Most companies that have a need to digitize parts ask the “Make/Buy” question. Do I purchase part scanning equipment and train staff (Make) or do I find a good service provider (Buy)? Or are there levels in between this?
About Rob Glassburn
I am a registered Professional Engineer and Vice President of Operations at 3D Engineering Solutions in Cincinnati, Ohio. I’ve spent my whole career in the engineering world and attained certifications in Tolerance Stacks and GD&T, and Six Sigma Green Belt (DFSS and DMAIC). I hold the following degrees: BSME, MSME and MBA
Before joining 3D Engineering Solutions, I worked for Texas Instruments and 3M. Currently at 3D Engineering, a lot of the projects I’m working on involve industrial CT scanning, 3D laser scanning, structured light scanning, reverse engineering, CAD modeling and long range laser scanning.

We have all seen prints with many datum reference frames on them. The fact that there are multiple sets of datum’s is not an issue and is put in place for functional design reasons. There can be so many that they look like an alphabet soup. But what about raw castings? Generally the functional part […]
A common question that we are asked is: what is the resolution of a CT scan for determining gaps or voids or true surface locations? We are also asked: How can you measure a gap between two parts that may be closer than 1 voxel in size? The answer lies in sub-voxel surface determination and […]
Modern Additive Manufacturing (AM) methods often employ subtractive machining to achieve precise dimensional and surface finish characteristics. This is due to current AM limitations in build precision and surface quality. These hybrid AM / subtractive components also demand a hybrid approach to measurement. Internal features on AM parts are difficult or impossible to non-destructively measure […]
COVID 19 has literally shut down a majority of the world’s production. As we have talked with our customers over this time, we have found that many have reduced their workforce or have implemented rolling furloughs. The problem is that once you let that skilled person go, they may actually find other work before you […]
First Article Inspections (FAI) are used to ensure that parts off of new or modified tooling or processes conform to the part design requirements. This even includes changing the location of manufacture! Yes – this can make a difference sometimes (usually due to different equipment, the same equipment setup slightly differently, environmental conditions, different manufacturing […]
Your Molds and Dies are critical to your business. They were meticulously created and iteratively tuned until the parts they produce are within specification. At that point, they were put into production and no documentation of the final tuned geometry was captured. This is actually the standard operating procedure for most of the world. The […]
Many measurement and reverse engineering requirements require more than simple caliper or micrometer measurements. Whether you are conducting a First Article Inspection (FAI), troubleshooting a manufacturing issue or reverse engineering a legacy part for improvements, one or multiple of the modern data collection methods may work – but what is best and what are you […]
Contact measurement devices constitute the majority of what is traditionally used for dimensional metrology. These consist of devices that must be in physical contact with the object to be measured. Below is a listing of general types of contact measurement devices. This covers the vast majority of what is used today and is a good […]
Non-contact or touchless dimensional measurement devices are the modern new comer to an array of contact devices that have been traditionally used. Contact devices are discussed in this link on Common Contact Measurement Devices. All of the non-contact devices generate a point cloud or voxel data set as their most raw form of data. The […]
