As Makers and suppliers of 3D Printers, parts and filaments here in South Africa, we have to admit that we’re addicted to printing in highly-abrasive materials. And despite the fact that nobody really enjoys the hassle of changing nozzles, we still believe that the amazing results you can get from Carbon Fiber, MetalFill and other Exotic Filaments far outweigh any negatives of the maintenance required to print the materials.

This is why we’re so excited to get these specialised 0.4mm Micro Swiss 1.75mm E3D Nozzles, as they are specially designed with extreme-strength A2 Tool Steel, which has been heat-treated to 57-62 RC and plated with an extra coating of “TwinClad XT” Nickel Composite to offer ultra-low friction, impressive wear-resistance, as well as a surprisingly good looking aesthetic. These 3D Printer Nozzles are made specifically to handle the extreme wear and corrosion of exotic polymers and materials like Glow-in-the-Dark, MetalFills and other 3D Filaments with highly abrasive characteristics.


Note: This is a Micro Swiss Original Nozzle, supplied directly by the industry leaders in nozzle R&D and Production. This ensures premium quality and lasting durability, even when dealing with high-corrosion filaments like Carbon Fiber and MetalFill.

Typical Applications for these 0.4mm Micro Swiss E3D A2 Tool Steel Nozzles:

Thanks to the impressive durability and wear resistance, some users have reported that, while a typical brass nozzle would wear down after somewhere between 100g to 200g of carbon fiber filament, these A2 Tool Steel nozzles can withstand up to 10kg before needing to be changed.

This is an incredible statistic that has driven so many Makers to upgrade from brass to more advanced materials, especially since these materials not only offer more consistent print quality over a long period, but can also save you the time and money that failed prints would typically cost. This is why they are the perfect choice when you plan on printing in abrasive filaments, as there are almost no other nozzles that can offer the genuine benefits of A2 Tool Steel, while still maintaining an affordable price.


Quick Guide to Changing your 0.4mm Micro Swiss E3D A2 Tool Steel Nozzle:

When swapping out 3D Printer Nozzles from other components, we recommend utilising the hot tightening technique for optimal thermal coupling. To do this, simply follow these easy steps, while being careful not to burn yourself of course.

  • Unscrew the heatbreak from the heatsink by about half a turn, to be sure you are not tightening against the heatbreak in later stages.
  • Heat up your hotend to 285°C, but do not overshoot as you risk damaging your thermistor.
  • Remove the existing nozzle from the heater block and insert the new nozzle.
  • While firmly gripping the heater block, slowly tighten the nozzle. Be careful, however, that you not apply any torque through the heatbreak, as they are fragile and relatively easy to break when loose.
  • Turn off the heating unit and allow the hot side to cool.
  • Finally, once the nozzle is installed and cooled down, tighten the heatbreak back into the heatsink and ensure that there are no loose parts.

The reason for this is that aluminium heater blocks have a different coefficient of thermal expansion than the materials used in the nozzles and heat breaks. This results in a small gap being created between the nozzle and the break inside the block when the hot end is at temperature, but this only happens if the nozzle has been tightened while cold.

Within 3D Printing, there are a few brands whose hard work has made them stand out from the rest, with real innovation and the ability to not only refine old designs, but actually redesign from the ground up to offer more comprehensive upgrades for 3D printing enthusiasts and Makers throughout the world.

Micro Swiss is one such brand that perfectly fits this description, and since their founding back in 2015, the Micro Swiss brand has garnered world-wide attention for the quality, material composition and precision of their hotends, nozzles and other all-metal components. With a core focus on TwinClad XT Plated Brass Nozzles and All-Metal Hotend Upgrades for some of the most popular 3D Printers on the market, it’s no surprise that one of the easiest and most effective upgrades available to Makers are Micro Swiss Replacement Parts and Upgrade Kits.

In addition to the amazing 3D Printing components and upgrades that they produce, Micro Swiss also specialise in Swiss Turning, which is capable of precision CNC machining outer diameters as small as 0.0127mm, as well as CNC milling, tapping and post machining finishing for prototyping. These service offerings and correlating skillsets ensure that the Micro Swiss team is more than just capable of producing consistently high-quality parts, but also capable of identifying precisely where each part could use improvements.

As manufacturers and end-users of everything they produce, Micro Swiss is one of the most impressive brands we’ve had the pleasure of dealing with, and we look forward to all of the exciting refinements and developments that they are bound to bring out in the future.
