This is a filament dryer that utilize the heated bed from your own Bambu Lab A1 3D Printer. This 10h print contains 3 parts and ~420g of filament (~320g and faster if you use 1 wall).

Features:

-More efficient design, since the dryer cover the entire printer heated bed, the chamber heats up faster and less heat is wasted.

-A spacer to prevent your spool is not directly touching the bed, reduce the risk of overheating your filament.

-Holes for better air circulation, faster drying.

-Easy to print.

-Has enough space to dry 1 spool and many desiccant bags.

Instruction:

-Remove your build plate

-Place the Dryer Container on your heated bed

-Place the Spacer Inside the Container

-Place your Filament Spool and Desiccant Bags on top of the Spacer

-Close using the Lid

-Set your heated bed to a suitable temperature [*]

[*] Recommended drying settings for different type of filaments:

-PLA at 65-75c (I dry my Elegoo PLA at 75c without any problem, the chamber reaches an average 50c at this temp)

-PETG at 75-85c

-ABS/ASA at 90-100c (only if you print the dryer out of ABS/ASA, as PETG will melt at this temp)

-Dry at least 4 hours, flip your spools each 2-3 hour

Tips:

-Do not print it in PLA unless you only plan to dry PLA with heated bed no higher than 70c, print with PETG or ABS/ASA

-You can print with 1 wall only to save about 100g+ of filament, the dryer will perform the same, but some infill pattern will show up, this is aesthetic only

-Print with brim at corners to prevent warping (Recommended)

-For other 3D printers with heated bed smaller than 256mm, you can scale down the model to fit your printer

-I recommend using a Hygrometer/Thermometer to monitor your dryer chamber
