Slice Engineering: Mosquito® Magnum Professional Hotend

The Mosquito® Magnum is adaptable to virtually any printer, so by swapping one component, you have the high performance benefits of a printer worth thousands more. Since the Mosquito® (designed for beauty) and Mosquito® Magnum (designed for speed) are the same length, any combination of these hotends can be mounted to one carriage. So you can switch between high-flow and high-precision in the same print.

Oh yeah, and you can change the nozzle with one hand.

Unlock engineering-grade plastics up to 500 °C. That means you can print car parts, medical devices, and whatever else you can dream up, and you don’t have to buy an expensive printer to do the job.

How did we accomplish this? 

We reimagined hotend design and structure from the ground up. Hand-selected materials execute specific tasks in each part of the Mosquito® Magnum to optimize your printer’s performance. 

Some might say it’s overkill. But we say it’s necessary to create something truly excellent.

We highly recommend the use of BN paste with the Mosquito® Magnum to provide good thermal conductivity between the hotend and heater/thermistor.

Unique Features:

• The Mosquito® Magnum prints upwards of 30 mm^3/sec
• A thermal insulator protects the extended melt zone from the effects of active cooling and radiative heat loss. It has a heat transmission rate as low as 3 W/m*K, meaning you can have ultimate confidence in the speed of your print, while at the same time maintaining the high resolution benefits achieved with the standard Mosquito® Hotend
• The melt zone is extended proximally upwards to maintain a small form factor
  Compatible with Rep Rap style nozzles which are characterized by their M6 x 1.0 threads, 7 mm threaded length, and 12.5 mm overall length
• A multi extrusion setup with both high flow and high resolution optimized designs can be created without needing to purchase new nozzles or make carriage modifications to accommodate hotends of different sizes
• Installation and assembly instructions available on our Documentation page
  

• Mosquito® Magnum Hotend*
• Mosquito® Magnum Mounting Hardware
• Set of Mosquito® Magnum hex keys for assembly, disassembly, and mounting
• Super tasty US-made gourmet lollipops
• *Fan, Heater Cartridge, & Thermistor sold separately
  

ADDITIONAL DETAILS:

Superior heat break performance
- The heat break conducts 85% less heat into the heat sink than a typical threaded heat break
- Steep temperature gradient at the heat break, and high tolerances along the filament path allow for better transmission of fine motor movements, resulting in beautiful, higher resolution prints
- Steep temperature gradient at the heat break reduces the likelihood of jamming
- Reduced heat transmission removes the need for a large heat sink
- Composite construction of the bimetallic heat break™ allows for the use of materials optimized for heat transfer in each section of the heat break
- Allows for hotend to be mounted with a printed, plastic adapter, without raising safety concerns

Increased structural rigidity
- The heat break has been separated from the structural components of the hotend, allowing for a heat break that is not load bearing, and can be very thin walled. This allows for a reliable, rigid exterior structure
- No components are prone to loosening at the mounting points
- Nozzles can be changed with one hand, without grasping the hot block
- In the case of a severe crash, an entirely new hotend is not necessary, parts can be easily swapped out

Larger temperature operating range
- Specially-engineered high temperature copper alloy in the hot block will not soften at high temperatures in excess of 550C.
- Threads in the hot block will not deform at high temps, allowing removal of nozzles even after multiple high temp heat cycles
- Nickel plating on the hot block reduces radiative heat loss and prevents galling of threads

Modular/adaptable to almost any FFF/FDM printer
- Compact, flat, ambidextrous form factor
- 5 different hole mounting patterns to allow for adaptation to virtually any printer
- Printable adapters can be created to diversify mounting options

Ideal for multiple extrusion systems
- Small form factor and light mass allows for back-to-back mounting with small nozzle-nozzle distance

Lightweight
- Small mass allows for more rapid motion
- Less reinforcement needed for the motors, belts, and drives in the motion system
