FLSun has released their S1 Pro, a delta FDM printer that can print speeds of up to 1200 mm/s. I put it to the test, check out every one of the long list of features, and see if the S1 Pro is the printer you need in your shop.

Thank you FLSun for providing the printer for review, and thank you Sunlu for providing the filament used in this review.
