Additive manufacturing (AM) is a novel technology that enables rapid fabrication of physical models directly from 3D computer-aided design (CAD) data without any conventional tooling or programming requirement. Thermoplastic polymers are the most useful materials for the manufacturing of parts in the FFF process. In this process, extrusion of a semi-molten road through a nozzle is taken place to form each layer, the extruded road solidifies quickly due to the existence of temperature gradient between the surroundings and the extrusion temperature. Different key parameters affect the final products manufactured by this process. These parameters can be listed in three categories. Some of them are linked to the material, others are linked either to the characteristics of the process or to the specificity of the machine. They can influence the properties of the final part through their effect on various physical phenomena. The mentioned parameters affect the polymer temperature and its evolution. It is important to know the evolution of filaments temperature with time and recognize how it is affected by major process variables as mentioned. Due to the nature of the FFF process, it is important to measure the temperature profile and its evolution during the process by the means of local measurement methods. The idea of this work took place in 2018, by start reviewing literatures related to the FFF process. As mentioned, almost all studies and works either numerical or experimental approaches were based on global consideration. In the beginning, the work was concentrated on finding a method to be applied to the FFF process to proceed with the localized investigation. Afterward, the experiment was started to see the possibility of the work. As in the FFF process, there is a deposition of filaments, and each filament itself is heated by the deposition of newer filaments, there is almost a cyclic evolution of the temperature due to multi-layer d eposition and it means that each filament is re-heated consequently because of the deposition of a new filament. This is a critical issue in creating a filament bonding and diffusion of materials. To implement and measure this cyclic temperature, it is required to apply a measurement device in which to be capable of measuring the temperature of the polymer when leaving the nozzle. One can note that the mechanical properties of 3d-printed pieces are limited. In this work, we try to improve the mechanical properties by reinforcing the fibers such as glass fibers, carbon fibers, etc. At the same time by controlling the temperature evolution, we try to improve the adhesion between the layers to have the best structure. The used material as raw material was polyamide-6 (PA6). The main objective of this research is to study the rheological characteristics of materials during FDM/FFF to process optimization for mechanical characterization improvement of the fabricated parts. Therefore, the main objective is to take into account both the temperature and viscosity parameters, and to establish the Time-Temperature-Transformation diagram for process optimization. This helps to determine the processability area

Ett hinder för att additiv tillverkning (AT), eller ”3D-printing”, ska få ett bredare genomslag är svårigheten att uppskatta effekterna av processparametrar på den tillverkade produktens mekaniska prestanda. Det komplexa förhållandet mellan geometri och processparametrar gör det opraktiskt och komplicerat att härleda analytiska uttryck för att förutsäga de mekaniska egenskaperna. Alternativet är att istället använda numeriska modeller. Huvudsyftet med denna avhandling har därför varit att utveckla en numerisk modell som kan användas för att förutsäga de mekaniska egenskaperna för detaljer tillverkade genom AT. AT-tekniken som avses är inriktad på Fused Filament Fabrication (FFF). En numerisk modell har utvecklats genom att återskapa FFF-byggprocessen i en simuleringsmiljö. Instruktioner (skriven i GCode) som används för att bygga en detalj genom FFF har här översatts till en numerisk FE-modell. Modellen används sen för att bestämma effekterna av processparametrar på styvheten och styrkan hos den tillverkade detaljen. I detta arbete har strukturstyvheten hos olika detaljer beräknats genom att utvärdera modellens svar för jämnt fördelade belastningsfall. Styrkan, vilket är starkt beroende på den tillverkade detaljens termiska historia, har inte utvärderats. Den utvecklade numeriska modellen kan dock fungera som underlag för implementering av modeller som beskriver relationen mellan termisk historia och styrka. Den utvecklade modellen är anpassad för optimering av FFF-parametrar då den omfattar effekterna av alla FFF-parametrar. En genetisk algoritm har använts i detta arbete för att optimera parametrarna med avseende på vikt för en given strukturstyvhet.

I det här kandidatarbetet undersöker jag hur automatisering inom fused filament fabrication (FFF) kan implementeras, och vad begränsningarna är för olika sorters automatiseringslösningar för FFF. Det läggs även fram en uträkning för den kommersiella gångbarheten för small batch rapid production med implementeringen av ett automatiskt FFF-system. Tillvägagångsättet bestod av en kvalitativ studie baserad på fem intervjuer, kombinerad med empirisk kunskap och data från additiva tillverkningsföretaget Svensson 3D. Det här kompletterades med en analys av vilka parametrar som bör användas för att utvärdera lösningar för FFF-automatisering, och ett ramverk där automatiseringslösningarna betraktas ur ett operatörs-perspektiv. För att räkna ut den kommersiella gångbarheten för automatiseringslösningar av FFF användes internränta och återbetalningstid. Det här resulterade i sex parametrar för att utvärdera automatiseringslösningar för FFF, tre utvärderingar av vilka problem som finns i tre existerande automatiseringslösningar, och slutsatsen att small batch rapid production är kommersiellt gångbart för automatiserad FFF. Slutligen innehåller arbetet en diskussion gällande framtiden för FFF och begränsningarna hos det ramverk som presenterades för att utvärdera automatiserade FFF system. Möjliga lovande lösningar för automatiserad FFF presenteras och hur design för additiv tillverkning kan hjälpa till att forma framtiden för automatiserad FFF.

Endovascular repair (EVAR) of an abdominal aortic aneurysm (AAA) involves the placement into the aneurysm of a stent graft (SG) by minimally invasive surgery. This procedure prevents rupture of the damaged tissue involved in an AAA, defined as a localized diameter dilation of the aorta. When the upstream portion of the aneurysm includes the peripheral renal and/or visceral arteries, the AAA is qualified as complex. In this case, the deployed SG is said “fenestrated”, in other words, perforated at the site of junctions to the peripheral arteries. Management of a complex AAA becomes more limiting as the fenestrated SG will be custom designed to match the anatomy of the aneurysm and the position of the peripheral arteries of the patient. This implies a manufacturing delay of several weeks, limits the management to stable aneurysms and excludes emergency situations. In this context, 3D printing (3DP) is of considerable interest for the fabrication of custom-made SGs in a very short time frame. Thus, the objective of this thesis work is to design a SG prototype by 3D printing of a medical grade thermoplastic polyurethane (TPU) (thermoplastic elastomer). The present work will validate the manufacturing process and the functionality of our 3DP-SG for its final application as an implantable medical device.First, the impact of the manufacturing process on the chemical, physical and physicochemical properties of TPU was studied at each step, from the pellets to the gamma-ray sterilization of a graft manufactured by fused filament deposition (FDM). In vitro preliminary evaluation of the cytotoxicity and hemocompatibility of TPU was carried out after the 3D printing and sterilization step. Aging of TPU under extreme oxidizing conditions was performed to predict the evolution of its properties in the long term. Subsequently, a design strategy for an endovascular implantable prototype was developed. The properties of said prototype were characterized by different techniques (SEC, TGA, DSC, FTIR, SEM, goniometry, uniaxial traction, ...). Its biological properties were evaluated in vitro by tests of cytocompatibility, hemocompatibility and contact with macrophages for 24 hours (acute inflammation). Moreover, the evolution of its physicochemical and mechanical properties was evaluated by in vitro aging studies.The characterization of the chemical, physical and physicochemical properties of TPU enabled the validation of a FDM printing manufacturing route and gamma ray sterilization of a crimpable SG prototype. The in vitro biological evaluation showed the non-cytotoxicity of the SG prototype by the extraction method. Moreover, the prototype was found to be weakly hemolytic and the platelets adhered on its surface were not activated. The low secretion of cytokines (IL-6 and TNF-α) upon contact with inactivated macrophages showed that the SG prototype does not exhibit a pro-inflammatory characteristic. Finally, aging studies showed an impact on the mechanical and surface properties of our SG prototype without compromising its functionality. Subsequently, the design strategy could evolve towards a functionalization of the SG prototype in order to prevent infections and thrombosis responsible for 2% and 6% of postoperative complications respectively

Additive manufacturing (AM) has become a new option for the fabrication of metallic parts in industry. However, there are still some limitations for this application, especially the unfavourable final shape and undesired macroscopic properties of metallic parts built in AM systems. The distortion or crack due to the residual stress of these parts leads usually to severe problems for some kinds of metal AM technology. In an AM system, the final quality of a metallic part depends on many process parameters, which are normally optimized by a series of experiments on AM machines. In order to reduce the considerable time consumption and financial expense of AM experiments, the numerical simulation dedicated to AM process is a prospective alternative for metallic part fabricated by additive manufacturing. Because of the multi-scale character in AM process and the complex geometrical structures of parts, most of the academic researches in AM simulation concentrated on the microscopic melting pool. Consequently, the macroscopic simulation for the AM process of a metallic part becomes a current focus in this domain. In this thesis, we first study the pre-processing of AM simulation on Finite Element Method (FEM). The process of additive manufacturing is a multi-physics problem of coupled fields (thermal, mechanical, and metallurgical fields). The macroscopic simulation is conducted in two different levels with some special pre-processing work. For the layer level, the reconstruction of 3D model is conducted from the scan path file of AM machine, based on the inverse manipulation of offsetting-clipping algorithm. For the part level, the 3D model from CAD is reconstructed into a voxel-based mesh, which is convenient for a part with complex geometry. The residual stress of a part is analysed under different preheat temperatures and different process parameters. These simulations imply the potential technique of reducing residual stress by the optimisation of process parameters, instead of the traditional way by increasing preheat temperature. Based on the FEM simulation platform above, two simulations at line level are also studied in this thesis, aiming at the relation between the AM process and part's final quality. These examples demonstrate the feasibility of using macroscopic simulations to improve the quality control during the AM process. In the first task, dataset of heating parameters and residual stress are generated by AM simulation. The correlation between them is studied by using some regression algorithm, such as artificial neural network. In the second task, a PID controller for power-temperature feedback loop is integrated into AM process simulation and the PID auto-tuning is numerically investigated instead of using AM machine. Both of the two tasks show the important role of AM macroscopic process simulation, which may replace or combine with the numerous trial and error of experiments in metal additive manufacturing
