With the growth of FDM 3D printing, the demand for 3D printing filament increases significantly. Among other materials, PLA is the most used in 3D printing applications. Wood filament is one of PLA-based material filament that can print object that has a similar characteristic to natural wood. With its biodiversity, Indonesia provides a lot of wood-based species. One of them is manau rattan, species with high demand but the limited application and hard to process. In this research, the manufacturing of 3D printing filament from PLA and manau rattan is studied. Rattan in powder form with 100-125 ?m, 75-100 ?m, and 50-75 ?m size are blended with Polylactic Acid (PLA) with 0, 5, 10, and 15% weight percentage. Mixing was done in a simple extrusion machine with three-zone temperatures: 131±5, 142±5, and 131±5 °C, also screw and puller speeds were maintained at 23±5 rpm and 10±3 rpm. Blended PLA/rattan then was tested with a colorimeter and melt flow indexer. Filament was then tested with a colorimeter and examined with a USB microscope and optical microscope. After the filament’s printability was examined, its printed product morphology and the defect were examined using a USB microscope, then its tensile and biodegradability properties were tested. The result indicated that PLA/rattan 3D printing filament with 90/10 composition and powder size 50-75 ?m has the greatest printability and is able to pair with commercial wood filament.
