“…Polycarbonate (PC) is widely employed in medical, aerospace and automotive because it is one of the most important industrial plastics. It is worth noting that further studies are required to investigate the applications for other polymers such as PC [23], polycarbonate/acrylonitrile butadiene (PC-ABS), polyphenylsulfone (PPSF), antibacterial nylon [24] and polylactic acid (PLA) [25].…”

Additive manufacturing (AM) is the process of fabricating three-dimensional physical models by layered manufacturing without the need of molds or dies. Surface finish of AM physical models is not satisfactory for most general engineering purposes. The aim of this study is to develop an acetone-vapor polishing system to smooth acrylonitrile butadiene styrene (ABS) parts fabricated by fused deposition modeling. Acetone vapor dissolved the outer surface of ABS parts and the surface roughnesses of ABS parts with complex geometries can be significantly reduced. The advantages of this system include flexibility to maintain dimensional accuracy, high polishing efficiency, low equipment costs, and no waste chemicals compared to conventional approaches.

“…A preliminary design was established using six injection parameters: the material temperature ( T ma ), the injection pressure ( P inj ), the holding pressure ( P h ), the mold temperature ( T mo ), the holding time ( t h ), and the cooling time ( t c ). Reference values and range of variation were taken from the previous works on PC/ABS blend, the material data sheet, and the SKG experience. The parameters related to the injection machine capacity were the mold temperature ( T mo ), the injection pressure ( P inj ), and the holding pressure ( P h ).…”

Polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) possess thermal and mechanical properties, which make them materials of choice for automotive components. These properties have presented PC/ABS as an eligible replacement for metals in automotive industry. The aim of this study was to explore a new approach to determine the optimum conditions for obtaining quality and shear stresses of the injected and metalized PC/ABS parts. For this purpose, the following six injection-molding parameters such as material temperature (T ma ), injection pressure (P inj ), holding pressure (P h ), mold temperature (T mo ), holding time (t h ), and cooling time (t c ) were considered at four different values. The effect of the injection parameters studied has been analyzed through the quality and the shear stresses values of the injected and metallized PC/ABS specimens. Optical microscopic and confocal laser scanning microscope (CLSM) results demonstrate that the occurrence of some defects such as weld line, blister, poor adhesion, metal residue, sand scratch. Moreover, scanning electron microscope (SEM) findings show the presence of core defects and solidified pellets. Shear stresses vary between 3.78 and 5.8 MPa for the injected specimens and 4.5 and 6.4 MPa for the metallized specimens. The optimum injection parameter combinations were conditioned by producing flawless injected and metallized PC/ABS parts having a significant shear stress value. Thus, the optimum combinations consists of: a T ma of 260 C, a P inj ranging between 30 and 50 bar, a P h ranging between 20 and 25 bar, a T mo of 40 C, a t h ranging between 8 and 14 sec. and a t c of 25 sec. These findings may have interesting applications in automotive part industry.

3D-MID Technology for Surface Modification of Polymer-Based Composites: A Comprehensive Review

et al. 2020

View full text Add to dashboard Cite

The three-dimensional molded interconnected device (3D-MID) has received considerable attention because of the growing demand for greater functionality and miniaturization of electronic parts. Polymer based composite are the primary choice to be used as substrate. These materials enable flexibility in production from macro to micro-MID products, high fracture toughness when subjected to mechanical loading, and they are lightweight. This survey proposes a detailed review of different types of 3D-MID modules, also presents the requirement criteria for manufacture a polymer substrate and the main surface modification techniques used to enhance the polymer substrate. The findings presented here allow to fundamentally understand the concept of 3D-MID, which can be used to manufacture a novel polymer composite substrate.
