3D Printing Filament in Singapore
Stores
- Amazon.sg
- CC3D Singapore (~S$16/kg, next day delivery)
- Taobao
Favorite Filaments
PETG
- eSUN
-
- + Great general-purpose filament
- + Good tensile strength
- + Good heat resistance
- ± Flexible
- + Stringing can be completely eliminated with retraction length calibration
-
- CC3D
-
- + Great general-purpose filament
- + Good tensile strength
- + Good heat resistance
- ± Flexible
- - Fine stringing that cannot be completely eliminated with any length of retraction
- Colored filament is not completely opaque, could be useful for single-layer LED shine-through
-
PETG Composites
- Tinmorry
-
- + Great general-purpose filament
- + Good tensile strength from PETG
- + Good yield strength/impact resistance from glass fiber
- + Great heat resistance
- + Matte surface texture
- - I had extreme reel to reel variance, one reel was ~1.79mm diameter while another was
~1.82mm diameter, measure and set extrusion multiplier per reel! - Use the link above to order rather than the usual product listing page, as the store blocked orders from non-mainland China access
-
PLA Composites
-
- + Prints are very strong without being too brittle
- + Matte surface texture
- + Soft light diffusion
Disliked Filaments
- eSUN
-
- Prints are very flexible and soft in XY axis, strength is only in the Z axis
- Probably has to do with the orientation of the carbon fibers due to extrusion
-
- ABS
- Filament shrinks during printing
- Prints will end up slightly under-sized, especially in X-Y axes
- Perimeters warp upward like mad throughout the print
- Print will detach from the bed and fail, which can be mitigated by a large (≥1 cm) brim
- Even with a brim, the first layer will still have warped perimeters
- Fills your home with noxious fumes during printing
- Plenty of modern alternatives to attain similar properties, e.g. composite blends (-GF, -CF) or polymer blends (PETG HT, PC blend)
- All PLA/ePLA
- PLA glass transition (softening) temperature is around 60°C, making it unsuitable for many warm environments like direct sunlight, vehicle interiors, electronics enclosures, etc.
- PLA is not dimensionally stable - creeps over time at any temperature
- PLA polymer biodegrades over time, becoming brittle or breaking down into various chemicals
