3D Imagery Preserves Art Treasures

3d scanning Nofretete3D scanning is expected to preserve art for the ages. For instance, the Bust of Nefertiti can take a ride on a conveyer belt so it can be thoroughly scanned and a copy saved that will stand the test of time. The idea behind the 3D scanning of art is to preserve the outer shape of art digitally. That way if disaster or war destroyed the original, the last resort of making a replica of the original could be achieved.

Nefertiti already went through this process. The scanner that is used to perform this feat, if regularly produced, could become a valuable tool in making copies of original art quickly. This can eliminate the need to use plaster casts to replicate sculptures.

Preserving The Past

There are some countries that have had issues with preserving their pasts. Germany is one of those, although they have preserved a lot. Unfortunately, they’ve had setbacks. For instance, the City of Weimar’s library was damaged by fire a decade ago and 50,000 books from the 17th and 18th centuries were ruined. This has resulted in the value of digital copies being recognized.

3D scanning has also been cited as a way to make replicas that can be loaned easily. Some museums even have artifacts that they do not make seen by the public. By replicating them, they can make the treasures seen. On average a valuable museum artifact is only displayed every 10 to 15 years. Three-dimensional replication may result in more frequent displays of rare artifacts.

The Darmstadt Scanner

The Darmstadt scanner, used to scan Nefertiti, is in Germany. The Bust of Nefertiti took a while, but any similar object would also take quite some time. While there are other ways to perform 3D scanning, the Darmstadt researchers say that their scanner is faster because a regular machine can take up to 24 hours to scan a part of the whole.

There are a lot of moving parts to this machine. The object is placed on a conveyer belt that pushes it between two semi-circular gantries. There are nine light sources inside the inner arch and nine outside. The arches move over the bust and the cameras take pictures so the geometric reconstruction can be calculated. From here, an image is produced. A robotic arm with a second scanner then fills in the gaps of the 3D model to complete the digital picture. Although a lengthy process, this may revolutionize art preservation.

Art and Science of Car Design Merged by 3D Scanning

3D scanning is an advanced measuring technology that is frequently used for the reproduction and restoration of fine art. Now it has helped Cadillac, create a concept car that can be considered a “work of art.”

Elmiraj_Concept_car_and_3D_Scanning

The Elmiraj concept car appeared at the Los Angeles International Auto Show until December 1, 2013. 3D scanning played an important role in the creation of this concept car.

An update to the classic two-door grand coupe, the Elmiraj was created through the extensive use of digital mapping technology. 3D scanning was used as the bridge between digital modeling teams that utilize math and hand-sculpting teams who work in clay modeling. The clay model was scanned with precision and speed, and then it was converted into data that was interpreted by the digital modeling team so that the specifications of the design could be created and duplicated.

Basically, the way it works is this: projected light patterns are used by the scanner and an advanced camera captures the 3D shapes so they can be translated into math data. This math data is then manipulated into digital modeling programs that are used to make full-size models.

This is an example of how 3-dimensional scanning has played an important role in car design. It usually starts with a 2D image that is turned into a 3D mathematical rendering. These math models are the basis for the clay hand modeling and the milling that is controlled by computer. The 3D images then allow for reverse engineering and the master math model is updated. Any changes that are made to the math model are then updated in the physical model through milling the clay.

GM is a company that has been notorious for using this technology. In fact, they have been doing so since 2001. They are able to record every change in design with extreme accuracy. A single scan can reveal when there is a need to take a step back and fix something that may be wrong. This allows the car manufacturers to work faster and achieve perfection much easier.

GM alone executes thousands upon thousands of scans annually to troubleshoot part irregularities and to achieve competitive benchmarking.

Overall, 3D scanning enables car manufactures to translate surface from a scale model so a full0size model can be created. Because of this digital mapping technology, this is a process that is completed in less than a week. For Cadillac, it helped create a beautiful concept car.

3D Scanning Gives Archaeology a New Twist

topcon-3d-scanningFor the better part of the past century, archaeologists have studied ruins, artifacts, and statutes. While archaeology has existed for hundreds of years as a way in which people learn about the past, modern times and technology has brought about an increased interest. Along with it comes a history of how archaeologists would record their finds.

Before cameras, archaeologists would sketch what they found. Unfortunately, important details could be missed. After the camera was invented, archaeologists would take pictures and, once again, details could be missed. Now, artifacts can be recorded through 3D scanning and duplicated using a 3D printer.

What the 3D scanner has done for archaeology is solve a problem that has plagued archaeologists for quite some time and that is the fact that 2D images can be difficult to decipher. However, scanning them in 3D and reproducing them that way preserves them forever. Even as the environment takes its toll on the actual artifacts, the 3D reproductions can be preserved through rapid prototyping.

The Scanning Process

To scan an artifact, the scanner is set up near the artifact within 3D scanning range. The scanner can scan the smallest details in excellent resolution so that the smallest of details can be recorded. Fortunately, 3D scanners are easy to transport because they are lightweight and simple to set up.

Once the scanner scans the artifact, the image is saved in IGEs, OBJ, STL, VRML, or another desired format. There are a number of 3D viewers on the market that enable a person to download the data and scale, measure, and analyze the intricate details of the artifact. This saves a lot of money and time for archaeologists because they can take the data from a 3D scanned artifact and study it in the comfort of their home or office. They can view every detail as if the artifact is in front of them. This is enabling 3D scans to be used in classroom environments so that students are able to acquire more information about specific archaeological finds.

Conclusion

Since the first artifact was scanned in the field, it has been found that 3D scanning can be used to preserve statues, artifacts, carvings, and similar finds. Because of the ease of use, portability, and the accuracy when capturing data in challenging environments, 3D scanning has become a preservation method, a teaching tool, and a way in which archaeology has been revolutionized.

Jay Leno’s Garage Uses 3D Printing Tech to Recreate Classic Car Parts

Jey-Leno-3D-printing3D printing technology has taken the world by storm, taking two dimensional images and printing them in three dimensional form. In Jay Leno’s garage, he uses 3D printers to recreate classic car parts that have gotten rusty over time. Many of the parts are no longer made or difficult to have made, so he turned to 3D technology to recreate and replace them.

All he needs is a 3D scanner and printer. The process is one that is more convenient and affordable than finding a machinist who can copy and rebuild. Even if a machinist builds the part wrong, it still has to be paid for.

The Process

The scanner first scans the part at 50,000 points per second. The density is 160,000 dpi, which then creates a detailed digital model. Defects in the part may be included, but those defects can be removed by software. The 3D printer then creates a plastic replica, which is sent out so a mold can be created.

In some cases, the printer can create a replacement part in cobalt chrome. This is done using what is called the “direct laser sintering process.”

During the 3D printing process, the printer head moves back and forth, placing layers of plastic on top of one another. It is not out of the ordinary for a 3D part to take over 24 hours to complete, but the system creates the perfect part. Rather than receive a fabricated part and it not fit, 3D printing makes securing the perfect fit much easier. The machinist simply replicates the part in metal. Leno can input the data into a Fadal CNC machine to create a metal replica of the plastic part.

Putting Old Cars on the Road

Leno’s 1907 White Engine is a success story because it would have most likely never run again without this technology. It had a shot slide valve. Because they were able to duplicate the part and have it built, the car is running. This isn’t the only success story in his garage.

While 3D printers are not cheap, the prices are expected to come down over time. There are different price points based on the capabilities of the printer. The printer that Jay Leno uses costs upward of $15,000, but 3D printing is saving him more than that on replacement car parts for his classic cars. This could mark the beginning of a new era for mechanics.

GM Finds Out Competitor Car Details with 3D Scanning

GM-3D-scanning-serviceGM has been working hard to close the competitive gap between them and other car manufacturers, which is why it has turned to 3D scanning of competitor vehicles so they can learn as much about the automobiles as possible. They want to know what makes a Mercedes what it is or what makes a Chrysler what it is. To do this, they run the rival designs through computers and they analyze them.

What is surprising is that this is not a practice that GM just started doing. In fact, they have performed 3D scanning of competitor models for over 10 years. What the practice does is turn 3D objects (cars, trucks, and SUVs) into data on a computer screen. They don’t always do this for reverse engineering or benchmarking, but to turn a clay model into mathematical data. With the more widespread usage of 3D printing, this mapping of competitor designs could result in the engineers at GM being able to easily and quickly upgrade their vehicles. Continue reading

3D Systems and Lotus F1 Team Up for Mass Production Project

2012 Formula One Barcelona Test Day ThreeRace car enthusiasts ought to get a kick out of the latest news from 3D Systems and the Lotus F1 team. They have partnered up to use 3D printing to create parts for Formula 1 cars, in an effort to streamline aerodynamics and improve production efficiency.

Everything they do is an effort to improve vehicle performance. This is why the Lotus F1 team sought out 3D Systems tech. According to their Head of Aerodynamics, Dirk de Beer, the machine allowed them to create prototypes on the spot that fit the vehicles. While they started out with rapid prototyping, they quickly moved on to wind tunnel model manufacturing. This created new jobs as well, expanding the Aero Department’s team from 11 to 80 employees. By creating prototypes and testing them, the team can make changes and develop new ideas to further progression. The more ideas they can actively test, the better their chances are of succeeding come race time.

The 3D printing tech is actually used in some pretty novel ways. After applying pressure sensors to the car model in the wind tunnel manually, researchers can now place sensors within complex, intricate, and tiny structures that they couldn’t have otherwise gained access to. Everyone in the field of aerodynamics has reason to celebrate because it revolutionizes just what is possible. Continue reading
