3D printing or additive manufacturing is the process of making 3D object from digital file. Many different objects (from chocolate to working gun) can be created with 3D printing, and it has been used within many industries such as automotive industry, healthcare industry, aerospace industry, and many more. 3D printing was first known as Rapid Prototyping (RP) in the late 1980s, and it was used in industry to create sample product faster and cheaper. The first patent of RP was developed by Dr. Kodama

IDM Project Assignment: Research 3D Animation production workflow - MAXON C4D When creating a 3d project, there are a number of steps and disciplines involved. And those steps are called 3d pipeline. We first go to the pre-production process of creating artwork to illustrate the look of characters. We will also create storyboards to give role map to follow when creating the shots. From here, we can begin to create all of the models that we are need for animation, this will involve modeling the objects

Animation refers to the creation of the sequence of images drawn, painted, or produced by other artistic methods that change over time portray the illusion of motion. Animators are artists who specialize in the creation of animation. Animation has 2D and 3D, for 2 dimensional figures are created or edited on the computer using 2D bitmap graphics or created and edited using 2D vector graphics. This includes automated computerized versions of traditional animation techniques, for 3 dimensional is digitally

The animation refers to the creation of the images drawn like painted or produced by other artistic methods that can change the illusion of motion. Animators are artists who create of animation. The creator of animated or better known as the animator must use logical thinking to determine the flow of the motion of an object for 2-dimensional figures are created or edited on the computer using 2D bitmap or 2D vector graphics, for 3-dimensional is digitally manipulated by an animator. The animator

3D printing technologies have greatly influenced the advancement of military-related technologies. As 3D printing technologies continue to improve, the complexity of objects that can be produced has been advancing at an unprecedented rate. This has resulted in reduced cost and time required in prototyping as well as in the manufacturing of weapons systems. With 3D printing technology, newer prototyping techniques that are more efficient are now available and thus, the time required to develop new

1.1.1.1 Resin Transfer Moulding (RTM) This process uses a two sided (halves) mould that forms both surfaces of a laminate. The lower side of the mould is made rigid while the upper side is either a rigid or a flexible mould. The two sides fit together to form a mould cavity. With resin transfer infusion the reinforcements are placed into the mould cavity and the cavities are clamped together. Resin is then pumped into the mould, infusing the reinforcement material in the process. Once the mould is

samples of undoped calcium phosphate pellets using various sintering temperature. From the experiment, different sintering temperatures are used such as 1000ºC, 1100ºC and 1200ºC. Each sintering temperature have five samples are being used to measure the density of the samples. After analysis, the average density will be collect and recorded. The summary that can get from the table is the mean density for 1000ºC, 1100ºC and 1200ºC sintering temperature is 3.24, 3.26 and 3.25 each respectively. Based

the preforming departments. 9. Sintering: a) Hydrogen Sintering: A hydrogen atmosphere protects the material from oxidation and reduces some oxides. The hydrogen flow is always in a direction opposite the direction of the material being sintered so as to "sweep" the impurities away. Graphite boats are required and temperatures of between 2500° F and 2750° F are used. All small parts are packed in alundum (Al 2 O 3 ) grain. b) Combination Vacuum Sintering: Pre-sintering is done under inert gas or in

The production stages of mixing and compaction to produce the green compact (sugar-Al powder compact) were exactly the same as in the case of producing pure Al-foams [10,11]. Nevertheless the stages of dissolution and sintering had to be properly adjusted for achieving the carbon coating on the Al-foam. In this case the crystalline raw cane sugar was partially removed from the green compact by water leaching at room temperature. About 70% wt. of the sugar in the green compact was dissolved in water

Powder metallurgy is defined as the process of mixing of powder materials in some desired ratio, compacting the powder mixture to some higher pressures in a compaction die so that the bond formation would takes place followed by the sintering process at higher temperatures (nearly around melting temperatures) so as to achieve sufficient strength. The resulting parts are solid bodies of material with sufficient strength and density for use in diverse fields. Highly porous parts, precise high performance

to shape the orthoses. In recent years, computer-aided design and manufacturing (CAD/CAM) has been increasingly integrated into the field of orthotics and prosthetics. Emerging technologies in 3-dimensional scanning, printing, and selective laser sintering (SLS) offer numerous advantages over traditional methods (Pallari, 2010). CAD/CAM technologies may offer a more cost-effective alternative to the traditional methods of plaster casting and foam impressions (Payne,

Aside from this reaction, there are also two main industrial processes which are used to synthesize this polymer. Manufacturers first begin by synthesizing tetrafluoroethylene (TFE) by amalgamating fluorspar, hydrofluoric acid, and chloroform. These three ingredients are then combined in a chemical reaction chamber which is heated from 590-900 °C. The resultant gas is then cooled and distilled in order to remove any impurities. From there tetrafluoroethylene undergoes either suspension or dispersion

attributes in biocompatibility and biodegrability. The tissue scaffolds are manufactured with many methods, and among them are rapid prototyping techniques, that manufacture the scaffolds in layers. The most common among them is the Selective Laser Sintering, SLS), 3D Printing and stereolithography (SLA), which seem to constantly gain ground in the tissue engineering field.

crystals nucleated and grew. In contrast, when the alkali content was insufficient to produce a significant liquid or glass phase, the Egyptian blue crystals were formed by surface diffusion between the three components, that is, by solid-state sintering. Copper ions are the coloring agent; they are very tightly bound in the stable silicate matrix and cannot be removed easily by chemical and physical means, this tight binding is the key to the high stability of Egyptian Blue

For the last 5 decades, electronics coupled with organic chemistry has been an area of great research interest, especially in physics and chemistry. Until a few years ago, this topic was thought to have no practical approach and was believed to be just research-oriented. Modification of chemical structures so that they can in a way enhance the properties of these when used for electronic applications- especially as a thin film has gained major impetus. It was always thought that organics would soon

LIVER ANATOMY AND PHYSIOLOGY The liver is located in the region of the right upper quadrant of the abdomen (usually does not exceed the limit of the costal margin), filling the space of the diaphragmatic dome, where it can reach up to the fifth rib, and is related to the heart through the center phrenic, to the left of the inferior vena cava. It is usually soft and palpable, and is covered by a fibrous capsule. This fibrous capsule applies peritoneum mainsail liver surface (except liver bare area)

Cranioplasty is the surgical repair of acquired or congenital defects of cranium.[1] Archeological evidences suggest that in prehistorical era , cranial defect reconstruction was done with gold, silver and shells. Later it was followed by the use of bone grafts, metal and plastics.[2,3]Apart from metals like titanium, Polymethylmethacrylate (PMMA) is the latest material being used for cranioplasty. It was first utilized in 1940 and can be moulded intraoperatively by hands or using 3D printed models

3d Printing and its Impact on Society Through Changes in Design and Manufacturing We live in an information age. Huge advancements in science and technology have fundamentally redefined every part of our lives, changing the way we communicate, interact, build and create. It all began with the industrial revolution. The first industrial revolution marked the transition from agrarian handcraft techniques, to the age machines and mass production. Unprecedented growth in science and economics led to
