemented the first input \[unintelligible 00:08:44.05\] without accelerometer. It's all calculated on the fly, but the values of the accelerometer are pre-calculated, and a lot of web services are online, like for example Prusa Hub or Knowledge Base, Prusa Shop, obviously... Printables, almost the biggest 3D model website that you you can find around. And there's a lot of stuff that isn't even seen, like Prusa support. That's probably the most interesting about us, because we have live support almost 24/7 for 3D printers. We have a Prusa forum, where you can ask; we have big community that we are grateful we have, and we are printing also the next 3D printers \[unintelligible 00:09:35.09\] because we can push forward because you are buying our printers, obviously.

 **Tom Wilkie:** Oh, my pleasure. Yeah. No, I remember when Richie and I were first kind of exchanging notes on 3D printing, and Richie was very keen to get in touch with someone at Prusa Research and see if they were using Grafana. Richie, I can't remember the exact story. Did we see it in a video? How did we, how did we first get in touch with Pavel?

 **Tom Wilkie:** One of the things that we designed Mimir -- I mean, I wrote the early versions of Mimir before it was called Mimir, when it was called Cortex. But one of the things we designed it to do is lots of parallel queries, and really be able to scale in that dimension. And we did it for fun, and it turns out, at the time at least, it might not have been the thing people actually needed, because most people needed what you've just described, which is querying over months or years of data. But the thing I'm most excited about is we've finally found a use case for being able to handle high concurrent query load. And it's this new Explore Metrics. So in Grafana, the Explore Metrics, when you click on a metric, it's gonna go off and do a query for every single label behind that metric, to see which labels have kind of outliers in, and what the distributions are. And so just clicking on a metric issues like 15 queries instantaneously, and puts a lot of load on the Mimir cluster. But it's something Mimir handles very well. And it's really interesting, because we've had a lot of users tell that story where "Oh, I'm moving off of Thanos, because I started using the explore metrics and it was killing my cluster. And so I'm starting to move to Mimir, or to Grafana Cloud." We run our Grafana Cloud Mimirs with many, many replicas of the querier, to deal with this exact use case. So it kind of was a solution in search for a problem for a while, but we've found one, finally.
