Today we are reviewing the all-new Rapido Hot-End that comes with a PT1000 already installed. Making it so much easier to get into the higher temperature ranges, without modifying the ceramic heaters. We have opted to order one of these Rapido and install it onto our RatRig V-Core 3 CoreXY Printer for testing!
We ordered this item: https://www.aliexpress.com/item/3256803768566515.html but you could probably find a better deal over at the TriangleLab website.
Overview of Rapido PT1000
We opted to get the UHF version so that we could have the extra parts if we needed them, the UHF version includes both the HF and the UHF inside the box. If you wish to use UHF, you simply add the extended melt zone and nozzle and let it rip.
Klipper Firmware
We updated our Klipper firmware with the information TriangleLab has listed on the product page; and it started right up. The quality that we are getting versus the TriangleLab V6 Volcano is amazing! It’s quite impressive how well this hot-end melts and flows even on the 0.4mm nozzle included in the package.

Installation and setup is super simple, just download the proper EVA hot-end parts and print them prior to disassembly. We downloaded the EVA 2.4.2 Rapido hot-end mount and printed them in ABS, it meshed up with our existing Orbiter mounts so we didn’t need to reprint.
We opted to use the included wiring with the Rapido PT1000 so we could keep our Hot-End modules all wired up and together should we need to swap them into another printer. So we unwired from our BTT Octopus 1.1 board, and installed our new wires. Routed them to the hot-end and clipped them together at the quick-connects. In all it only took us about 45 minutes to complete this installation, easy.
Overview
Our final thoughts on the Rapido PT1000 is that it was certainly worth the wait, I am glad we didn’t pickup the first versions and opted to wait for a higher temperature thermistor option. I knew the flow rates on this Rapido were quite impressive, and I was ready to give it a try. The lightweight and modular package makes it perfect fit for my high speed RatRig CoreXY printer. For the price range of only around 100$ US it’s quite affordable compared to some of the other high-flow and ultra-high-flow hot-ends on the market. Head over to the TriangeLab 3D Printing website and pick up your new hot-end today!
