Raise3D Pro3 Adapter for Bambulab Style Hotends

Description

I've designed an adapter to use BambuLabs-Style Hotends in an Raise3D Pro3. If you're asking “but why” would someone use cheap hotend or even clones in a so “expensive” Maschine like the Pro3. Simply said, it works (much) better than the original. Recomended print orientation is like on the picture, yes it requiers a lot of support. Also a illustrated assembly instruction will follow the next few days. Well short story long, here are some pro/cons on this: Pros: Flowrate: somewhere between Standard Pro3 and Hyperspeed Hotend, around 20-25mm³/s. (Depending on Filamenttype and which nozzle type/material) Cost: Mine was around 12$ with a hardened steel nozzle... (on Aliexpress) Cheaper Nozzles: you get cht style hardened steel nozzles for 2-3 bucks. Much faster heatup and cooldown times: Faster Heatup: Hyperspeed Hotend from 35° to 230°C -> 1:30min Standard Hotend from 35° to 230°C -> 1:14min Bambu Clone Hotend from 35° to 230°C -> 0:35min Faster cooling: Hyperspeed Hotend from 230° to 180°C -> 1:00min Standard Hotend from 230° to 180°C -> 0:59min Bambu Clone Hotend from 230° to 180°C -> 0:25min Faster reheat after Hotend switching: Hyperspeed Hotend from 180° to 230°C -> 0:32min Standard Hotend from 180° to 230°C -> 0:30min Bambu Klon Hotend from 180° to 230°C -> 0:13min This means, you save around 15sek each time when switching the nozzles, which adds up on the whole print! The faster cooldown helps with less oozing. We are there talking about 30sec. more of oozing with the original hotends after hotend switching! And you dont have to wait this long to change filament roll with this faster heatup time… Cons: -Actually it is a simply printed part, works well printed with the Hyperspeed ABS, but don't know if for longtime use it should be made of another material... I will recommend a good ASA with a High HDT A/B of around 90-100°C like Polymaker ASA. -You need to dismantle an original Thermistor Probe (around 12 Bucks, depending where you live) -You have to drill the Bambulab hotend (clone) to get the thermistor into place. -You also need the "expensive" JST PAP-02V-S which I have not found as single part only in packages from 10pieces upwards. The other original used parts are not modified and can be put back into the original form. For whom could it be of intrest? Standard Pro3 User: Well, you want to print a little bit faster with 0.6 or greater nozzle? you get around 1.5 to 2 times more flow... Hyperspeed Pro3 User: you can use the "old" Standard Hotends with your Hyperspeed Profiles only use 75% to 80% Speed. For both: -you print parts with dual hotends where layertimes are short and so switching times are crucial for time saving. -you print parts with highly abrasive filaments and therefore have to buy new nozzle all the times... so you can save a lot of money... KEEP IN MIND!!! You can or surley will loose waranty and if you got problems with this hotend/prints the Hotline/Service would surley not help you when not using the original hotend. I am not responsible for any damage that can occur when using this part! PS. would be nice if you give a little tip when you're satisfied with the results Here are some impressions: https://youtu.be/0a2Be6OtkTU?si=PciRMao_9_4FuU9V https://youtu.be/WD_FjvKrcCk?si=0yTPu7BaHQxC1DLq
