ABSTRACT Parts produced by extrusion‐based additive manufacturing experience the disadvantage of consisting many weld‐lines, which consequently downgrade their mechanical properties. This work aims at maximizing strength printed parts considering and improving intra‐ inter‐layer cohesion between adjacent strands. Therefore, poly(lactic acid) specimens were characterized means a particular tensile test setup, was evaluated double cantilever beam test. A detailed parametric statistical...
A major challenge in extrusion‐based additive manufacturing is the lack of commercially available materials compared to those well‐established processes like injection molding or extrusion. This study aims at expanding material database by evaluating feasibility polypropylene, which one most common and technologically relevant semicrystalline polymers. Expanded‐perlite‐filled polypropylene ternary blends with amorphous polyolefins are evaluated establish an understanding their processability...
Abstract A challenge in extrusion‐based additive manufacturing of polypropylene (PP) filled with spherical particles is the combination decent processability, excellent warpage control, and retention tensile strength neat PP. This study addresses this issue by adopting two approaches. Firstly, different size fractions borosilicate glass spheres incorporated into PP are compared. Secondly, temperature printing chamber ( T Ch ) varied. The effects these features on thermal, crystalline,...
Polypropylene (PP) parts produced by extrusion‐based additive manufacturing (EB‐AM) suffer from warpage issues due to their high degree of crystallinity and orientations introduced during printing. These can be overcome the addition spherical fillers. However, low aspect ratio filler filling degrees necessary for preventing downgrade mechanical properties, especially toughness. This study aims at optimizing a PP‐compound containing glass microspheres application in EB‐AM maximizing...
Due to a lack of long-term experience with burgeoning material extrusion-based additive manufacturing technology, also known as fused filament fabrication (FFF), considerable amounts expensive will continue be wasted until defect-free 3D-printed component can finalized. In order lead this advanced technique toward cleaner production and save costs, study addresses the ability remanufacture wide range commercially available filaments. Most them either tend degrade by chain scission or...
Additive manufacturing (AM) has revolutionised the industry, offering versatile capabilities for creating complex geometries directly from a digital design. Among various 3D printing methods polymers, vat photopolymerisation combines photochemistry and printing. Despite fact that single-epoxy been explored, fabrication of multi-material bioderived epoxy thermosets remains unexplored. This study introduces feasibility potential by means dual-vat Digital Light Processing (DLP) technology,...
Polyethylene pressure pipes are designed for service lives of at least 50 years. While so far lifetimes have been assessed by pipe tests, due to improved slow crack growth (SCG) resistance and increased testing times such tests not suitable anymore modern grades. The paper presents an alternative methodology lifetime prediction, combining practical advantages the cyclic cracked round bar (CRB) test linear elastic fracture mechanics. A major advantage this procedure is that material...
Material extrusion additive manufacturing (MEX) is a versatile technology for producing complex specimens of polymers, ceramics and metals. Highly-filled filaments composed binder system high-volume content sinterable powders are needed to produce ceramic or metal parts. After shaping the parts via MEX, removed sintered obtain dense part filler particles. In this article, applicability process copper demonstrated. The particular emphasis on investigating production lightweight that retain...
Additive manufacturing is a useful tool for fabricating complex multimaterial structures. Compliant interlayers (ILs) can easily be introduced into stiff materials to increase toughness and stop or impede crack growth, as done in nature. The aim herein analyze the influence of varying IL lengths thicknesses on propagation 3D‐printed polymers at different loading rates. A glycol‐modified poly(ethylene terephthalate) used matrix material, while thermoplastic elastomer copolyester basis serves...
Polyetheretherketone (PEEK) is considered a 'gold-standard' material choice for cranial bone reconstruction. The introduction of additive manufacturing (AM) into the pipeline patient specific implant (PSCI) fabrication could accelerate supply chain needs and improve outcomes. Fused filament (FFF), extrusion-based technology, much-researched process due to its accessibility ease use. However, quality PEEK processed by FFF highly affected applied printing profile. Therefore, in this study,...
