Manufacturing Case Study: From 3D Scanning to CAD

Posted By Thomas Tong on February 19, 2013 at 11:00 AM

This week’s blog post is contributed by 3D3 Solutions’ distributor in India, Aman Bir Singh, from Rasco Automotive Systems Private Limited

Designers need an efficient workflow to convert their design prototype into a mold for mass production. Rasco Automotive Systems recently collaborated with a commercial automotive manufacturer to achieve this goal using a process called Scan to CAD.

In this project, the design prototype is a seat that was designed by hand. The Scan to CAD process involves using a 3D scanner to capture digital 3D scans of the prototype. The 3D scans have the prototype measurements which are used to create a Computer-Aided Design (CAD) model. The CAD model is then used to create a mold of the prototype for final production. In this project, Rasco Automotive Systems scanned the prototype using the HDI Advance R1 scanning system.

In this project, Rasco Automotive Systems encountered three challenges they were able to solve successfully:

Tips for 3D Face Scanning with Hair

Posted By Pauline Tang on February 13, 2013 at 11:00 AM

In the past, capturing hair was an exercise in futility. For a head scan, the facial features would look great, but the person's hair would barely be visible or it would not show up at all. Scanning hair can be a challenge for many types of 3D scanners including structured-light systems. Hair consists of very fine and partially translucent filaments which scatter the light and are often interpreted as noise during 3D reconstruction. As a result, these areas are usually removed from typical scan data. With the release of the latest version of FlexScan3D software (version 3.1.7) that powers the HDI 3D Scanners, we introduced a new High Sensitivity mode to address this shortcoming.

This article provides an overview on acquiring usable hair scans specifically for FlexScan3D. While it is mainly targeted at scanning human hair, it also applies to scanning other objects, such as fuzzy clothing, stuffed animals, or dense vegetation.

3D Scanning Technology Trends for 2013

Posted By Pauline Tang on January 28, 2013 at 1:30 PM

As we welcome the start of 2013, here are some 3D scanning technology trends we saw in 2012 that will continue into the 2013 year.

Structured-Light Based 3D Scanning Technology is Gaining in Popularity

In the past, a majority of the 3D scanners in the market uses laser dot or laser line technology. As structured-light 3D scanning technology started to emerge, there wasn't a lot of customer product knowledge surrounding the differences between a laser 3D scanner versus a structured-light 3D scanner. Today, almost half of the products now being introduced are based on different forms of structured light technology. With options at the high end, mobile and entry level market, full-field structured light scanning is seeing more market adoption.

Innovative Applications for Low Cost 3D Scanning Using KScan3D

Posted By Pauline Tang on January 7, 2013 at 12:00 PM

With the launch of KScan3D in August, there is a low cost option for people to create innovative 3D scanning projects as the technology becomes more affordable. With KScan3D, Kinect hardware, and a PC or Mac running Windows OS, users can capture 3D scans with a click of a button. Here are a few KScan3D customers that use the 3D scanning software for innovative applications:

The Process of Creating 3D Sculptures of Pregnant Women by Get Babied

The 3D scanner is built on using multiple Kinects connected to KScan3D software. A pregnant woman can be scanned in 360 degrees using a slowly moving pedestal. Once the data is captured and processed, the information is sent to a 3D printer where a plastic cast is printed of the pregnant belly. Other personalized keepsake such as charms for bracelets and necklaces and ceramic busts can also be created using this technology.

3D Scanning for the Holidays

Posted By Pauline Tang on December 21, 2012 at 4:00 PM

As we approach the end of the year 2012, we want to wish you and your family happy holidays and a great start to the new year in 2013!

In continuation with our holiday festivities from Halloween, we decided to scan a few of our favorite Christmas tree ornaments using the HDI Advance R3 3D Scanner using color cameras and the rotary table system.

Sustainable Archaeology Animation Unit Creates Digital Archives of Archaeological Collections using 3D Scanning

Sustainable Archaeology, and its Sustainable Archaeology Animation Unit (SAAU), has taken innovative steps to make Ontario’s archaeological records accessible to researchers, students, and the public without stepping into a museum or storage facility. Sustainable Archaeology is a research initiative at Western University funded by the Canadian Foundation for Innovation and Ontario Ministry of Research and Innovation. The SAAU, the first animation studio dedicated to archaeology, was established as a joint collaboration between Sustainable Archaeology, the Museum of Ontario Archaeology, and theskonkworks Inc. Its mandate is to combine three-dimensional (3D) artifact digitization and computer generated imagery (CGI) to achieve the long term preservation and digital archiving of Ontario’s archaeological heritage. The Animation Unit received funding from the Ontario Museums Technology Fund and a MITACS Accelerate Internship award.

One of the most important aspects of the SAAU is their commitment to accuracy and completeness when virtually reconstructing archaeological sites and artifacts. Sustainable Archaeology had contacted 3D3 Solutions to propose 3D scanning solutions that would allow for the digitization of large archaeological collections quickly and accurately. The system had to be able to handle large volumes of artifacts that range in different shapes and sizes, as well as encapsulate the true likeness of the artifacts with high resolution color and texture capture.

Presentation on The Fundamentals of the Structured Light 3D Scanning Process

Posted By Pauline Tang on October 2, 2012 at 12:00 PM

Last week, 3D3 Solutions exhibited at TCT Live in Birmingham, UK. We want to thank those who came by our booth. We had a great time meeting other professionals involved in the concept, design, and manufacturing.

On the first day of the conference, our president, Thomas Tong, presented on the topic, 3D Scanning 101: The Fundamentals of the Structured Light 3D Scanning Process. Here are some takeaways from the presentation:

  • 3D scanning is a multi-step process that involves preparation, scanning, and processing of 3D scan data.
  • Good preparation prior to scanning will lessen the work later on in the process. On the other hand, poor preparation will lead to more work later on in the process (especially during post-processing)
  • 3D scanning is a skill that requires trial and error and patience. The more practice you get, the better you will become at 3D scanning.
