“…One of the mostly used 3D printing technology is Fused Filament Fabrication (FFF) which uses filaments or thermoplastic materials in thread form. The filament is inserted into a heated nozzle and extruded once it reaches its semi -liquid state [5]. PCABS is just one of the materials that can be printed through such method and is currently being explored due to its applicability in consumer products, high durable prototypes, mechanical parts, casing, and other end use parts.…”

3D printing is now being applied in various research areas due to its ability to produce highly complex parts whenever needed. This is highly helpful in the fields of robotics; radiation environment monitoring and space applications where stand-alone equipment are usually required. In this work, FDM 3D-printed polycarbonate acrylonitrile butadiene styrene (PCABS) samples were subjected to 1 kGy to 9 kGy of gamma irradiation from a Cobalt-60 irradiator. Parameters such as infill density and dose rate were modified to determine the best setting to improve the mechanical characteristics of the 3D-printed thermoplastic. Results show that samples with lower infill density obtain higher ultimate strength when exposed to higher doses of radiation.

Fused Deposition Modeling (FDM) is one of the most common polymer 3D printing technologies used in many applications today. However, limited volume capacity for 3D printing large parts or components is the usual downside of this technology, especially desktop 3D printers. Hence, to offset this limitation, the 3D-printed parts are often designed in multiple pieces and assembled after printing, which requires post-processing called cold welding. Such welds are also quite strong but not as strong as a single-piece print. Therefore, finding suitable parameters or settings that can provide substantial strength for cold-welded 3D-printed parts will be beneficial. This study aims to determine the failing behavior and shear strength of ABS FDM 3D-printed single-lap joint using ABS glue as adhesive. Specimens were printed with varying raster angles (+45o/-45o and 0o/90o) and layer thickness (290 μm, 190 μm, and 90 μm) to investigate the effects on the adhesion or shear strength and failure mode of the acetone welded 3D-printed joints. Results show that raster angle and layer thickness significantly affected the shear strength of acetone welded materials. Single-lap joint test sample printed with +45o/-45o raster angle reveals higher shear strength than specimens printed with 0o/90o raster angle. Results also indicated that the gaps between the raster and voids between adjacent filaments of 3D-printed parts affects the adhesion and failure mode of a single-lap joint.

“…Additive manufacturing (AM) or 3D printing has continuously grown in the past years due to its capability to manufacture complex/intricate shapes. It helps people to build real objects using a simple CAD model which led to significant impacts in numerous fields such as food, robotics, dentistry, tooling, medicine, agriculture, optics, electronic, radiation monitoring, water desalination, architecture, art and aeronautics [1]- [10]. 3D printing was originally developed for the creation of prototypes which was deemed too expensive at the time; however, with the recent introduction of low-cost desktop printers in the market, the reputation of the technology has changed and is gradually being accessible to the masses [11].…”

“…AM is composed of various methods which employs different mechanisms to produce the parts. Fused Filament Fabrication (FFF) or Fused Deposition Modelling (FDM) is a 3D printing method that is known to create objects through the extrusion of a melted material in a layer by layer manner [1] [10]. Its printing process starts with a three-dimensional CAD file which is usually in .stl or .obj format.…”

The adoption of Additive Manufacturing (AM) is continuously growing due to its capability to produce complex shapes which leads to the dependence of manufacturers on AM to replace conventional manufacturing processes. One important focus of research now is on the accuracy of 3D printed products produced via the Fused Deposition Modeling (FDM). These products have great potential to be applied to tooling and other rapid prototyping applications. The aim of this study is to assess the accuracy of 3D printed Acrylonitrile Butadiene Styrene (ABS) through manual measurements of dimensions. Several sets of samples with cubic shapes were printed and measured using a digital micrometer to evaluate the dimensional accuracy of the 3d-printed parts. A 22 full factorial design was employed to investigate the effects of infill density and layer thickness on the dimensional accuracy of ABS parts.
