Recently, the possibility of producing medium-to-large batches has increased interest in polymer powder bed fusion technologies such as selective laser sintering (SLS) and multi jet (MJF). Only scant data about characterization parts produced by MJF can be found literature, fatigue behavior studies are absent. This study analyzes material properties Polyamide 12 (PA12) powders printed specimens using both SLS technologies. The morphology, crystalline phases, density, porosity, dimensional...
Abstract Soundness of additively manufactured parts depends on a lot process and geometrical parameters. A wrong design leads to defects such as lack fusion or keyhole porosity that have detrimental effect the mechanical properties printed parts. Process parameter optimization is thus formidable challenge requires in general huge amount experimental data. Among others, heat source power scan speed are most defects-affecting parameters be optimized. The energy density used literature quantify...
To compare the flexural properties and adhesion of Lactobacillus salivarius (LS), Streptococcus mutans (SM), Candida albicans (CA) on heat-polymerized (CV), CAD-CAM milled (CAD), or 3D-printed (3D) Poly (methylmethacrylate) (PMMA).Ultimate Flexural Strength (UFS), Strain (FS) (%) at Strength, Modulus (FM) specimens (65.0×10.0×3.3 mm) from each PMMA group (n=6) were calculated by using 3-point bending test. The surface roughness profiles (R) measured before after polishing with a contact...
Improving soft tissue attachment and reducing bacterial colonization on titanium abutments are key factors for the long-term maintenance of healthy hard peri-implant tissues. This in vitro study was conducted to compare biocompatibility antibacterial activity four different surfaces: uncoated Ti6Al4V, anodized, coated with nitride or zirconium nitride. Surface topography investigated a high-resolution system measuring surface finishes. Human gingival fibroblast (HGF) adhesion proliferation...
The purpose of this study was to investigate the marginal precision computer numeric control-milled frameworks fabricated grade 4 commercially pure titanium or cobalt-chrome alloy through digital technology and compare them with conventional cast frameworks.A a mandibular arch six implant analogs used as master. master measured coordinate measuring machine. Fifteen rigid anatomic were created on in gold milled material. fifteen same manner cast. While once, at end milling process, twice:...
Purpose This paper aims to propose a consistent approach geometric modeling of optimized lattice structures for additive manufacturing technologies. Design/methodology/approach The proposed method applies subdivision surfaces schemes an automatically defined initial mesh model arbitrarily complex structure. has been developed cubic cells. Considering different aspects, five have studied: Mid-Edge, original scheme by the authors, Doo–Sabin, Catmull–Clark and Bi-Quartic. A generalization other...
Additive Manufacturing (AM) brought a revolution in parts design and production. It enables the possibility to obtain objects with complex geometries exploit structural optimization algorithms. Nevertheless, AM is far from being mature technology advances are still needed different perspectives. Among these, literature highlights need of improving frameworks that describe process taking full advantage possibilities offered by AM. This work aims propose workflow for guiding designer during...
Digital workflows have revolutionized dentistry, especially when it comes to fabrication of complete dentures through Computer-Aided Design and Manufacturing (CAD-CAM) procedures. articulators manage simulate mandibular movements are emerging as alternatives mechanical like the Gerber semi-adjustable model. Despite being a promising tool, digital require refinement in order grant consistent functionality effective occlusal balance. The aim this research is present semi-automated MATLAB tool...
Abstract Virtual assembly has become a popular trend in recent years and is used for various purposes, including selective adaptive tooling. Monte Carlo approaches based on Finite Element Method (FEM) simulations are commonly production applications. However, during the design phase, when testing different configurations options, variational method more suitable. This paper aims to test implementations of System Moments applied second-order tolerance analysis actual distributions, which...
