Abstract

The lattice-structure is used to enhance the strength of light-weighted material and 3D printing is a suitable method to produce light-weighted lattice-structure. This research focuses on the compressive strength of 3D printed polymer lattice-structure for lattice-structure without enhancement, fillet and ball enhancement with 1.4 mm and 1.6 mm diameter. The Acrylonitrile Butadiene Styrene (ABS) polymer is used as the 3D printed material in this research. Lattice-structures without enhancement and with enhancement have been designed by using Solidwork software. The 3D printed lattice structure specimens are then tested by using Instron universal test with ASTM D695 standard as reference. The result reveals that the specimen with ball enhancement has increased the young modulus for 1.6 mm diameter. The data and results from compression test which are then analysed by using hypothesis test show that the specimen fabricated with ball enhancement, 70 μm layer resolutions, solid print strength, honeycomb print pattern and 1.6 mm strut diameter has experienced different young modulus value as compared to that without enhancement.
