3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object.[1] In 3D printing, successive layers of material are formed under computer control to create an object.[2] These objects can be of almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.
FDM Process introduction (A part of Additive Manufacturing Technique OR Commonly Known as 3D Printing). 3D printing is an evolved manufacturing technique; it is comparatively better than conventional substractive manufacturing. There is minimum wastage of material because material is added only at those locations where it is required. To make 3D model you need a 3D printer and feeding material and obviously power source. Any thermoplastic material whose melting temperature lies in the range of 150-240 deg. C can be used in FDM based 3D printing.
Autoclave is a closed vessel (Round or Cylindrical) in which processes occur under simultaneous application of high temperature and pressure. Autoclave molding technique is similar to vacuum bag and pressure bag molding method with some modifications. This method employs an autoclave to provide heat and pressure to the composite product during curing.
Wire arc additive manufacturing (WAAM) is a crucial technique in the fabrication of 3D metallic structures. It is increasingly being used worldwide to reduce cost and time. Generally, AM technology is used to overcome the limitations of traditional subtractive manufacturing (SM) for fabricating large-scale components with lower buy-to-fly ratios. It became interesting for scientists and manufacturers due to its ability to produce fully dense metal parts and large near-net-shape products. WAAM is mostly used in modern industries, like aerospace industry. There are three heat sources commonly used in WAAM: metal inert gas welding (MIG), tungsten inert gas welding (TIG), and plasma arc welding (PAW). MIG is easier and more convenient than TIG and PAW because it uses a continuous wire spool with the welding torch. Unlike MIG, tungsten inert gas welding (TIG) and plasma arc welding (PAW) need an external wire feed machine to supply the additive materials. WAAM is gaining popularity in the fabrication of 3D metal components, but the process is hard to control due to its inherent residual stress and distortion, which are generated by the high thermal input from its heat sources. Distortion and residual stress are always a challenge for WAAM because they can affect the component’s geometric accuracy and drastically degrade the mechanical properties of the components.

3D-Bioprinting coming of age-from cells to organsDaniel Thomas
Over the past decade, annual spending on pharmaceutical development to treat many endocrinological systems has increased exponentially.
Currently, preclinical studies to test the safety and efficiency of new drugs, use laboratory animals and traditional 2D cell culture models. Neither of these methods are completely accurate reflections of how a drug will react in a human patient.
A solution has emerged in the form of 3D-Bioprinting technology, developed for the scalable, accurate and repeatable deposition of biologically active materials. With advances in this biomanufacturing technology, durable biological tissues for use in testing new pharmaceutical products are now being harnessed and refined.

L’Internet of Things e i dispositivi indossabili non solo incarnano una tendenza nel campo dell’innovazione, ma rappresentano il futuro del mercato tecnologico. Allo stesso modo, la tecnica di stampa in 3D di parti del corpo umano – sane, migliorate o persino potenziate – ha la capacità di rivoluzionare il contesto sanitario e di riprogettare la condizione umana.
Nell’ambito sia delle wearable technologies sia del bioprinting tra le innovazioni più invasive emergono quelle legate alla realtà aumentata e al potenziamento visivo: Google Glass da un lato, e occhio bionico dall’altro.
L’incontro ha lo scopo di fare chiarezza sullo stato dell’arte e di analizzare le questioni giuridiche ed etiche che possono di fatto porsi come ostacolo alla diffusione di queste tecnologie.

Aspetti legali della stampa 3D: come tutelare una rivoluzione. Stampa 3D: sic...Maria Livia Rizzo
L’improvvisa accelerazione nel mercato della stampa 3D ha di fatto posto il mondo del diritto davanti ad alcune sfide giuridiche di non semplice soluzione. Il fenomeno del 3D printing sta infatti crescendo a dismisura, con il rischio che la rivoluzione dei makers sia ‘in-controllata’, con impatti negativi e rischi per tutta la filiera produttiva e per gli utenti finali. La stampa 3D ha messo in atto il c.d. processo di democratizzazione della manifatturizzazione, facendo entrare in crisi l’attuale sistema di proprietà intellettuale.
Complesse sono anche le implicazioni che tale tecnologia pone nel campo medico, in particolare in relazione alla qualità del prodotto finale e alla sicurezza del processo produttivo. Stampa 3D che comporta infatti rischi causati da dispositivi medici malfunzionanti o possibili danni alla salute derivanti dal processo di stampa o dall’utilizzo del prodotto stampato.
Oggi una soluzione definitiva non esiste. L’esempio di video, musica e libri dovrebbe aver fatto capire tutti che è inutile chiudere i file e adattare i contratti e le leggi vigenti. Innovare non significa adattare, significa capire la tecnologia e ripensare i modelli tecnologici e contrattuali.

Presentation: Conformity Assessment EvidenceTGA Australia
An introduction to conformity assessment procedures for medical devices, good manufacturing practice (GMP), some of the problems commonly experienced by sponsors and TGA, and helpful hints.
Currently worth a few million dollars, the emerging organs-on-chips market has the potential to become a multi-billion dollar market.
Organs-on-chips: the promise of solving one of the pharmaceutical industry’s major hurdles
Bringing a new drug to market is one of the longest and most costly paths any industry has to walk. Companies start with several thousands of compounds that may have positive effects against a disease or a human condition. More than twelve years and several billion dollars later, if they’re lucky they managed to get one of these compounds onto the market. All the others failed at one stage or another during the drug development process – and the later the failure, the more expensive it is. Current methods – cell culture in petri dishes and animal testing among others – are not predictive enough. Around 90% of drugs that have been validated on these models then fail during clinical trials because of toxicity or lack of efficacy. The pharmaceutical industry therefore needs more predictive tools to make drug candidates fail earlier and cheaper. Other industries where toxicity testing is a major concern, such as cosmetics, agro-food and consumer goods, also need such solutions, in particular because animal testing is now banned for these industries in certain geographical areas. Several options have been envisioned, the most promising of which is certainly organs-on-chips. These combinations of micro-technology and biology reconstitute the physiological and mechanical functions of human organs under the form of micro-engineered devices lined with living cells. Precisely controlled fluid flows combined with mechanical cues and tissue-tissue interfaces enable dynamic models, much more relevant than conventional static cell cultures. As a sign of confidence in this technology, significant funding has been allocated to organs-on-chips developers: DARPA and the NIH respectively awarded $140M and $76M over 5-year periods to support developments. In parallel, technology developers have raised more than $80M since 2012 with investors. In Yole Développement’s report, all the key elements to understand the organs-on-chips landscape are detailed.

Lifting the Corporate Veil. Power Point Presentationseri bangash
"Lifting the Corporate Veil" is a legal concept that refers to the judicial act of disregarding the separate legal personality of a corporation or limited liability company (LLC). Normally, a corporation is considered a legal entity separate from its shareholders or members, meaning that the personal assets of shareholders or members are protected from the liabilities of the corporation. However, there are certain situations where courts may decide to "pierce" or "lift" the corporate veil, holding shareholders or members personally liable for the debts or actions of the corporation.
Here are some common scenarios in which courts might lift the corporate veil:
Fraud or Illegality: If shareholders or members use the corporate structure to perpetrate fraud, evade legal obligations, or engage in illegal activities, courts may disregard the corporate entity and hold those individuals personally liable.
Undercapitalization: If a corporation is formed with insufficient capital to conduct its intended business and meet its foreseeable liabilities, and this lack of capitalization results in harm to creditors or other parties, courts may lift the corporate veil to hold shareholders or members liable.
Failure to Observe Corporate Formalities: Corporations and LLCs are required to observe certain formalities, such as holding regular meetings, maintaining separate financial records, and avoiding commingling of personal and corporate assets. If these formalities are not observed and the corporate structure is used as a mere façade, courts may disregard the corporate entity.
Alter Ego: If there is such a unity of interest and ownership between the corporation and its shareholders or members that the separate personalities of the corporation and the individuals no longer exist, courts may treat the corporation as the alter ego of its owners and hold them personally liable.
Group Enterprises: In some cases, where multiple corporations are closely related or form part of a single economic unit, courts may pierce the corporate veil to achieve equity, particularly if one corporation's actions harm creditors or other stakeholders and the corporate structure is being used to shield culpable parties from liability.
