ABSTRACT Hybrid additive manufacturing consists of upgrading wrought material by an process, adding stacked layers through the melting and sintering a different powder. A literature survey indicates that fatigue data for hybrid additively manufactured parts are currently missing. This paper is focused on response 1.2343 hot work steel, upgraded maraging steel MS1 powder processed laser bed fusion, finally heat‐treated complying with specifications from supplier. Results, supported microscopy...
ABSTRACT The effect of part build orientation on the fatigue properties additively manufactured parts has been demonstrated to be highly influenced by type or composition raw material. In this study, an experimental campaign was carried out investigate in case CX maraging steel processed laser powder bed fusion. For purpose, specimens were with vertical, horizontal, and 45° inclined orientations. First, dimensional accuracy, surface finishing, density, hardness characterized determine role...
This study investigates the effect of shot-peening on bearing friction coefficient 42CrMoV grade 14.9 screws. An experimental campaign was conducted a tribological testing rig, investigating combined effects shot peening treatments, lubrication conditions, and number tightenings frictional coefficient. A first set tests performed, considering same conditions as in previous to highlight role different material. second carried out, adjusting process parameters enhance response. Small shots...
Abstract Although extensive research has been carried out on the effects of temperature properties parts by fused filament fabrication, no study considered opportunity to use different temperatures and cooling strategies for contour infill region. The purpose this investigation is explore such an through experimental campaign polylactic acid. Specifically, variations in tensile warping occurring with methods are documented. results demonstrate that diversifying process parameters used part...
Abstract The adoption of natural‐based fibers in place inorganic reinforcements is an effective approach to reduce the environmental and economic impact composite materials. In particular, hemp attractive solution due its mechanical, physical, growing properties. present article deals with manufacturing thermoset hemp‐reinforced investigation moves into production by resin transfer molding powder use epoxy polymeric material. To describe effects technological cycle onto characteristic...
Purpose The body of the literature on Arburg Plastic Freeforming process is still very limited despite increasing industrial importance this technology. This paper aims to contribute a better understanding technology by investigating relations between characteristic parameters and part features. Particularly, effects nominal dimension, drop aspect ratio, build chamber temperature position accuracy are investigated. density manufactured parts also measured understand its relation with...
Purpose Multi jet fusion is an industrial additive manufacturing technology characterised by high building speed and considerable properties of the parts. The cooling phase represents a crucial step to determine productivity, since it can take up 4.5 times time. purpose this paper investigate into effects rate on parts manufactured multi fusion. Crystallinity, density, distortions mechanical specimens produced through HP 4200 are examined. Design/methodology/approach An experimental activity...
Lubrication is essential to ensure the proper performance of threaded joints subjected multiple tightenings. Previous research has investigated effectiveness various mineral and synthetic lubricants, but no studies have been conducted on those derived from renewable sources. In this study, performances sesame, sunflower, coconut, castor oil are compared traditional VG46 MoS2 grease. First, rheological properties oils characterized. Then, tightening tests carried out measure coefficients...
Additive Manufacturing includes a number of techniques that combine specific equipment with certain materials but some common principles concerning the product design and aspects related to manufacturing optimisations can be identified. Amongst these principles, process parameters are included contribute determining environmental sustainability engineering products and, in particular, affect their Life Cycle Impact Assessment. This paper aims provide method find out build orientation for...
