The prototype of a newly developed 3D printer is able to process commercial pellets – also those of high-performance plastics such as PEEK, PPS, PSU, PA and PC, with or without fibers. The machine applies the usual strand-deposition process, though with a simply designed print head that includes a radial screw. Note de contenu : - Downsides of filament printers
- Print head for an ingenious twist
- Axial approach bound to fail
- What makes welded joints so strong
- Unbeatable price

Attached to a disk, the spiral drives the plastic from the outside to the inside, towards the nozzle outlet. A force acting upon the disk from above controls the pressure between disk and the opposite area where the outlet is, and therefore the plastic extrusion process itselfEn ligne : https://drive.google.com/file/d/1DpJZLjTMehJCKGfEFpSfURhfWLb-TWf9/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29284

Traction (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : Additive Manufacturing (AM) technologies have been emerged as a fabrication method to obtain engineering components within a short span of time. 3D printing, also referred as additive layer manufacturing technology is one of the powerful methods of rapid prototyping (RP) technique that fabricates three-dimensional engineering components. fused deposition modelling (FDM) is one of the most commonly used additive manufacturing (AM) methods, with applications in modelling, prototyping, and production. Acrylonitrile–butadiene–styrene (ABS) is a widely used industrial thermoplastic that is also the most commonly used material in FDM technology. Understanding the impact of FDM build settings on material characteristics is essential for predicting the behaviour of ABS components. The purpose of this study is to determine the impact of specimen tensile and compressive behaviour on ABS components produced using FDM. The Ultimaker+2 printer is used to create ABS thermoplastic samples for the investigation. The samples are put through their tests using a modified form of ASTM D638 for tensile strength and ASTM D695 for compressive strength. An Instron testing machine is used to put the printed parts to the test. The approach employed was Design of Experiment (DOE). Three primary criteria are used in the plastics experiment: infill density, layer thickness, and infill pattern. We measured the tensile and compressive strengths of zigzag and gyroid specimens, as well as cross specimens. The highest compressive strength at break (25.01 MPa), Young's modulus (2.473 GPa), fracture strength (21.016 MPa), and ultimate tensile stress (23.1 MPa) were all discovered in a sample with 60% infill density, 0.05mm layer thickness, and a GYROID infill pattern.

Terpolymère acrylonitrile butadiène styrèneIndex. décimale : 668.4 Plastiques, vinyles Résumé : The high strength and low weight requirements of advanced land, air and sea vehicles are obtained by taking advantage of sandwich panel structures. The low density cores used are limited to feasible topologies by current manufacturing techniques. Fused deposition modeling combined with electroforming removes the manufacturing limitations and creates topologies with comparable mechanical properties to conventional cores. Tetrahedral, pyramidal and strut reinforced tetrahedral (SRT) unit cell topologies will be optimized for specific strength. The response of fused deposition acrylonitrile butadiene styrene (ABS) plastic cores will be presented. In addition, scaling experiments such as 3D scaling and slenderness ratio scaling will be conducted on a unit cell analysis. Note de contenu : - Ideal slenderness ratio
- Core generation
- Mechanical testing
- Analysis
- Vertical height scaling
- Relative density (slenderness ratio)
