    <a href="https://www.youtube.com/watch?v=ISC7ktG1EhI&amp;t=390">6:30</a> Let me guess, it&apos;s because they make filament for a bunch of other brands and they don&apos;t want you to show who.

    Wow, that sound canceling you did was pretty impressive. &nbsp;I get why you had to cut the packaging segment, SUNLU probably makes packaging for other manufacturers and if we knew, we could get SUNLU filament cheaper potentially since it&apos;s the same.

    I switched from PLA to PETG and have practically settled on Sunlu. Excellent price/performance ratio. No surprises. Allways good quality.

    I get most of my filament for personal usage from sunlu. Highly appreciated the tour

    This is a really great video! Sorry I&apos;m so late to seeing it. Love using Sunlu&apos;s filament products and it&apos;s great to have a view on how they are being made.

    Just ordered a batch of filament from them. Should be coming in in the next couple of days.<br><br>P.S. maybe i&apos;m the only one, but the 360 camera shots was making me a little car sick sometimes.

    Just some quick math:<br>6 floors with 25 machines each means 150 total machines, over a month they produce ~1.8 million killograms of filament.<br>That works out to about 400 spools per machine per day.<br>The fastest industrial machines I could find produce 130m/minute of filament and a 1kg spool of PLA is ~335m long.<br>That&apos;s approximately one spool per 2.5 minutes or 24 spools an hour.<br>That would mean that there are workers at the machines for at least 16.66 hours every single day year round and all that is assuming max run speeds, no failures and some generous rounding.<br>No wonder they need to live right next to the factory...

    I&apos;m going to go ahead and say Sunlu is probably one of the best brands for filament. Sad that it&apos;s hard to get here, but when it appears on sale, I try to get it.<br>Recently got their Meta PLA, its amazing for miniatures. The other one I love is the matte black PETG.

    I have ordered SUNLU through Amazon twice and got quick turn-around both times. Makes sense now.

  • @t3chninja_official · 8 months ago

    I love Sunlu filament. It was my very first filament I purchased and I have had zero issues with their filament. I believe they also manufacture Jayo filament. I have gotten a few of those rolls and the boxes plus the spool were the same ones as the Sunlu ones. Again I&apos;ve never had any issues with any of their filaments. It&apos;s my go to brand when I need to purchase more.
