Even the best 3D printers take a lot longer than this

Printing anything on a 3D printer is an exercise in patience. Though speeds have increased a great deal over the past two years, even the best 3D printers take hours to finish a medium-sized project. Even small prints such as Benchy, a boat model that enthusiasts use for testing, require 13 to 30 minutes on the fastest 3D printers we’ve tested. Amazingly, Maker Monika McWuff was able to output a Benchy in just two minutes and 9 seconds, thanks to her custom-modified Ender 3 Pro printer and its 120mm/s³ flow rate. She had posted an earlier video of the printer completing the task in 2 minutes and 19 seconds. Only the 2:19 time has so far made the #SpeedBoatRace LeaderBoard, a list of prints that follow the official Speed Benchy rules. Annex Engineering verifies the claims so perhaps the 2:09 time hasn’t been verified yet. Either way, McWuff holds the new world record, besting a maker named Beraval who posted a time of 2:40 in 2022. We should note that Speed Benchy prints don’t necessarily look great and don’t have to in order to make the leaderboard. McWuff’s 2:09 print has a ton of stringing and mush. Surprisingly, McWuff is new to 3D printing, having purchased her first Ender 3 Pro less than a year ago to make parts for an RC car. She got the inspiration to modify an Ender after watching 247 Printing’s sub 3 minute Benchy and thought, “Pfff, how hard could it be?” She bought a used Ender 3 Pro off eBay for $80 to start the project, then researched and taught herself how to make the necessary mods over the course of five months. McWuff admits she can get kind of obsessive about projects, and “if you can speed run it, I will make it fast!” Some of her mods are fairly standard, like KevinAkaSam’s Belt Driven Ender 3, which replaced the Z rods with, you guessed it, belts. This allows the printer to run smooth, straight and precisely in sync. Other mods are pure out-of-the-box thinking, like using a floor blower for cooling and bolting the printer to a 45-pound rubber bumper plate from the gym. “I used wood screws and some brackets to screw the printer down to the plate and dissipate energy,” she said. There isn’t a lot of the original Ender 3 Pro left, just a few aluminum extrusions and part of the bed, now covered in a sheet of carbon fiber. She uses her stock Ender 3 Pro in a tente
