Product Of The Week - Goliath Hotend From VzBoT & Mellow 3D
In the ever-evolving world of 3D printing, the names VzBoT 3D and Mellow 3D stand out as catalysts for innovation. Headed by the ingenious Simon Vez, VzBoT 3D has carved a significant place in the 3D printing community. This post will take a quick look at these companies, their impact on 3D printing, and their exciting product, the Goliath Hotend.
VzBoT 3D & Simon Vez
VzBoT 3D, known for its high-quality and high-performance 3D printers and components, was born out of Simon Vez's passion and determination to enhance the 3D printing experience. Simon Vez is a respected figure in the 3D printing community, admired for his innovative designs and ability to turn ideas into functional, high-quality products. His commitment to enhancing 3D printing technology has had a considerable impact on the community, as his creations have set new standards in performance and reliability.
After witnessing his YouTube videos featuring his 3D printer performing at remarkable speeds, it's impossible not to get hooked. Simon is a true enthusiast, one of the few who persistently push the boundaries of pro-consumer-grade 3D printing. He pours his passion into his designs and products, generously sharing them with the community. His dedication and innovation have had a profound impact on the 3D printing community, making 3D printing more accessible and exciting for everyone.
Mellow 3D
Mellow 3D is a company that stands out for its commitment to innovation in 3D printer accessories. Their story began with their founder, May, a graduate in industrial design. After her first encounter with 3D printing in 2014, she was filled with curiosity for the industry and began to immerse herself in learning more about it. Recognizing the poor quality of existing 3D printing accessories, she teamed up with the NF team in 2016 to establish a company focusing on producing and selling 3D printer accessories, mainly extruders, hotends, and other products. Their collaboration with motherboard designer FLY in 2020 further strengthened their team.
Mellow 3D has since created many pioneering products for the industry, including extruders, hotends, and motherboards. Their design concept aims to bring more intelligent, interesting, high-quality, and practical products to customers, and better products with services to players and industries class printers.
VzBoT & Mellow 3D
The collaboration between Mellow and VzBoT has produced many great products with a focus on high quality and high-speed. Mellow has produced a lot of CNC-machined aluminum parts that would be typically made out of plastic on your average 3D printer.
Mellow really breaks the stereotype of Chinese manufacturers, where innovation and high quality are usually the last on the list of their priorities. They’ve shown a commitment to high performance that not many other companies have shown to produce.
Another one of their very popular products is the Vz-Hextrudort. VzBoT’s take on the Hextrudort by MirageC, this all metal extruder is light-weight, strong, and produces amazing speeds and print quality. It is slowly becoming the standard for users looking for high quality.
Goliath Hotend
Now, let's dive into the fantastic product of this collaboration: the Goliath Hotend. This incredible hotend, available in either air-cooled or water-cooled variants, offers a range of impressive features:
| Feature | Description |
|---|---|
| Aluminum Heatsink | Available in either water-cooled or air-cooled |
| Bi-Material Heatbreak | Chimera type Dzone made with Copper + Zirconia |
| Nickel-plated Copper Heat Block | Improves thermal conductivity |
| 100 watt 24v DC Nichrome Wire | Provides consistent heating |
| PT1000 M3 Brass Sensor | Accurate temperature sensing |
| Ability to print up to 550° | Supports a wide range of filament types |
| Long melt zone | 50mm to support high-speed printing |
| Designed for 9mm wrench tool to assist with nozzle changes | Facilitates easy maintenance |
| Uses V6-type nozzles | Compatible with a wide variety of nozzles |
Every detail on this hotend has had meticulous attention brought to it. The water-cooling feature stands out, allowing you to print any material in a completely sealed enclosure at high speeds without any clogging. This feature is a game-changer for 3D printing enthusiasts aiming for top-level performance. Simon has already pushed this hotend to 2000mm/s, showcasing the impressive performance capabilities of the Goliath Hotend.
Despite being an elite hotend, the Goliath is priced competitively. The air-cooled Goliath is priced at $171 CDN, while the water-cooled variant is available for $200 CDN. This price point makes it an incredibly attractive option for those seeking high-quality printing at an affordable price.
However, it's essential to consider the kind of printer you will be installing this hotend on. The Goliath Hotend is designed for printers that can fully explore its capabilities, not be limited by them. It's recommended for use with DIY CoreXY printers with their own respective communities, like Voron, HevORT, Rat Rig, or even an AWD VzBoT-Vz235 for the best performance.
The Goliath Hotend is a testament to how far 3D printing technology has come and the exciting advancements that lie ahead. Thanks to innovators like Simon Vez and companies like Mellow 3D, the future of 3D printing is indeed promising.
Where To Buy?
You can purchase the Goliath straight from Mellow3D on their official Aliexpress store.
Price
Air-cooled version - $171 CDN | Water-cooled version - $200 CDN
My Recommendation:
If you are planning on using the Goliath with the Vz-hextrudort, I recommend buying just the body of the Goliath (which is Set 3 on their Aliexpress listing) and pairing that with the water-cooled Hextrudort (either Set 3 or Set 4 on the Aliexpress listing).
This combo shortens the filament path to the absolute minimum and the water-cooling controls the temps on the hotend as well as the extruder.
For mounting, I recommend the CNC Aluminum Printhead Bracket. It’s an incredibly light and stiff option that allows a bunch of different configurations. Warning: this is only for the VzBoT 330 & 235 printers. There is a printed version which a lot of users have modded for their machines. If you are looking to fit a particular printer, you’ll have to do some searching through the various groups to see if someone has modified one that will suit your needs.

If you choose the water-cooled version, don’t forget your water-cooling setup, fittings, and tube.
