🛠️ HDry Lite Filament Dryer Update – New Features, Fresh Ideas, and Keeping It Cool! 🛠️

Hey team! Here’s the latest scoop on the HDry prototype. I’ve been busy adding features to make it super user-friendly and efficient in handling moisture. Let’s break it down!

1. Installed the Polimaker Dryer – Two installation options because, hey, everyone loves choices! 🎛️

  • Option A: This is the quick install on the back panel of the HDry Lite Filament Dryer. Just open it up, turn on the dryer, and you’re good to go! Ideal for anyone who loves a simple setup without much fuss.

  • Option B (DIY Mode): For the hands-on folks! I pulled the control panel off, extended the wiring, and now the HDry Lite Filament Dryer has its buttons and screen right on the front. No more flipping it around to adjust settings—just pure, DIY convenience! 🔧


2. New Inspection Windows on the HDry Lite Filament Dryer – Now with Side Views! 👀

  • The inspection windows on the HDry Lite Filament Dryer got a whole upgrade! I added side windows, so you can now peek in from multiple angles without opening it and messing with the carefully maintained conditions. It’s a small tweak, but it makes monitoring your filament a breeze.


3. Front Humidity Sensor – Data at a glance 📊

  • Added a sensor right up front to keep tabs on humidity levels in real time. It’s all about making sure moisture doesn’t sneak up on you, with instant feedback that keeps you in the know.


4. Breathable Membranes – HDry Lite can “breathe” now! 🌬️

  • To keep the HDry Lite Filament Dryer breathing, I added two special membranes. These high-tech additions (similar to what’s used in car and motorcycle headlights) let vapor out while blocking any dust or moisture from coming back in. So now, HDry can “breathe” naturally, but the interior stays nice and sealed off!


So, why the big moisture focus? 💡

Well , here’s the deal: if we build HDry Lite Filament Dryer as a sealed box with no moisture absorption isn’t really solving anything. It just makes water in the air – and whatever’s inside – evaporate but doesn’t get rid of it. Silica gel was an option, but when it heats up, it releases all that trapped moisture right back.

The ultimate fix? A little airflow! With this setup, as the air heats up, it expands and pushes excess moisture out through the membranes. The membranes are one-way, so they only let moisture exit – no dust or new moisture coming back in. It’s simple, practical, and does the job right without getting all fancy!


🔍 What Do You Think?I’m still testing and trying things, but I’d love to hear your thoughts! How would you tackle these moisture issues? let me know!

Thanks again for following along and for all the support!

See if a Python AMS would fit in it?

Hey there, buddy! As you can see from the photos, the size of the HDry Lite is exactly the same as the printer, so unfortunately, Python can’t fit inside.

Python is an awesome project, but its size just doesn’t quite fit with the design ecosystem of Bambu products.

If you’d like to chat more about it, I’m always here for you!

Big hugs! 😁
