Reverse Engineering a Can Holder

By | 2018-06-27T08:39:57+00:00 June 27th, 2018|Categories: 3D Printing / Additive Mfg, 3D Scanning|0 Comments

We reversed Engineered this 6-pack can holder which is great for quickly snapping cans on to it and easily carry them around. Here’s a brief overview of how we reverse engineered it, improved the design, and then optimized it for injection molding. First, we used 3D System’s Capture scanner to scan directly into Geomagic’s Design X. With a resolution of .110 mm, and an accuracy of .060 mm, we were able to capture even the finest details. Since the base geometry is patterned, we just needed to ensure that we capture enough geometry of one can holder and then we used CAD to pattern the other 5 holders. With Geomagic’s Design X we are able to interrogate our scan and trace the outline of each feature that we needed in order to recreate the sketches and features in our CAD file and then check the deviation between our CAD model and the original scan data. When done, we did a “Live Transfer,” meaning we exported the feature tree out to our CAD software. This allowed us to make modifications to the design as if it was natively created in CAD. We were able to leverage this and strengthen the areas [...]

Differences Between Scan-Based and CAD-Based Neutral Files

By | 2018-05-22T16:47:11+00:00 May 23rd, 2018|Categories: 3D Scanning, Tech Tips|0 Comments

Scan-based files involve cleaning up the scan, optimizing the mesh quality, and ensuring that the scanned mesh is watertight. At this point we can generate the neutral file based on this processed scan data. CAD-based is bit more labor intensive. It involves interrogating the mesh, creating CAD sketches and CAD features and fitting them to match the scanned data. Once the scanned data has been recreated as CAD data, we can then generate the neutral file based on the final CAD geometry. Let’s analyze the differences between the two. The main difference between these two approaches is that a CAD-based neutral file is able to preserve the true geometric features of the scanned part. This means that a cylinder would remain a true cylinder. The same would apply for planar faces, cones, and spheres. This would allow you to create and leverage construction geometry, such as planes, axes, and faces. Being a true CAD shape, any sharp edges on the original part would also be preserved. In summary, if you are looking to preserve geometric features, use the file for 2-axis machining on prismatic parts, or plan on modifying a neutral file in CAD, a CAD-based neutral file would be [...]

Geomagic Capture Scanner

By | 2018-05-11T08:30:21+00:00 May 11th, 2018|Categories: 3D Scanning|0 Comments

The Geomagic Capture Scanner is an industrial grade scanner that can be used for both reverse engineering and inspection. It allows you to bring physical parts into CAD for the purpose of reviving a lost design, developing entirely new products, or inspecting existing parts. Let's take a look at some of its key features. The Geomagic Capture is a blue light scanner offering fast and accurate scanning in a portable, lightweight unit. This device can hold accuracies of +/-.0035" and is very simple to set up and use. The Capture scanner connects to the PC through an Ethernet port and the turntable requires a USB connection. All of the Geomagic software products synchronize the turntable with the scanner to register or align adjacent scans, producing perfectly aligned complete mesh models for various downstream applications. The Capture Scanner is a great tool for companies looking to get products to market faster. Let's say you have an older physical part with no design data or drawings. With the Capture, you can acquire the data, process it, and then bring it into CAD in order to make modifications to the original design. You can digitally restore the old physical part, similar to converting [...]

At times, a customer will come to us with an idea whether it is a hand sketch, a picture, or a simple drawing with dimensions on it in hopes of creating a prototype by 3D printing it. Here, at Cimquest, we have all the tools needed to create and produce these ideas and bring them to life. To illustrate this, we have created a portable case to carry a 3D Connexion Wireless Space Mouse and USB, since there was nowhere to place the USB receiver when carrying the mouse around. We still had the molded pulp packaging, which contains the cavity of the space mouse, with a perfect fit, so our first task was to capture this geometry. We used Geomagic's Capture scanner for this task, which scans at a resolution of .007." As it rotates and scans, it aligns each scan to the next and then easily stitches them together as one clean mesh file. Next, we used Design X to reverse engineer the geometry into an editable CAD model. Once we recreated what we needed, we exported out the geometry and the Feature Manager Tree to SOLIDWORKS. In SOLIDWORKS is where the engineering happens. After completing the bottom [...]

Upcoming PMI-Driven Inspection Seminar

By | 2018-02-21T08:30:04+00:00 February 21st, 2018|Categories: 3D Scanning, Events|0 Comments

Join Cimquest for an in-depth look at PMI-driven inspection using CAD (SOLIDWORKS) and Geomagic Control X. In this workshop, you will see the seamless integration of Product Manufacturing Information from CAD driving a complete part inspection in Control X. By setting up PMI dimensions with tolerances, datums, GD&T, notes, labels, etc. in SOLIDWORKS using ‘Dimension Expert’, the inspection of the part then becomes fully automated. Presentation topics include What is Product Manufacturing Information and why is it important to you? How does non-contact inspection work? Eliminating mistakes of interpreting inspection drawings by having the parameters for inspection entered one time in CAD and then automatically read and executed by Control X. EVENT DETAILS Date:  Wed, March 14th Time:  9am-11am & 1pm-3pm Location: Cimquest Inc., Branchburg, NJ Cost: Free Who should attend? Shop owners, Quality Managers, Programmers who also inspect, CAD users whose designs go to machine shops for fabrication, inspectors. To register please click the button below. Register Here

Part Inspection in Batches

By | 2018-01-12T08:29:32+00:00 December 20th, 2017|Categories: 3D Scanning|0 Comments

You can easily perform part inspections in batches and automatically generate inspection reports for each part using a Creaform HandyScan scanner, along with Geomagic Control X software. The first step is to capture your parts’ geometry with a metrology grade, certified scanner. Scan each part in the batch, and export an STL file. It’s handy to put all of the scans in one folder. The next step involves creating a master file that will be used for comparison and inspection. Once you’ve imported the CAD file into Control X, add the appropriate dimensions, tolerances, Datums, and GD&T information to the CAD model. This critical inspection information may also be seamlessly transferred from CAD into Control X. Next, choose the method of alignment for your scan, so that you can align it with the CAD model correctly. Although we typically use the datums called out on the manufacturing drawing, various alignment methods are available depending on the need. Once you have the scan aligned, create the types of analysis that will be performed and orient their corresponding views. Last, you can prepare your report by choosing which information you want to include. You will notice that with little effort, the analysis [...]

Reverse Engineering a BMW Speaker

By | 2017-12-19T09:21:32+00:00 December 6th, 2017|Categories: 3D Printing / Additive Mfg, 3D Scanning|0 Comments

Reverse Engineering has many purposes, one of them being to recreate parts or components that are no longer manufactured. With straight-forward mechanical components, this can be accomplished with a variety of measuring instruments. This task can quickly become more complex though, if the part takes on more of a freeform or ergonomic shape. To serve as an example, the president of our company recently had one of his speaker covers broken. Despite the fact that this is something that can be purchased, we decided to reverse engineer it with all the available tools here at Cimquest. The first step was to scan the part and capture as much as the geometry as possible. This was done with the Creaform HandyScan 700 scanner, which has a resolution of .2 millimeters. Next, we imported the scan into Geomagic Design X. This software allows us to interrogate our scan, and trace the outline of each feature that we need in order to recreate our CAD file. When we’re done, we end up with a fully-featured, editable CAD file that can be exported into a variety of CAD packages. In CAD, you are able leverage these fully editable features to make modifications and optimize [...]

Reverse Engineering a 3D Pipe

By | 2017-12-21T09:14:21+00:00 September 20th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

This blog article will illustrate how to extract the centerline of a 3D pipe with compound angles. Extracting the centerline of a 3D pipe that contains angles in 2 dimensions is not that complicated. However, when you have compound angles, and the tube is bending in the X, Y, and Z directions simultaneously, extracting the centerline can be quite challenging. For example, below we have a prototype of ½ of a bicycle handle, printed on the HP Printer, in Nylon 12. It contains bends in compound angles. Let’s say you don’t have the CAD file to work with and would like to extract the centerline, so that you can create a true CAD file, improve it, and then eventually create a manufacturing drawing . . . One solution to accomplish this is to use Geomagic Design X software and this is how it would work. First, you would need to capture the physical geometry of the handle bar using a 3D scanner and then export an STL file. Next, import the STL file into Geomagic Design X. Design X has a function called: Sweep Wizard. With a few clicks, it produces a fully editable feature tree to create this shape. [...]
