I am looking for the best filament to create parts that will hold a smart door …

For outdoor parts that will hold a smart doorbell device, you want a filament that is UV-resistant, weatherable, and durable against sun and moisture exposure. Here are some of the best filament options in the catalog for such requirements:

1. 3DXTech 3DXMAX® ASA Filament (Dark Grey) - ASA is well-known for its UV stability, durability in outdoor conditions, and mechanical strength, making it suitable for outdoor parts exposed to sun and weather. It also has a low-gloss matte finish which is great for technical-looking parts.

2. Canadian-made ASA Filament (Grey, White, or Black variants) - This locally manufactured ASA filament is designed for outdoor durability with UV and weather resistance, high mechanical strength, and good resistance to heat and impact. It's user-friendly and recommended for outdoor housings and enclosures.

3. Spectrum Smart ABS Filament (Yellow or Black) - Smart ABS has high impact resistance and rigidity, reduced shrinkage, and improved processing parameters that help with outdoor use. It can retain properties down to -40°C and withstands impacts well.

4. PETG-GF Filament (Black or Grey) - This glass fiber reinforced PETG filament offers increased rigidity, strength, and dimensional stability for structural and load-bearing outdoor parts. It is easier to print than some engineering filaments and has low warping.

Among these options, ASA filaments (3DXTech 3DXMAX® ASA or Canadian-made ASA) are particularly outstanding due to their UV stability, weather resistance, and mechanical properties ideal for outdoor electronics housings like for a smart doorbell.

Would you like me to add any of these filaments to your cart or provide more details on any?
