3d scanning applications

Derrumbes y Hundimientos

• Febrary 14, 2003. A maternal school courtyard in Paris fell into the excavations for a new tunnel. This digital-scanned model allowed a precise and detailed investigation which was used as a base for the consecuent data studies and analysis of different experts (geolgysts, builders, and inversors) who could reveal the causes of collapse.

airplane crushing/ spaceships• The collapse of the American space shuttle "Columbia" NASA and Boeing,

organizations responsible for maintaining the space shuttle, have been scanning all parts of the aircraft were found (around 400), and have completely reconstituted with anastylosis virtual method to analyze the causes of the crash of February 1, 2003.

accidents / industrial dangers

• The case of the explosion of various components of a paper machine has demonstrated the effectiveness of laser scanners to find the causes of the accident. The pieces of the two rollers of drying, are scanned one by one. Their virtual reconstruction (anastylosis) allowed the experts confirm that the explosion was caused by the collapse of a steel beam support structure.

earthquakes

• Hokkaido, Japan. September, 2003. [1] An earthquake of magnitude 8.3 on the Richter scale and caused significant damage over three hundred wounded. In order to restore as quickly as possible the rail and road infrastructure, 3D laser scanning is imposed as the analysis tool more quickly and efficiently. The results allowed specialists prepare the necessary repairs to existing software, and refining the results of theoretical simulations when compared with the actual field survey.

crime scenes and traffic accidents

• From a single car accident to the complete registration of a crime scene, the lasser scanning gives a numerical lecture totally comprehensive about the real facts in a precise moment. This 3D footprint may be used to confirm or discard different hypotesis by criminal researchers.

medicine: Axial Computing Tomograhy

• ACT is a healthcare technology X-ray examination that produces detailed images of axial slices of the body. Instead of getting a picture as conventional radiography, CT scan multiple images obtained by rotating around the body. A computer combines these images into a final image that represents a cut of the body like a slice. This machine creates multiple images into slices (cuts) of the body part being studied.

• It is an imaging technique X-ray We could say that is a snapshot of a thin slice obtained after cutting an object.The radiograph is obtained a flat image (two dimensions) of a body (D), running through the same X-ray beam

ACT, operating principle

• The device emits a beam CT X-ray fine This beam impinges on the object being studied and some of the radiation beam passes through it. The radiation is not absorbed by the object in the form of the spectrum, is collected by the detectors. Then the beam emitter, having a specific orientation (eg, strictly vertical to 90 °) changes its orientation (for example, make oblique to 95 degrees). This spectrum is also collected by the detectors.

• The computer 'sum' images, averaging them. Again, the sender changes its orientation (as the example, about 100 ° inclination). The detectors pick up this new spectrum, the 'added' to the above and 'average' data. This is repeated until the ray tube and detectors have come full circle, at which have a definitive and reliable tomographic imaging.

ACT, operating principle

ACT, addvantages & not so much

• Among the advantages of the TAC is found to be a quick test to perform, which offers sharper images that have not yet been overcome with the nuclear magnetic resonance imaging is the visualization of lymph nodes, bone, etc. and among its drawbacks are quoted most often is necessary to use intravenous contrast and that by using X-rays, received doses of ionizing radiation, which sometimes are not negligible. For example in an abdominal CT scan, radiation can be received over 50 chest radiographs, the equivalent of natural radiation over five years.

Now a 3D printer is affordable if you have £2,000 ($3,000 USD)

Fabaroni 3D Printer works with pasta dough (extruder)

The previous test for choosing the right stuff for Fabaroni

• Testing Results

Cheese wiz: too soft, took too long to solidifyChocolate: pretty good viscosity, melted at 90 deg C, took a while to solidifyChocolate sauce: too saucy, didn't solidifyMarshmellow fluff: too thick and too stickyVanilla frosting: too softGummy bears: good viscosity, but takes a while to cool and is stringyGummy bears & Chocolate mix: mixture separatesMarzipan: too thickOiled marzipan: gross, and terrible consistencyPasta dough: good consistency, hardens pretty quickly, flows wellPeanut butter: too runny, too oily

And the winner is...PASTA DOUGH for its good structure and speedy drying properties.
