LET'S TALK ABOUT 3D SCANNING

Reverse Engineering a Jeep Wrangler 2005 Auxiliary Light Bracket Mount with 3D Scanning

7/23/2024

0 Comments

 
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.  
Picture
The steps that were taken from editing the scan files to  print:
  1. The scan was imported into CAD software as points and surfaces
  2. Measurements were collected and construction geometry such as planes, contours, etc. were extracted from the scan data
  3. The bracket was modeled from this reference geometry generated by the scanned data
  4. That design was then "optimized" for additive manufacturing, removing as much material as possible, adding lattices
  5. The optimized design was exported from CAD as an STL file
  6. The STL file was sliced in Netfabb using the latest EBPA
  7. The SLM 125 (for AlSi10Mg) and SLM 280 (for 316L) were prepared and the prints launched
  8. The builds were removed from the machine, cut off of the build plate, and sonicated
  9. Supports were removed by hand

Some of the challenges Marlon faced specifically for optimizing for additive manufacturing:
  • Required other software beyond just the CAD software. Other software, such as nTopology, simplifies modeling more organic shapes conducive to additive manufacturing
  • Limited information about the end use of the bracket (how much it was going to support, environmental conditions, etc thus had to make assumptions

Things specifically engineered to optimize for 3D printing:
  • Material removal for light weighting
  • Lattices for additional stiffness
  • Kept overhangs to 45 degrees to minimize support and post-processing
  • Made assumptions regarding loading and boundary conditions

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.

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!

Ditch the calipers and use a 3D scanner for reverse engineering!

2/8/2023

0 Comments

 
Edward Van Zyl, a seasoned 3D scanning and printing expert from Manitoba, heads the company Dreamworks 3D Printing and Scanning. With extensive expertise in vintage car restoration and customization, he is enthusiastic about utilizing state-of-the-art equipment to capture intricate details of automotive components and then utilizing software to generate accurate 3D models. This article, courtesy of Shining 3D, deep dives into the tips utilized by Edward for scanning with the EinScan HX Hybrid Light Source Handheld 3D Scanner and the reverse engineering of car parts through the use of Geomagic Essentials and Fusion 360.

Scanning And Printing An Arrow 50 Scooter Part

Edward embarked on a projet to 3D scan and reverse engineer an Arrow 50 scooter part and then 3D print. He chose the EinScan HX Hybrid Light Source Handheld 3D Scanner for this reverse engineering project.

In the 3D scanning process, Edward provides a small tip: utilizing miniature pyramids as markers rather than some of the markers that need to be put directly onto the object. This has the advantage of saving time and cost, as it eliminates the need for post-scan cleaning and the small pyramids can be reused. You may download files of pyramids here.

In laser scan mode, EinScan HX has a maximum scan speed of 480,000points/s. It just took around 12 minutes to complete the whole scan of the component. And the laser scan mode of EinScan HX makes the scanned data accurate up to 0.04mm, thus you get a very accurate model for subsequent work.

Cutting A Fender Using Geomagic Essentials

Edward’s goal was to cut a fender and make sure it was the right size for installation. Usually, he will print out the part for test, and in this case he offers an easy-to-print and material-saving trick.

​He creates a small offset about 5 mm or even less, and cuts the part again, so that he gets a tiny piece of the fender, but maintains the geometry he need. 3D printing this thin piece was just as good for installation testing, and using only a minimal amount of printed material.

Reverse Engineering An Engine Using Geomagic Essentials And Fusion 360

Furthermore, Edward uses Geomagic Essentials to extract features on the engine, and then using Fusion 360 to model the three holes in which he wants to simulate the mounting bolts.
Picture

One thing to keep in mind here is that you need to maintain the mesh and the extracted features in uniform coordinates. This step ensures that the extracted features can be overlayed on the mesh in the right position. After extruding two cylinders of different sizes and modeling some threads, the mounting bolt is done.
Picture

This is basically how to go from scanning to printing of a part; how to use a mesh and model mounting bolts in Geomagic Essentials and Fusion 360. And it is clear how much can be done with a bundle of 3D scanners and softwares.

Reverse Engineering the 1973 Mini Cooper steering column cover parts with EinScan Pro 2X

4/21/2022

0 Comments

 
Challenge: Finding replacement parts for a classic car
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.
Picture
The 1973 Mini Cooper
Solution: EinScan Pro 2X fills the gap
​John, also being a talented engineer and with his deep knowledge of 3D printing technology, he decided to reverse engineer these Mini Cooper steering column covers and 3D print new replacement parts. Rather than measuring the parts with a caliper and designing in CAD from scratch, John decided to 3D scan the plastic steering column covers to generate a 3D digital surface model to get accurate measurements of the parts with the EinScan Pro 2X 3D scanner​
Picture
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.
Picture
Picture
​ 
The EinScan Pro 2X 3D scanner with the Industrial Kit enabled John to put the object on the turntable and within an hour or so, get a workable 3D mesh. Multiple scans were automatically fused together to create a watertight 360-degree digital surface mesh that was then imported into the Solid Edge Shining 3D Edition reverse engineering software. The surface mesh files were leveraged to build a solid model, make design improvements, and then be further process for 3D printing.
Results: Capturing details enabled precise CAD file creation for 3D printing 
​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.
Picture
“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.​

Also importatnt to note is to understand copyright laws in the US.  Reverse engineering is legal but if you are going to reproduce and profit, you should get in touch with a patent lawyer. With an old part like above, it's beyond the copyright

EinScan 3D Scanner File Types 101

3/15/2022

0 Comments

 
3D scanner is a data-acquiring device that captures the surface model of a physical object in a digital polygonal model. The types of output data format that 3D scanners can generate maybe confusing. What is an ASC file? Which export formats does my CAD software import for rapid prototyping? What is the best practice for saving scans? Which file format is the best choice for 3D printing?  In this post, we will discuss all file types that involve Einscan software.

The type of file you require depends on what you are going to do after the scanning process. There are a total of 6 types of output data formats (ASC, p3, STL, PLY, OBJ, 3MF) that you can export from EinScan software during data capture and generating mesh which are polygon models. We will explain the differences among these 6 file types in this blog.

Point Cloud Data Format

When you have finished your scan and are ready to convert your raw scan data to point cloud data, you can click on the save button to save the point cloud data as an ASC file and the marker position as p3 format when markers are detected.

ASC file contains the position information of each point in the point cloud. This file type can be opened in most scan data processing software and metrology software like Meshmixer, GOM Inspect, and Geomagic Essentials.

The P3 file is for marker reuse purposes in EinScan software. For a large object scan, the user can scan all markers only first and save the marker frame as a p3 file. Later the object can be scanned part by part in a separate project using the same p3 file as a reference which improves the accuracy and will require no alignment between each project.
Picture
With Fix scan mode number of scans will be saved as separate files, while for handheld scans the full point cloud will be saved as one file.

Meshed Data File Format

After the data is meshed, more saving options will be available. ASC file is still available while the mesh can be saved as STL, PLY, OBJ, or 3MF files.

STL file format is the most common mesh file format. It only contains the position and normal directions of all triangles in the mesh. This polygon file format can be opened by mesh editing software and many CAD software like Solid Edge or Solidworks for reverse engineering.

PLY and OBJ file formats contain mesh texture information, including color information, in addition to the STL file. Users can export these data types for digital documentation and online model display.

3MF file is the 3D printing format published by the 3MF Consortium. This format includes information about materials, colors, and other information that cannot be represented in the STL format. Windows system and other CAD software packages can open this mesh format.
Picture
Post Processing Data
​

EinScan software provides basic functions for mesh editing in Post Processing and Measurement sections. Usually, users use these functions right after meshing data. However, external mesh data can also be imported into the EinScan software for editing. The EinScan software supports STL, OBJ, and PLY formats for post-processing and measurement.
Picture
Saving Data in Project Group

The 3D scan data in the EinScan software are saved for later use in a two-layer structure. When the user starts a new scan,  a new project group is created. All the associated files in the project group will be saved as a project under a folder named by the project group.
Picture
The project group folder contains different kinds of files. The project group directory links all projects in the group. The project directory links all data files belonging to this project and the rest are project data files. When moving the project group, the user needs to move all the folders in the project group. 

When opening the project, the user needs to locate the folder where the project group was saved and open the corresponding directory files.The project group folder contains different file formats. The project group directory links all projects in the group. The project directory links all data files belonging to this project and the rest are project data files. When moving the project group, the user needs to move all the folders in the project group. 

When opening the project, the user must locate the folder where the project group was saved and open the corresponding directory files.
Picture
Picture
So that's it!  You have 6 output formats to choose from and all the required scans for your saved project will be in a project group folder.  Remember, the file size for each project is large, so make sure you secure a space on your PC where you can save the files.

3D Printed Valves. Photo courtesy of dezeen.
Recently the media picked up a story about how 3D printing saved the day to produce valves for an intensive care unit in Italy to treat COVID-19 patients.  The Italian startup company reverse engineered, and 3D printed these valves that are key components of Venturi oxygen masks that are connected to ventilators.  

When you read the details however, you realize they jumped various legal hurdles to do this - the valve is protected by copyright and patents with its blueprint not released but in an emergency case such as this one, the hospital seemed to have allowed them to reverse engineer the valve and 3D print them.  The CEO of the company that 3D printed the valves is now is explaining what his intentions were on his Facebook post and LinkedIn video (in Italian).

When emergencies of such enormous scale occur as is happening right in front of our eyes, you just want to help if you have the capability and technology to solve the problem quickly. But regulations exist to ensure safety and durability thus everybody in the 3D printing industry is doing a thoughtful balancing act. 

It is not clear if they used a 3D scanner or just used calipers to do the reverse engineering but 3D scanners can play a key role in enabling accurate and quick reverse engineering of physical objects.

Using 3D scanning technology, you can capture the surface dimensions of complex physical objects accurately and quickly especially with the structured light 3D scanners, then then reverse engineer with various CAD software such as Geomagic and Solid Edge which comes bundled with EinScan Pro 2X & 2X Plus to create a blueprint that can be 3D printed. 

Have a look at how you can reverse engineer products that are missing a blueprint by using 3D scanners.

Happy Halloween!

10/29/2018

What does Growshapes do to prepare for Halloween?  We 3D scan pumpkins!

We 3D scanned this pumpkin using the HP 3D Structured Light Scanner Pro S3 with dual camera and automated turntable.

Actually the pumpkin's organic shapes is more difficult to 3D scan than you think due to the top half and bottom half of the pumpkin being sort of symmetrical.

If you 3D scan the top half first, then 3D scan the bottom half next, alignment can go haywire. There is a high chance that the 3D scans of the bottom half of the pumpkin tries to align to the top half of the pumpkin by the contours of the pumpkin. This tends to result in the bottom half of the pumpkin aligning directly on top of the top half of the pumpkin, ending up with a 3D scan of a half empty pumpkin that is distorted, rather than a full pumpkin where the top half and the bottom half are aligned as it should be.

In order to avoid this, putting some markers on the pumpkin helps.  The markers help the HP 3D Scan Pro 5 software to align the 3D scans to distinct features i.e. markers on the pumpkin, rather than just the contours of the pumpkin as it is flipped over.
In this case we put 2 markers on the pumpkin like this. It doesn't have to be this kind of marker, it can be just some masking tape as well.

If you prepare the object correctly, you can scan objects in a couple of minutes and it will align beautifully.
