These blocks are engineered for ultimate high temperature performance. Made from a special high temperature copper-alloy with a softening point of well above 500C (compared to aluminium blocks which begin to lose integrity beyond 350°C), and much-increased thermal conductivity these copper blocks are perfect for high temperature applications while working perfectly with everyday filaments like PLA, ABS and spoolWorks EDGE.
In addition to high temperature performance these blocks have an advanced nickel based plating, this plating considerably reduces the adhesion of plastic to the block. This is great for everyday filaments keeping things clean and shiny, but is particularly important at temperatures above 300°C where a silicone sock can't be used.
Use these blocks with our plated copper nozzles for the ultimate extrusion pairing!
Copper has more than 3x the thermal conductivity of brass, and the copper alloy we use has been hardened and treated to reduce the oxidation that occurs in copper at high temperatures. A small side effect is that the copper's higher thermal conductivity will also slightly increase your heat-up times, but it can provide tighter temperature control as well.
This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C. It's perfect for the high-temperature printing that aluminium heater blocks can't handle.

Replacement nozzles for E3D hot end available in 0.25-0.8mm orifice for 1.75mm filament. Note that we have moved the 3mm options here
This is more than just a replacement, it is a serious upgrade that is also backwards compatible. This means that it works on E3D hotends older than the V6. It also works well on some other hot ends. We’ve tested it on the Reprapdiscount Hexagon, MP Mini, CR-10, and several others with good results.
Note that the standard hot end is brass. This is the best choice for most materials. However, for abrasive materials such as carbon fiber, glow in the dark, and stainless and iron filled materials, the stainless nozzle will provide a longer life. However, while the stainless is a longer life, it is lower thermal conductivity than brass so higher temps and/or slower speeds may be required.
The large bore has been elongated to give a minimum small diameter nozzle length. This reduces the potential for clogs.

Sanjay did a perfect job of explaining it, so we’ll just repeat his words!
From the E3D Blog:
Nozzle Specificity and Indentifiability.
While we were in the process of going over the nozzle we thought we’d address making them easily identifiable on a per-size basis. It’s fairly obvious whether a nozzle is 1.75mm or 3mm, but telling the difference between a 0.35mm and a 0.40mm is incredibly hard, and that’s before they get covered in plastic. To that end we have added spots drilled onto the hex flats of the nozzles, the number of which corresponds to a specific size of nozzle. The more dots the bigger the nozzle. We did consider using a binary code, but decided that we didn’t need 64 different sizes of nozzles in the end – maybe one day.
When a nozzle is printing it is not only outputting a stream of plastic, but also flattening it into its final stadium cross sectional shape. The width of this printed track is wider than that of the nozzles small diameter hole, as such the nozzle tip needs to have a flat on it that is at least as wide as the widest sensible track width. Because the widest sensible track width varies depending on the nozzle diameter it logically follows that the tip flat diameter should vary with the nozzle diameter.
Phwwoooar look at that proportional orifice-tip-flat relationship!
This means that with our larger 0.60mm and 0.80mm nozzles you can lay down fatter wider layers than ever before. This is great for large fast printing of super-strong objects, Nylons in particular benefit from being printed from big nozzles. Additionally you can create beautiful very glassy looking objects with big layers of PET type materials like _XT , T-Glase and Polycarbonate. **edit: A large diameter nozzle is also absolutely awesome for printing filled materials like woodfill and carbon fiber PLA.
For our smaller nozzle this means you can get even greater resolution and print smaller details and features in your objects. The smaller tip flat allows you to put down those small features and details without an over sized tip flat smudging the tracks adjacent to what is being printed.
These nozzles are also backward compatible with v5 and v4 so you can use them on existing hotends if you want to get some proportional orifice-tip-flat relationship goodness in your life without swapping out the whole hotend.

NOTE: This is the 5/17 revision of the silicone sock design. It has been modified to allow a bit more of the nozzle to be exposed. This will give a longer life at the expense of a slightly poorer thermal insulation. It is the right design for 90% of users, but if you know you need the higher insulation of the original sock, it is available here.
This product is compatible with the E3D cartridge style heater block on the V6. If you have an older bead style heater block, we have an upgrade kit available here.
For those who have printed with copolyesters like colorFabb XT, you know that if you don't nail the settings absolutely dead on, the nozzle can pick up little bits of material throughout the print. The bits collect until they are big enough to be dropped off in a gooey char blob. Doesn't usually matter much for function, but for looks it's not great.
The silicone socks help to address that issue with a non-stick surface that covers most of the nozzle and heater block leaving only the end of the nozzle sticking out.
The sock also provides the additional benefit of insulating your heat source. This allows for more cooling of your print for better bridges and overhangs without the concern of accidentally cooling your nozzle and causing temperature fluctuations (or the dreaded temp fall error). It also insulates your part from the heat generated from the heater block which will cause some improvement in quality.
It is expected that this sock may become worn or damaged over time, and they're cheap enough that the shipping is more than the cost of one piece, so we've bundled them into multi packs. Your future self will thank us.

If you want to build the Prusa Lack enclosure from their article and need the acrylic pieces then we have you covered. https://www.prusaprinters.org/cheap-simple-3d-printer-enclosure/
Acrylic can be very expensive at your local box store and the quality can vary greatly. So we have used our buying power to get you all of the acrylic pieces needed to make your own IKEA Lack enclosure. Our acrylic is manufactured to very high tolerances and is made from cast instead of extruded acrylic. Cast acrylic is stronger than extruded and has better optical clarity so you would get a wavy appearance looking at your printer go.
We have priced this lower than most box stores would charge and that includes free shipping in the United States.View full product details
PTFE, or Polytetrafluoroethylene, is a synthetic polymer commonly used as a coating for non-stick pots and pans. It is the slipperiest substance known to man, and is said to be the only surface to which a gecko cannot stick. Although Bowden tubes can be made from several different polymers, PTFE is generally considered the best because of its high melting point and low coefficient of friction.
1.75mm Bowden tubing, because of its small diameter, is made with an expensive paste extrusion process. Very precise equipment is needed to obtain a consistent shape and internal diameter. Additives such as colorant are difficult, because the PTFE doesn't readily want to mix with anything. Plain white PTFE is the cheapest and most common.
Capricorn tubing is manufactured using the most sophisticated equipment currently available. It always comes out perfectly round, and the diameter stays as consistent as possible.
Just like filaments, Bowden tubes vary in their real-world diameters. Tubing is often labeled as having an inside diameter of 2.0mm. The measured diameter may vary, however, anywhere from 1.75 to 2.15.
Capricorn XS Bowden Tubing is made from the highest quality pure virgin Japanese PTFE, and formed using the paste extrusion process. However, we have added a "Secret Sauce" which lowers the coefficient of friction. This additive also makes the tubing opaque.
XS tubing has a nominal internal diameter of 1.9mm, running from 1.85 to 1.95. This smaller diameter makes it ideal for printing flexible filaments, because there is no room for the filament to bind up inside the tube. The low friction coefficient allows any filament to glide through the tube with ease.
Important Note regarding interpretation of these specifications
Generally it is not safe to bring any PTFE above 260. The somewhat arbitrary melting temperature listed in this table is an indicator of stability of the material and is not indicative of a safe use temperature.

|♠Pulling Friction is calculated as the average force required to pull 1.2 meters of 1.75mm PLA filament through 1 meter of tubing at a constant speed, relative to 1 meter of cheap white reference tubing. Note that although we observed the friction of the TL series to be about the same or even slightly lower than our XS series, it also has a larger internal diameter.|
|♥PTFE does not transition quickly from a solid to liquid, but acts as a glass, slowly softening. Temperatures were approximated by heating samples of all tubing simultaneously, observing how quickly each one began to deform.|
