Excellent thermal performance

Switched from an aluminum block to this copper one for better heat distribution on ABS prints. The difference in layer adhesion is noticeable. Installation was straightforward.

Solid replacement part

Needed a spare block for my second printer. This arrived quickly and matches the original specifications exactly. The grub screws included are a nice touch.

Great for beginners upgrading

I was intimidated by replacing my hotend parts, but this block made the process easy. Instructions online were clear, and this part fit without any modification. My prints look much smoother now.

Good quality, minor threading issue

The copper quality seems very high and it heats up quickly. I had to chase the threads slightly with a tap before installation, but once on, it works great. Good value for the price.

Works well for low-melt filaments

Using this primarily for PLA and PETG. It maintains temperature very steadily. Just be careful not to overtighten the screws as copper is softer than aluminum.

Perfect fit for my V6 upgrade

This copper block fits perfectly onto my E3D V6 setup. The thermal conductivity is excellent, and my PLA prints have never been more consistent. Highly recommended for anyone doing a hotend rebuild.
