TL;DR

This content explores the advancements and challenges of the 247Zero 3D printer in achieving high-speed, high-quality printing.

Transcript

This is my famous Voron Zero aka 247zero!  Speedbenchy world record and up to 1000   mm/s printing - yeah: It’s crazy  fast and it’s been a while. Now,   it’s time to revisited and to review that beast  of a 3D printer. Why did I choose those upgrades?   How fast is it really at quality printing? What  needs to be improved in order to go even faste... Read More

Key Insights

• 🖨️ The Voron Zero 3D printer, also known as 247zero, is known for its fast printing speeds and has received a lot of interest and downloads from the community.
• 🔩 The key philosophy behind the 247zero concept is to improve printer components, motion system, cooling, and extrusion capabilities in order to achieve faster and higher quality prints.
• ⚖️ Stronger stepper motors alone do not improve print quality at higher speeds due to increased forces that can cause displacements. Cutting weight from moving masses is crucial for accuracy and print quality.
• 🔧 Upgrading the motion system and using longer meltzones with high-flow hotends, like the Volcano style heater block, enables faster extrusion rates and higher speeds.
• ❄️ Cooling is a challenge for fast printing, and the Voron Zero has experimented with larger fans and externally-mounted part cooling inspired by MirageC’s HevACS for effective cooling.
• 🕓 Comparing print times, the 247zero is significantly faster than printers like the Prusa MK3S+ and the BIQU Hurakan. It represents the next generation of printers that will be more than two times faster than current models.
• 🔍 The print quality of the 247zero is comparable to other printers, but there are slight surface imperfections due to wonky frame and moving bed, as well as lack of torsional stiffness in printed components. Solutions for these issues will be discussed in the next video.
• 🔇 The cooling performance of the 247zero is sufficient, but auto-cooling is challenging to dial-in without warping. The energy consumption and noise level from the fans are high. Enclosure and a capable external power supply are not possible with the current design.
• 💡 The next video will address the fixes and improvements for the 247zero, including alternative hotends, nozzles, and extruders, as well as reducing weight on the moving masses. The goal is to close the gap between fast printing and high quality.

Questions & Answers

Q: How does reducing moved masses contribute to achieving higher quality prints at faster speeds?

By reducing moved masses, it allows for higher accelerations without compromising the stability of the printer's construction, resulting in better print quality. Stronger motors may increase acceleration but can lead to displacements and quality issues.

Q: What upgrades were made to improve the extrusion capabilities of the 247Zero printer?

The author experimented with longer meltzones and used a Volcano-style heater block for the Mosquito style heatsinks and heatbreaks. This allowed for faster melting of filament, enabling higher extrusion rates and faster printing speeds.

Q: What challenges were faced in optimizing the cooling system for the 247Zero printer?

The Voron Zero has a bowden toolhead, which posed challenges for part cooling. The author experimented with various fan configurations, including externally frame-mounted cooling inspired by MirageC's HevACS. While effective, cooling had to be carefully balanced to prevent warping and excessive energy consumption.

Q: How does the 247Zero compare to other popular 3D printers in terms of print speed and quality?

The author compares the 247Zero to the Prusa MK3S+, BIQU Hurakan, Bambu Lab X1 Carbon, LDO Voron 2.4, LDO Voron 0.1, and Flsun V400. The 247Zero is significantly faster than most printers while maintaining comparable print quality, positioning it as a next-generation printer capable of more than twice the speed of current models.
