Abstract

The success of laser metal deposition (LMD) for repair or fabrication of near-net shaped metals components directly from computer aided design (CAD) solid models without use of time and cost-prohibitive conventional techniques, such as five-axis milling, linear friction welding and electro chemical machining depends on the availability of a close CAD/ computer aided manufacturing (CAM) chain. Distortion and defects of a worn part implies that the nominal CAD model from the design stage is no longer suitable for the representation of the part geometry. This means that first of all the actual and the target geometry have to be constructed from which the deficit volume is determined. Only with this volume being available the tool paths can be programmed. The original data format of laser scanned data is a polygonal modelling approach for surface representation. The further step of creating a non-uniform rational B-spline (NURBS) representation of the geometry requires a major commitment in time, both in instruction and in amount of work. For this reason the Fraunhofer Institute for Laser Technology (ILT) designed a process chain for the laser material deposition (LMD) whose CAM module termed LMDCAM, is based on a polygonal modelling approach for geometry representation. NURBS are only used for the reduction of data noise in the scanned data. The target geometry of worn parts is derived by a best fit with the CAD model from the design stage. LMDCAM supports the generation of all sorts of path pattern within a layer which for example may be derived from a distortion reduction analysis. The functionalities of LMDCAM are exemplified by a repair application and the near-net fabrication of a blade-integrated disk (BLISK) blade direct from the CAD model. [ABSTRACT FROM AUTHOR]

Abstract

Unlike conventional materials removal methods, additive manufacturing (AM) is based on a novel materials incremental manufacturing philosophy. Additive manufacturing implies layer by layer shaping and consolidation of powder feedstock to arbitrary configurations, normally using a computer controlled laser. The current development focus of AM is to produce complex shaped functional metallic components, including metals, alloys and metal matrix composites (MMCs), to meet demanding requirements from aerospace, defence, automotive and biomedical industries. Laser sintering (LS), laser melting (LM) and laser metal deposition (LMD) are presently regarded as the three most versatile AM processes. Laser based AM processes generally have a complex non-equilibrium physical and chemical metallurgical nature, which is material and process dependent. The influence of material characteristics and processing conditions on metallurgical mechanisms and resultant microstructural and mechanical properties of AM processed components needs to be clarified. The present review initially defines LS/LM/LMD processes and operative consolidation mechanisms for metallic components. Powder materials used for AM, in the categories of pure metal powder, prealloyed powder and multicomponent metals/alloys/MMCs powder, and associated densification mechanisms during AM are addressed. An in depth review is then presented of material and process aspects of AM, including physical aspects of materials for AM and microstructural and mechanical properties of AM processed components. The overall objective is to establish a relationship between material, process, and metallurgical mechanism for laser based AM of metallic components.

One method to fabricate such scaffolds is selective laser sintering (SLS). However, there is a lack of solvent-free prepared microparticles suitable for SLS. Hence, the aim of this study was to develop a solvent-free polylactide/calcium carbonate composite powder with tailored material properties for SLS. Four composite powders with a composition of approximately 75 wt% polylactide (PLLA as well as PDLLA) and 25 wt% calcium carbonate (calcite) were prepared by a milling process based on GMP standards. Four different grades of polylactide were chosen to cover a broad inherent viscosity range of 1.0-3.6 dl/g. The composite material with the lowest inherent viscosity (1.0 dl/g) showed the best processability by SLS. This was caused by the small polymer particle diameter (50 μm) and the small zero-shear melt viscosity (400 Pa·s), which led to fast sintering. The SLS process parameters were developed to achieve low micro-porosity (approx. 2%) and low polymer degradation (no measurable decrease of the inherent viscosity). A biaxial bending strength of up to 75 MPa was achieved. Cell culture assays indicated good viability of MG-63 osteoblast-like cells on the SLS specimens. Finally, the manufacture of 3D scaffolds with interconnected pore structure was demonstrated. After proving the biocompatibility of the material, the developed scaffolds could have great potential to be used as patient-specific bone replacement implants., (Copyright © 2019 The Authors.

Such 3D scaffolds can be manufactured by selective laser sintering (SLS) from biodegradable composite powders. However, the mechanical strength of these scaffolds is often too low for medical application. We propose that the mechanical strength of laser-sintered scaffolds can be improved through composite powders with tailored properties (e.g., suitable powder particle size and melt viscosity for SLS). To prove this, two batches of a poly(D,L-lactide) (PDLLA)/β-tricalcium phosphate (β-TCP) composite powder with 50 wt% PDLLA and 50 wt% β-TCP were synthesized. The two batches differed in polymer particle size, filler particle size, and polymer molecular weight. Both batches were processed with identical SLS process parameters to study the extent to which the material properties influence how well a PDLLA/β-TCP (50/50) composite can be processed with SLS. In the SLS process, batch 2 showed improved melting behavior due to its smaller polymer particle size (approx. 35 µm vs. 50 µm) and its lower zero-shear melt viscosity (5800 Pa∙s vs. 17,900 Pa∙s). The better melting behavior of batch 2 led to SLS test specimens with lower porosity compared to batch 1. In consequence, the batch 2 specimens exhibited a larger biaxial bending strength (62 MPa) than the batch 1 specimens did (23 MPa). We conclude that a tailored composite powder with optimized polymer particle size, filler particle size, and polymer molecular weight can increase the achievable mechanical strength of laser-sintered scaffolds., (Copyright © 2018 The Authors.

Biodegradable stents would provide initial scaffolding of the stenosed segment and disappear subsequently. The additive manufacturing technology Selective Laser Melting (SLM) enables rapid, parallel, and raw material saving generation of complex 3- dimensional structures with extensive geometric freedom and is currently in use in orthopedic or dental applications. Here, SLM process parameters were adapted for poly-L-lactid acid (PLLA) and PLLA-co-poly-ε-caprolactone (PCL) powders to generate degradable coronary stent prototypes. Biocompatibility of both polymers was evidenced by assessment of cell morphology and of metabolic and adhesive activity at direct and indirect contact with human coronary artery smooth muscle cells, umbilical vein endothelial cells, and endothelial progenitor cells. γ-sterilization was demonstrated to guarantee safety of SLM-processed parts. From PLLA and PCL, stent prototypes were successfully generated and post-processing by spray- and dip-coating proved to thoroughly smoothen stent surfaces. In conclusion, for the first time, biodegradable polymers and the SLM technique were combined for the manufacturing of customized biodegradable coronary artery stent prototypes. SLM is advocated for the development of biodegradable coronary PLLA and PCL stents, potentially optimized for future bifurcation applications. </p></dd> <dt class="blacklight-eds_authors col-md-3">Published</dt> <dd class="col-md-9 blacklight-eds_authors">2013</dd> <dt class="blacklight-eds_authors col-md-3"><span class="tags-custom">Full Text</span></dt> <dd class="col-md-9 blacklight-eds_authors"><a class="pdf-blue-icon" target="_blank" href="https://doi.org/10.1007/s10856-012-4779-z">View/download PDF</a></dd> </dl> </article><article data-document-id="cmedm__21495168" data-document-counter="22" itemscope="itemscope" itemtype="http://schema.org/Thing" class="blacklight-academic-journal document document-position-22"> <header class="documentHeader row"> <h3 class="index_title document-title-heading col-sm-9 col-lg-10"> <span class="document-counter"> 22. </span> <a data-context-href="/articles/cmedm__21495168/track?counter=22&document_id=cmedm__21495168&search_id=58504879" href="/articles/cmedm__21495168">Manufacturing of individual biodegradable bone substitute implants using selective laser melting technique.</a> </h3> <div class="index-document-functions col-sm-3 col-lg-2"> <form class="bookmark-toggle" data-doc-id="cmedm__21495168" data-present="In Bookmarks" data-absent="Bookmark" data-inprogress="Saving..." action="/bookmarks/cmedm__21495168" accept-charset="UTF-8" method="post"><input type="hidden" name="_method" value="put" /><input type="hidden" name="authenticity_token" value="9Qgwfwy8Q9kbRlqP7t0dFGSeIkE3eZo528FVcpEYEyw5b0FK6MlGAJTOz26uKqPLGLDHCiTwBqVoEhGNPBgrwg==" /> <input type="hidden" name="catalog_type" id="catalog_type" value="articles" /> <input type="submit" name="commit" value="Bookmark" id="bookmark_toggle_cmedm__21495168" class="bookmark-add btn btn-outline-secondary" data-disable-with="Bookmark" /> </form> </div> </header> <dl class="document-metadata dl-invert row"> <dt class="blacklight-eds_authors col-md-3">Author</dt> <dd class="col-md-9 blacklight-eds_authors mb-0"> <p class="truncate-text"> Lindner M, Hoeges S, Meiners W, Wissenbach K, Smeets R, Telle R, Poprawe R, and Fischer H</p></dd> <dt class="blacklight-eds_authors col-md-3">Subjects</dt> <dd class="col-md-9 blacklight-eds_authors">Calcium Phosphates pharmacology, Implants, Experimental, Lactic Acid pharmacology, Materials Testing, Microscopy, Electron, Scanning, Particle Size, Polyesters, Polymers pharmacology, Porosity drug effects, Powders, Surface Properties drug effects, Absorbable Implants, Bone Substitutes chemical synthesis, Lasers, Tissue Engineering methods</dd> <dt class="blacklight-eds_languages col-md-3">Abstract</dt> <dd class="col-md-9 blacklight-eds_languages"><p class="truncate-text"> The additive manufacturing technique selective laser melting (SLM) has been successfully proved to be suitable for applications in implant manufacturing. SLM is well known for metal parts and offers direct manufacturing of three-dimensional (3D) parts with high bulk density on the base of individual 3D data, including computer tomography models of anatomical structures. Furthermore, an interconnecting porous structure with defined and reproducible pore size can be integrated during the design of the 3D virtual model of the implant. The objective of this study was to develop the SLM processes for a biodegradable composite material made of β-tricalcium phosphate (β-TCP) and poly(D, L)-lactide (PDLLA). The development of a powder composite material (β-TCP/PDLLA) suitable for the SLM process was successfully performed. The microstructure of the manufactured samples exhibit a homogeneous arrangement of ceramic and polymer. The four-point bending strength was up to 23 MPa. The X-ray diffraction (XRD) analysis of the samples confirmed β-TCP as the only present crystalline phase and the gel permeations chromatography (GPC) analysis documented a degradation of the polymer caused by the laser process less than conventional manufacturing processes.
