New world document: Modded 3D printer completes ‘Velocity Benchy’ mannequin in simply 2 minutes!
Printing something on a 3D printer is an train in endurance. Although speeds have elevated an incredible deal over the previous two years, even one of the best 3D printers take hours to complete a medium-sized mission. Even small prints resembling Benchy, a ship mannequin that lovers use for testing, require 13 to half-hour on the quickest 3D printers we have examined.
Amazingly, Maker Monika McWuff was in a position to output a Benchy in simply two minutes and 9 seconds, because of her custom-modified Ender 3 Professional printer and its 120mm/s³ circulate price. She had posted an earlier video of the printer finishing the duty in 2 minutes and 19 seconds.
Solely the two:19 time has thus far made the #SpeedBoatRace LeaderBoard, a listing of prints that observe the official Velocity Benchy guidelines. Annex Engineering verifies the claims so maybe the two:09 time hasn’t been verified but. Both method, McWuff holds the brand new world document, besting a maker named Beraval who posted a time of two:40 in 2022.
We must always notice that Velocity Benchy prints do not essentially look nice and do not must with the intention to make the leaderboard. McWuff’s 2:09 print has a ton of stringing and mush.
Surprisingly, McWuff is new to 3D printing, having bought her first Ender 3 Professional lower than a 12 months in the past to make elements for an RC automotive. She obtained the inspiration to change an Ender after watching 247 Printing’s sub 3 minute Benchy and thought, “Pfff, how exhausting may it’s?”
She purchased a used Ender 3 Professional off eBay for $80 to begin the mission, then researched and taught herself how one can make the mandatory mods over the course of 5 months. McWuff admits she will be able to get form of obsessive about tasks, and “if you happen to can velocity run it, I’ll make it quick!”
A few of her mods are pretty customary, like KevinAkaSam’s Belt Pushed Ender 3, which changed the Z rods with, you guessed it, belts. This enables the printer to run clean, straight and exactly in sync.
Different mods are pure out-of-the-box pondering, like utilizing a flooring blower for cooling and bolting the printer to a 45-pound rubber bumper plate from the gymnasium. “I used wooden screws and a few brackets to screw the printer all the way down to the plate and dissipate vitality,” she stated.
There isn’t a number of the unique Ender 3 Professional left, just some aluminum extrusions and a part of the mattress, now coated in a sheet of carbon fiber. She makes use of her inventory Ender 3 Professional in a tented enclosure to print ABS elements for the mission.
The printer has 9 motors all collectively, with one for the extruder, 4 on the Y axis, two on the X axis, and two extra on the Z axis. She stated the motors are LDO, and she or he obtained an additional Ender 3 board from a buddy to run all of it. The machine additionally requires a second energy provide, which is simply laying randomly beneath the printer.
The hotend is very fascinating, and might push plastic sooner than foolish string. It’s a Trianglelab STD6 with a ceramic heating core, two extensions and a .4 CHT Volcano nozzle. A latest check clocked the circulate price at 120mm/s³. She’s hoping to get much more out of it by switching to a CHT V6 extender and a .5 Volcano nozzle.
McWuff is utilizing OrcaSlicer, and although Velocity Boat Guidelines have restrictions on layer top and line widths, there’s loads of wiggle room in different settings. She stated the gcode is modified by hand so she will be able to alter the temperature from 235 levels for the primary layer, 265 for the hull, then 215 for the cabin and 200 to complete. The print velocity tops out at 800 mm/s for infill and interior partitions, with an acceleration price of fifty,000mm/s². That’s 5 occasions sooner than a Bambu Lab A1.
A whole tour of the printer is on Monika’s YouTube channel right here.
We’ve clocked a number of quick Benchies at Tom’s {Hardware}, however since we’re testing inventory printers and customary slicers settings, none have pushed plastic sooner than the K1 Max with it’s 13 minute, 50 second Benchy.
For reference, a inventory Ender 3 Professional working at it’s regular 50mm/s and utilizing Velocity Boat settings can print a Benchy in a single hour and 4 minutes. With high-speed, Klipper firmware put in, the inventory machine can comfortably run at 150mm/s and print a Benchy in 42 minutes.
