Enhancing Sintratec Laser Parameters to Use 100% Old Powder

Показать описание

What started as a fun SLS Printing project for my kid, ended with a test run to fine tune the laser sintering hatch and perimeter values to ensure proper sintering of 100% "old" PA12 powder in the Sintratec Kit. Awesome stuff. We'll keep fiddling with the values to ensure we have proper fusion of the layers. If we can make a reliable workflow, this can really reduce the ratio of old and new powder in the future.

You can stop the curling by just increasing the IR lamp temperature a bit.

Hello, Thank you for the great video, what is your experience in slowing down the laser speed? I have been printing at 200mm/s because at the standard 500mm/s there were random parts of the model that the laser would not fuse well. I could see grey unsintered islands inside the model.
