Solid Upgrade
Better than the stock aluminum block. Temperature stability is improved significantly on my V6 clone.

Good Quality
Fits well but threads were a bit tight on my heatbreak. Needed some careful tuning during installation.

Excellent Heat Transfer
Noticed faster heat up times compared to my old aluminum block. The PT100 fit is snug and accurate.

Perfect for PT100
Finally a copper block that fits the PT100 sensor properly without gaps. Highly recommend for high temp printing.
Q: What is the maximum safe operating temperature?
A: The block is rated for safe operation up to 300°C with appropriate thermal management.
Q: Does this support 24V heater cartridges?
A: Yes, this block supports standard 6mm heater cartridges compatible with both 12V and 24V systems.
Q: Do I need to use thermal paste during installation?
A: Using high-temperature thermal paste is recommended to ensure optimal heat transfer between components.
Q: Is the PT100 sensor included in the package?
A: No, this package includes only the copper heater block. Sensors and heaters are sold separately.
Q: Will this fit a clone E3D V6 hotend?
A: It is designed for standard V6 dimensions. Most clones are compatible, but tolerances may vary slightly.
