🔍 Dive into the world of 3D printing with ASA filament! In this post, we'll explore the challenges encountered and the innovative solutions devised as we embarked on our journey of crafting coffee portafilter holders using ASA filament at the 3DEXPERIENCE Lab Munich – FabLab.
WHY ASA ?
ASA filament stands out for its exceptional durability, mechanical stress, and thermal fluctuations. With coffee portafilter holders exposed to high temperatures during brewing, ASA's resilience becomes indispensable.
CHALLANGES & ADJUSTMENTS
Encountering Initial Welding Issues: Our first attempt uncovered welding challenges during printing, prompting us to reevaluate our approach.
Glue Stick
Adjustments were made to address these challenges:
Speed Fine-Tuning: The initial layer speed was reduced 50 mm/s to 25 mm/s to enhance print stability.
Boosting Adhesion: An outer 15mm brim was added to enhance adhesion and prevent warping. Also, the brim object gap was adjusted to 0 for prevent warping.
Temperature Control: Temperature optimization was crucial; thus, nozzle heat was adjusted to 250°C and engineering plate temperature to 110°C for optimal printing conditions for ASA.
Using Glue Stick: In our effort to improve adhesion and prevent warping, we decided to try using a glue stick. This simple addition was really helpful in making the prints stick better and keeping them from warping, making our printing process much smoother.
