...Muneeb Hassan; Aqeel A. Khurram; Numan Ghazali Purpose The purpose of this study is to develop a simple chemical method to remove support structure from hard-to-reach areas such as internal channels and cylindrical geometries of 3D printed Ti6Al4V alloy. Design/methodology/approach As compared...

...Chung-Tao Huang; Dian-Ru Li Purpose This study aims to reduce the material consumption, print time, and cost associated with the extensive use of support structures in fused filament fabrication ( FFF ), a common additive manufacturing ( AM ) process. To achieve this goal, it introduces...

...Ruiliang Feng; Jingchao Jiang; Zhichao Sun; Atul Thakur; Xiangzhi Wei Purpose The purpose of this paper is to report the design of a lightweight tree-shaped support structure for fused deposition modeling (FDM) three-dimensional (3D) printed models when the printing path is considered...

...Tsz-Ho Kwok Purpose Support structures are often needed in additive manufacturing (AM) to print overhangs. However, they are the extra materials that must be removed afterwards. When the supports have many contacts to the model or are even enclosed inside some concavities, removing them is very...

... by internal residual stresses, support structures are used in most selective laser melting (SLM) process especially for cantilever beams because they can assist the heat dissipation. Support structures can also help to hold the work piece in its place and reduce volume of the printing materials...

...Qiqiang Cao; Jiong Zhang; Shuai Chang; Jerry Ying Hsi Fuh; Hao Wang Purpose This study aims to further the understanding of support structures and the likely impacts on maraging steel MS1 parts fabricated by selective laser melting (SLM) at 45°, 60° and 75° building angles. Design/methodology...

... BESO code was able to reduce the support structure needed to build the simple two-dimensional cantilever beam by 15 per cent while keeping the mechanical performance at the same level. Originality/value The originality of this paper lies in introduction and application of the multi-solution nature...

... Stratasys Inc., the default FDM support structure for the base is composed of various layers with a sparse raster filling and a last layer (on which the model material will be deposited) with a refined raster filling (Figure 3). The first layers have a large positive gap – more than twice the filament width...
