3d Scanning Services

We all live our busy lives going day to day doing the things we have to do or love to do.  How often do you stop and think about the price paid for the freedom we all have?  With tensions rising in foreign countries recently it reminded me of the price paid by our veterans and current military personal in keeping us safe and protecting those freedom.

We recently just finished another scanning project involving some of our those heroes and we also had a chance to visit Orlando’s Veterans Memorial Park and see a Vietnam War Memorial we had worked on.  The final bronze casting was put in place at the memorial and it was quite moving to actually see the final product.

EMS worked with American Bronze Foundry in Sandford, FL to 3D scan the original model, make changes to it and scale it up to over 9 feet in size.  What was a little different for this project is the original model was not sculpted from clay or foam to begin with.  It was a pair of mannequins dressed in military outfits.  The group raising the money to have the memorial created needed a replica of the statues to go out and raise money.  They decided to build their own replica and take it on the road raising the money need to build the memorial.

Last week, we introduced you to 3D scanning technology and all of its many uses. This week, we’re going to focus on how it actually works with technical specifications sure to appease even the most detail oriented among us.

These scanners work in a variety of different ways but there are some aspects that are applicable across all different types. If short-range scanning is your goal, then you are likely talking about laser triangulation or structured light scanners. Laser triangulation involves the use of a laser line or point that runs across an object at close range. A sensor calculates the amount of light reflected off the object in order to draw a dot map of it on a computer. The other type of short range 3D scanning is structured light. It uses white or blue light to project patterns onto an object. The edges of each line is measured and the distance between the scanner and object is recorded to create a three-dimensional image.

Is there anything 3D scanning technology can’t do? That ought to be the question. Still, if you’re interested in this area of advancement, you’ve come to the right place. We’re going to spend the next two posts discussing what it is, how it works, and why you should definitely care about how it progresses over the next few years.

For starters, you might be wondering what a 3D scanner is, exactly. Let’s break it down. A 3D scanner is a device that can measure an object or its surroundings using lights, laser, or x-rays. It creates point clouds or polygon meshes depending on where the light/lasers hit the object in front of it. These data points are then fed into a computer and processed to create a three-dimensional rendering of the physical object or space.

Now let’s think about some of the things this technology is used for. Right this very second, people are using 3D scanning to record data about parts of equipment and devices like vehicles, aircraft, and machinery that may not currently have a digital blueprint available. This makes it much simpler for engineers to then update designs and make modifications.

You already know by now that 3D scanning technology has a multitude of uses. But did you know it’s currently being used by NASCAR? That’s right! The racecar conglomerate is now using this tech to streamline vehicles and encourage even faster speeds along the racetrack. And when the cars already barrel down at nearly 200 mph, that’s pretty impressive!

Speed is absolutely everything in a NASCAR race and since the winners are determined often by less than a tenth of a second, going faster is the ultimate imperative. Each stock car must follow specific guidelines, however. This is why NASCAR teamed up with BMI Corporation to further improve aerodynamics while sticking to said guidelines. They ended up using the Rapidform XOR in the process as well.

As a part of the process, they’re using CFD to visualize what changes need to be made in order to get faster speeds. While other teams use wind tunnels, NASCAR is using CFD simulations. To get the vehicle data in the program, however, they’re using the Rapidform XOR, which is a piece of 3D scanning equipment from Konica Minolta. Paired with two CFD programs from Boeing, the combination is a winner. The scanner builds a point cloud of an entire vehicle then Rapidform creates surface information.
