The Rapido UHF is $100 and the Bambu hotend is $35. I only get a little more flow from the UHF and if it breaks, clogs or fails in anyway, its not worth it to me.
I can get Rapido for around $70 if I have the patience to wait for the right deal and probably around $25 for the bambu. There's an huge difference.
Regarding breakability I really can't comment, you're the only one I've heard with such experience. You didn't provided the details I asked for in the other thread, so looks like when such stuff breaks is very difficult to determine the cause. Will try to investigate, but without further details I should consider this as in isolate case and, as such, a one time only purchase which needs to be repeated at the end of the life cycle it has been designed for.
I'm very surprised you only get a little more flow
:
Feature | Rapido UHF | Bambu Lab X1C Hotend |
---|
Type | Open-source, ultra high flow | Proprietary, compact all-in-one |
Max Flow Rate | ~65 mm³/s (up to 75 mm³/s) | ~20–30 mm³/s |
Nozzle Swapping | Requires wrench (Revo-style or standard) | Tool-free (quick swap nozzle units) |
Filament Compatibility | Full range: PLA, ABS, ASA, PC, CF, etc. | Most standard filaments, incl. some composites |
Max Temperature | 350–500°C (UHF supports high-temp plastics) | ~300°C (firmware-limited) |
Heater Power | 60–90 W cartridge heater | Integrated low-wattage ceramic heater |
Sensor Support | PT1000, thermistor (configurable) | Built-in thermistor |
Compatibility | Mounts on Voron, RatRig, etc. | Only works with Bambu printers (X1C, P1P, etc.) |
Build Format | All-metal, single-piece melt zone | Swappable core with short melt zone |
Cooling Design | High-performance, active fan cooling | Compact blower fan design |
The Rapido wins basically in everything and Bambu Lab can't even compete in flow rate. I'm left with two only possible explanations:
- Rapido manufacturers advertises fake specs
- There is some flaw in your setup
If what you say is really what to expect from a "Voron with RUHF vs Voron with X1C hotend", then I'm not sure it worth. Remains only the higher temperature and related filament compatibility. A great bonus for sure, but alone is not enough to justify so much extra money.
I must admit you left me with big doubts about Rapido.
The Voron cost more then the Bambu labs X1C with AMS.
I didn't checked the parts needed. This is a kind of mod that can only be evaluated from an existing user which knows every details of the printer along with the costs he faced to complete the build. For sure, it will be a big NO if is going to be more expensive than the X1C.
But they are just differant printers. One is more fun to build and mod and one just works out of box without much intervention.
This is where I've heard the most conflicting opinions at the time I've investigate on the matter. Many users stated that Bambulabs work out of the box without much intervention with the Voron continuosly requiring intervention. However, many other Voron users stated they didn't faced anything of this and highlighted the fact that mainly depends from how the printer has been optimized and built.
I think we're in a field where there's not a clear winner, it is strictly tied to the attitude the user takes when he is going to build.
