In 2022 and 2023, several FDM 3D printers were announced with extremely high quoted printing speeds. Traditional RepRap/Prusa-style FDM printers commonly had printing speeds of 50-100mm/sec, the speed they could reliably lay down filament onto the model. The following late-2022/early-2023 announcements began a race for speed. Since "Benchy the Tugboat" is commonly used as a speed benchmark, this is sometimes called the "speedboat race". There is in fact a website where people who build their own printers, or modify existing printers, can post speed ratings. The following are commercial, off-the-shelf FDM printers with their US retail pricing (for the assembled version and kit form where available) and the manufacturer’s rated maximum speed:
-
Prusa MK4 - $1099/$799 - web site doesn’t give speed rating
-
Bambu P1P - $699 - 500 mm/s printing, 20 m/s acceleration
-
Bambu X1C - $1199 - 500 mm/s printing
-
Creality X1 - $599 - 600mm/s
And in the do-it-yourself lineup:
-
"The 100", est US$350 to make, 400 mm/s printing, 100,000 mm/s2 acceleration.
-
Voron v2.4 - web site not easy to find information
All in all, there’s a lot of competition for the hearts and minds of FDM 3d printer users.
