V6 Brass heater block


This is the mid-range V6 heater block. It is CNC machined from brass and suitable for higher temperatures. Standard aluminium heater block is not recommended for temperatures higher than 240°C, but this brass heater block can be used with much higher temperatures.

1. Is it a good choice for my 3D printer?

Standard 3D printers:
Suitable for all filaments.

High-end 3D printers:
I would choose a copper heater block plated with nickel.
It has better thermal conductivity, better thermal capacity.

2. What is inside the package?

You will get nice plastic case with a heater brake, silicone sock, screw for heater and a machine screw for thermistor.
So basically all you need 🙂

3. Material properties

For a better understanding how it works, I prepared some technical informations for you.

3. 1. Thermal conductivity

Thermal capacity is the amount of heat per unit time per unit area that can be conducted through a plate of unit thickness of a given material, the faces of the plate differing by one unit of temperature.

In short – how much energy does the material conducts.

Aluminium: 237 W/m*K
Brass: 109 W/m*K
Copper: 413 W/m*K

3. 2. Thermal capacity:

Thermal capacity says how much energy we need to warm up one kilogram of material to increase it’s temperature 1°C.

Aluminium: cca 890 J/kg*°C
Brass: cca 920 J/kg*°C
Copper: cca 385 J/kg*°C

3. 3. Thermal expansion:

Thermal expansion is increase in linear dimensions of a solid or in volume of a fluid because of rise in temperature.

We have a 3 dimensional object, so we need to use a volumetric coefficient of expansion which is about three times the linear coefficient of expansion.

Aluminium: 75 10-6*°C
Brass: 56 10-6*°C
Copper: 51 10-6*°C

3. 4. Density

Aluminium: 2710 kg/m3
Brass: 8730 kg/m3
Copper: 8960 kg/m3

4. Dimensions

All of these V6 heater blocks use design from E3D.

5. Weight

Brass heater block: 27.61 g
Brass heater block + silicone sock: 29.73 g
