The Daily 3D Detail: 3D scanner water tank

Posted by Taila Rodrigues On August - 3 - 2017

The traditional 3D scanner methods are based on optical devices, laser and cameras.

Researchers have discovered an unusual scanner method, a 3D scanner immersed in water tank. The object is immersed in a water bath by a mechanical arm, in order to obtain a better reconstruction the object needs to be immersed many times, in this way the water and able to penetrate in all the areas of the object, are also submerged from different angles through of which measures the elevation of water.

This method accurately reconstructs even hidden parts of an object that typical 3D laser scanners are not able to capture.

The team based their method on the ancient principle of Archimedes‘ displacement – the volume of displaced fluid is equivalent to the volume of a submerged object.

The team approach is safe and economical, it is a low cost alternative using an innovative method.

Next year’s event only promises to be more engaging

The most important thing you need to do right now is book travel and lodging to be in Pasadena, California between the dates of May 22-24, 2018. That is when SpaceTech Expo is happening at the Pasadena Convention Center and you will not want to miss it. Bring the kids. This event deserves the Governor’s Award for STEM Development. It’s the closest thing anyone can get to hanging out with astronauts themselves. All the people there are all qualified geniuses. And they are developing technology you want to discover. It’s nothing short of awe-inspiring.

The show had something for everyone at any age

Why Pasadena? Because that’s where Caltech resides. And anyone who knows will tell you that you have a satellite’s chance in the sun of getting into JPL without having graduated from Caltech with honors. Space exploration lives here.

3D Printing at SpaceTech Expo

Every aspect of space exploration was displayed for people to experience first-hand

SpaceTech Expo is expanding like the universe. The vast number of booths and offerings of this year’s expo were too numerous to mention in full. We had to limit this article to 3D printing specifically. We begin with GoEngineering.

3D Printing at SpaceTech Expo

GoEngineering’s 3D printing specialist Glen Chancellor demonstrates the Creaform’s ease of use

GoEngineering displayed their HandyScan Creaform scanner integrated with their editing software VX Elements to maximize their position in the scanning market, and frankly, they may be succeeding. Their device is barely over a pound and scans an object to within 30 microns of accuracy. Perfect for reverse engineering any spacecraft. It’s like waving around a baggie ziplocked with air. It’s LASER beams are precise, producing 480,000 measurements a second which is harmless to human exposure, and amazingly accurate. Patching the holes in the VX Elements software was a piece of cake. If I was running a city crime lab looking for the best means of recording forensic evidence, I would snag two for busy days. Price? $35,000.

The scanner market is huge. Huger than huge and few have grasped the importance of it’s impact on the future economy. Read driverless cars. Companies that get that will succeed for sure. SpaceTech taught us that this year.

Contributing Editor Fred Kaplan on scanning: “3D scanners produce point clouds of positional data. The point clouds are geometric samples of the object being scanned and often contain billions of points which require software to optimize the data and to export the data to a solid model such as a .STL file. 3D scanner software can smartly interpolate the point cloud to fill holes, merge meshes, optimize meshes, decimate meshes and create water-tight models ready to be 3D printed.

“3D scanners divide into two types of technologies. Laser Scanners that use a laser source that defines space by emitting laser light from two sources and recorded on camera in a process called triangulation and Touch probes or contact scanners recording positional data in 3D space by touching the surface of the object and clicking the device. Another technology that is used to record the surface imagery and the geometry of an object is call photogrammetry. Photogrammetry used an array of still cameras all pointed at an object or person. Software aligns the images, creates a visual reproduction of the surface and interpolates the geometry. Photogrammetry is used to create human reproductions because the process is recorded the duration of still camera shutter. There are also a variety of medical applications such as CT scans that are scans based upon the volume of an object.”

To be specific, understanding the scanning market takes foresight:
3D scanning is used in:
1) Inspection: to measure the size of an actual part to compare to the CAD that was original designed to increase the accuracy of the part and quality control.
2) Engineering: Creating CAD from an existing part to re-create something no longer being produced or to adapt something new from something old or replace old parts
3) Product Development: Feet and faces are commonly scanned for sizing shoes or eye glasses
4) Medical applications
5) GIS, mapping
6) LIDAR in autonomous cars

GoEngineering’s William Huertas shows how their software makes Creaform so effective

Kaplan went on: “Creaform scanners are hand-held that are fast and easy to use. The HandyScan scanner is made to scan the interior or the space stations as well as the auto, healthcare and manufacturing applications. The company originated as a scanner service provider but the HandyScan and GoScan packages have set the standard as the highest quality handheld scanners on the market. Creaform’s robotic mounted optical system is MetraScan which are 3D scanners that have been seamlessly integrated into automobile and other manufacturing assembly line operations.”

Additec — one of the many companies present at this year’s show

Technical Editor Tsion Asmamaw had this to say about the show: “Proto Labs was the company to visit at the show. This company provides injection molding, CNC machining, and 3D printing for customers who wish to budget themselves conservatively. They can see the proto type design before going ahead with any production or large scale manufacturing. I think the flexibility of this company will quickly create a good stream of customers exploring their vision in no time.”

Asmamaw also pointed out that GoEngineering wasn’t the only company sponsoring Stratasys products: “The second company I was interested in was PurplePlatypus. They displayed the impressive machines from Stratasys. The preciseness of the prints displayed at the booth were handheld examples of accuracy. One example was a human hand displayed with all the blood vessels in true color — all done with injection polyjetting by these incredible machines — the level of detail and realism can only help the medical education industry beyond measure.”

Airwolf3D also presented at the show and, as has been written previously, is a company worthy of taking into space. Their Axiom made a hit with engineers, who although celebrated in their mechanics, have yet to experience 3D printing. Credit goes to Airwolf3D for speaking to this awe-inspiring level of genius it takes to do rocket science. This company is closer than most to being in space. That’s all I go to say.

Lastly, I want to bring your attention to a company that, by all aspects, is not 3D printing related. It is my hope 3D printing companies will seize upon this aspect of technological innovation to improve their products at exponential rate. That company is called Splunk>.

Devon Bolton, account manager for aerospace & defense for Splunk>

Splunk> does data-mining and analytical feedback on levels that make one ponder what cannot be done. Their team has grown steadily in their application of brilliance in what they are achieving. Keep in mind, this is SpaceTech Expo. This is NASA-grade data-mining analysis. Talking to the team at Splunk> is like trying to have a conversation with a genius cousin on scholarship to MIT. These guys see data in ways that make the notion of cosmic-shift likely. Their story on developing better subway braking systems makes me proud to have met them. Remember you heard of them here first.

Plan now for next year’s SpaceTech. Make a family trip of it and develop a love of science in even the youngest of keen investors.

3DCopySystems Launches Scanning Booths in Three Sizes

3DCopySystems co-founders Andreas Schwirtz and Christof Kirschner have been developing advanced photogrammetry scanning technology to provide three new photoscanning booths to completely capture live subjects in fractions of a second. The company hopes the scanning booths, named Big Alice, Little Alice and Alice on the Road, will give them the leading edge in live-object capture. The largest booth, with 64 DSLR cameras, measures approximately 18 ft by 12 ft by 7.5 ft in order to provide with a wide range of object freedom in movement and pose.
