THE PROBLEM: The Jeep Wrangler auxiliary light bracket mount had a stress fracture thus needed to be replaced. THE CHALLENGE: Reverse Engineer the Jeep Wrangler auxiliary light bracket mount and make it stronger than the original bracket mount using the latest 3D scanning and 3D printing technologies. 1. Background Chris loves driving around Lake Tahoe in his open-top Jeep Wrangler, enjoying the blue skies and fresh air. The Jeep Wrangler is his vehicle of choice for fun adventures and transporting his wet dog after a swim in the lake. One day, Chris noticed that one of the auxiliary light mount brackets at the front had cracked. Initially, he planned to search for replacement parts, but then he heard about Growshapes' 3D scanning technology. Intrigued by the idea of reverse engineering and 3D printing the bracket, he contacted Growshapes to explore the possibilities. The original bracket mounts were made of plastic and had cracked under stress, so Chris was looking for a solution that would be stronger and more durable than the originals. 2. The Tools and Method Growshapes used Einscan Pro 2X 2020 to 3D scan the cracked plastic bracket mount and worked with an engineer at Uniformity Labs to reverse engineer and create a metal 3D-printed replica. 3. The Reverse Engineering Process Step 1: 3D scan the bracket mount to capture complex geometries using Einscan Pro 2X 2020 Growshapes received the broken plastic bracket mount from Chris. Judging from the size of the part, we decided the best scanning tool was the EinScan Pro 2X 2020 that can capture intricate details with high accuracy, especially in fixed scan mode using it in conjunction with the automated turntable. For small objects, EinScan Pro 2X is the way to go for sure. It captures fine details as point cloud data, then converts it into a mesh that can be exported as an .stl file into a CAD software such as Solidworks. Growshapes 3D scanned the black plastic part that had a fracture on the main wall of the bracket mount. You can see the fracture in the scan results below. We scanned the bracket in fixed mode to digitally capture accurate data of this small part. Fixed scan mode was chosen to use the 3D scanner with the automated turntable. There was no need to put any markers on the parts as the scan was aligned to the markers on the turntable and didn’t even require spraying even though the part was black. The Einscan Pro 2X 2020 uses structured white light technology and the software allows for the capture of dark parts.
Step 2: Reverse Engineering We required expert knowledge rather than simply converting the 3D scan data into a solid model in CAD as the output was going to use additive manufacturing technology, and 3D printed metal. Therefore Growshapes worked with an expert at Uniformity Labs to create the output required. Groweshapes sent the raw scan data in .stl file format to Marlon. Marlon, who led Application Engineering at Uniformity Labs started the reverse engineering process by importing the .stl file of the original design that Growhapes 3D scanned into his CAD software Solidworks. For Marlon, extracting the geometry data from scan data was easier and required less time than measuring the bracket with calipers as it gave accurate values quickly. Furthermore in the CAD software, Marlon was able to model directly over the scan using it as a constant reference. The key expertise Marlon added further was optimizing the design for additive manufacturing in metal, i.e. removing as much material as possible while ensuring strengths which results in adding lattice design. The steps that were taken from editing the scan files to print:
Some of the challenges Marlon faced specifically for optimizing for additive manufacturing:
Things specifically engineered to optimize for 3D printing:
The original bracket was made from injection molded plastic but the plastic gave way to stress over time. The metal bracket should be stronger than the original plastic bracket mounts. Marlon decided to use 316L (stainless steel) as is resistant to corrosion in harsh weather and can withstand varying temperatures. Injection molding requires a substantial investment in tooling thus requires volume production but with additive manufacturing, one-off print is possible with drastically shorter lead times. See the full additive manufacturing workflow below: Chris is happy with the new and improved auxiliary light bracket mount that is stronger than the original one that came with the Jeep Wrangler. He won't have to worry about having another stress fracture in the bracket mount. Reverse Engineering is not just about replicating but also about improving upon the original design!

See the innovators on Growshapes’ social media channels to get the latest expert news on innovation in 3D digitization, then share your thoughts and join the conversation about 3D digital innovation with #digitize3D Every once in a while, it’s important to revisit the basics to understand how 3D scanners work. In this blog post, we’ll cover the Field of View (FOV) of a 3D scanner and how it affects the 3D scan results. The key takeaway is that different 3D scanners have different FOVs, and choosing the right model is crucial to getting the right output depending on the size of the object you want to 3D scan. What is Field of View (FOV)?Like how humans can see a certain range (you can't see behind you) at a given moment, different 3D scanners have a different viewable area at one time from a specific distance. The larger the FOV, the larger area the 3D scanner can 'see' thus capture at once. With the EinScan 3D scammer models, there is a variety of scanning range among different 3D scanner models that scan something as small as a coin to something as large as a car. Therefore, it is important to understand what you are scanning and what FOV is most suitable to capture the details of the object. The FOV of a 3D scanner can determine which model is best suited to 3D scan your object depending on its size. Choosing the right field of view is about finding the right balance between capturing enough detail of the object you want to scan and appropriate coverage for each scan. This balance is important so you can achieve a smoother scanning experience, complete scans in a shorter amount of time as well as reduce computer crashes that happen when the software is overloaded. |
What happens when you use a 3D scanner with a small FOV to scan large objects? When you scan a large object with a 3D scanner optimized for scanning small objects, you will have to do more scans to reconstruct a complete 3D digital model than you would with a scanner with a large FOV. Look at the theoretical diagram on the left. If you have a large FOV, you only need 3 scans but with a small FOV you need 12 scans. In reality there are overlaps so this is just an illustration. |
With EinScan 3D scanners, you can set the resolution you want to 3D scan at depending on your target object. Some key things to remember when selecting the correct resolution are below:

John Buffington is a classic car enthusiast. He loves restoring cars to their original glory and breathing new life into a classical design. He recently noticed that many of the interior plastic parts of his beloved 1973 Mini Cooper was succumbing to the hot temperatures and high UV exposure of the Nevada desert. One of the critical interior pieces that required immediate replacement was the two steering column covers. The covers were dry, brittle and decaying. They needed to be replaced as they were no longer able to be secured together. However, with a rare classic car like this 1973 Mini Cooper, finding replacement parts in the US is extremely difficult and expensive. |
He used the EinScan Pro 2X 3D scanner with the Industrial Kit, which is the tripod and automated turntable accessory that enables higher accuracy scanning in fixed mode. When using the Industrial Kit, the handheld 3D scanner is placed on top of the tripod and converted into a desktop 3D scanner and used in conjunction with the automated turntable. This set up automates the whole 3D scanning process as well and enables a more precise alignment utilizing the markers on the turntable. |
The black steering column plastic parts were covered with AESUB spray to ensure every detail was captured. The AESUB spray lightly coats the object with a thin layer of white powder which evaporates automatically after use without leaving any white residue, making the whole process cleaner. The EinScan Pro 2X captured the dimensions of the object with exceptional precision and accuracy, picking up every minute details, giving John the confidence to reverse engineer the steering column covers. The details of the screw bosses that would have been difficult to measure by calipers were captured by the 3D scanner. The EinScan Pro 3D scanner was simple to use and provided more accuracy than manual measurement. Instead of having to design from scratch, John was able to to create high quality 3D surface mesh files using the 3D scanner. |
By using the EinScan Pro 2X, John was able to capture the surface details of the steering column covers as a mesh file (.stl format) which he then imported into the Solid Edge Shining 3D Edition CAD software in which he converted the .stl file into a .step file with precise details of the fastening features, the alignment pins and screw bosses. Time-consuming, inaccurate, and inconsistent manual measurements are now a thing of the past and with 3D digital technology, reverse engineering a classic car part can be fast and accurate. |
“By using the 3D scanner, I was able to focus on creating the CAD file suitable for 3D printing without having to wrestle with measurements and generating a CAD file from scratch.” - John Buffington.
Structured Light 3D Scanners Structured Light 3D scanners project a light pattterns onto the target object. The changes in the variance in the light patterns are tracked by the cameras and the software algorithm generates point clouds to capture the 3D surface. The structured light pattern projection allows the 3D scanner to captuer a large dimension in seconds in high resolution. Structured light is not hazardous to eyesight. It best performs in an environment where the light condition is stable. There are white light and blue light structured light 3D scanners. Blue light has a narrower wavelength where as white light is a combination of all the colors in the visible spectrum. The narrow wavelength enables better filtering of the interference of ambient light thus offers better precision, accuracy and higher quality outputs. |
Laser 3D Scanners Laser scanner projects a laser point or beams onto the target object and the reflection of the laser light is captured with the sensors. Laser light is less sensitive to environmental light and performs better in capturing shiny or dark surfaces. However, very shiny or transparent surfaces are still difficult to capture by laser light. |
Resolution Resolution defines the point distance of the points within the point cloud the 3D scanner is capturing. The distance between two points in a 3D model is one of the most important factors for your scan. When you take a high resolution, the point distance is very small, and details are better to see on the scan. If you capture in low resolution, the point distance is big and big objects can be captured faster and the 3D scan data file size will be smaller. |

Yukiko’s “Bird” series is something she has created since 2012. Having grown up surrounded by nature, Yukiko wanted to express beautiful organic shapes through ceramics. During the Bon Festival when Yukiko was honoring her grandfather’s spirit, a beautiful bird landed in her garden and befriended her. That was when she decided to create the “Bird”. The series have further evolved to have a more streamlined form after visiting the U.S. and seeing a bird soar in the sky. She felt the wind as she watched the bird fly away and wanted to express it. How beautiful! |
