The F306 can print at a maximum speed of 250mm/sec. What’s the impact on part quality when the F306 prints at 250mm/sec. Fusion3’s patent-pending motion controls system is designed for high-speed printing. For many parts there isn’t a noticeable quality change printing at higher speeds. When printing parts with many corners and small features at 200 or 250mm/s, you may see some “artifacting” in corners where the printer is slowing and then accelerating around the corner.
