- 3D Scanning - is the process of analyzing a real-world object or environment to collect data on its shape and sometimes its appearance, like the color and texture of the object. The collected data can then be used to construct digital 3D models.
At Vision Miner, we use and sell a full line of 3D scanners -- check out visionminer.com/einscan to see all those. Right now, though, I’m going to talk about the different types of 3D scanning, so you can get an idea of what’s out there.
So, first, let’s talk about the different types of scanning technology.
3D scanning actually comes in many forms, some you might already be familiar with. CAT scans create 3D models of the insides of the human body and your modern smartphone sitting in your pocket right now 3D scans your face to unlock it.
Professional 3D scanners however can use a variety of different technologies, each with their own pros and cons. These can easily be split into two categories: contact and non contact. For this video, we’ll focus on the latter of the two.
Contact scanning technologies like CMM or coordinate measuring machines basically take a very sensitive probe and run it across the surface of an object, recording data and comparing it to its digital cad model. Pretty much anywhere where accuracy down to the smallest measurement is of utmost importance, you can find CMM machines.
Non-contact scanning technologies like these four from Shining 3D, use a variety of technologies to capture their data.
ToF or Time of Flight -- this uses a laser light to probe the subject of the scan. A laser rangefinder gets the distance of a surface by timing the round-trip speed of a pulse of light. This is usually great for large scale objects, entire rooms, or even entire buildings. Unfortunately, like the iphone, they’re not super accurate with details, and the resolution of the scans don’t get close to the next types of scanners.
Hand Held Lasers - these use triangulation with an actual laser and multiple sensors, and of the lineup that we have here, this is the EinScan HX -- you can get details down to 0.05mm or 50 microns. Another benefit is that it works with dark and reflective objects, unlike the next technology.
Structured and Modulated light. Most 3D Scanners use this technology -- it projects structures of light (think QR code patterns) as well as modulating bars of light that change back and forth. It then reads this data and calculates the shape and size of the part using algorithms.
Lastly, we have Photogrammetry - this basically takes many photographs from different angles, calculates all the differences, and chunks out a solid 3D model -- however, a big disadvantage of this is that it’s not measuring while it’s scanning, unlike all the other methods -- but it can work great, especially on a budget, and depending on your photographs and style of photography, it can also be very accurate.
At Vision Miner, we specialize in Functional 3D printing, especially high-performance plastics like PEEK, ULTEM, PPSU, PPS, CFPA, and more. We also have extensive experience with 3D scanners, and a whole array of solutions available for purchase. If you're interested in using functional 3D printing and materials in your business, feel free to reach out, and we can help you make the right choice for your application.

I think 3d scanning, photogrammetry, LIDAR, is some of the most awesome advancements lately. We've been finding useful ways to utilize this technology. It's awesome
I love all these videos on 3D Scanning. All of them have touched on a different facet of being able to use these products well to the point that now I feel if I had one of those EinScan HX in my hand I could scan almost anything and be printing it that same week if not the same day. Maybe a couple more advancements and/or lowering in pricing and I know I will have one of these and my own business making people's dreams into realities. Just got my upgrades for my Ender 5 Plus so I can now have the opportunity to print with all materials. About to buy my first roll of CF Nylon and a CF Build Plate from you guys this Christmas; then some PEEK the following summer.
Best explanation as always
Great video,, when I started to scan I thought my business was going toward engineering was I surprised when now I am doing more of the sci-fi side of things.
Thanks again for the video!
That was really helpful and well done. Thank You.
Glad it was helpful!
Machinist here looking at producing billet engine blocks and other components on a cnc machine. What accuracy scanner do you recommend? Obviously the products will be tight tolerances (0.01mm at some points) How much can software make up for a less accurate scan?
We have a HandySCAN Black Elite at work and I am trying to learn how to use it on my own. There is no one there to show me how to use it. Is there a video that shows the basics of VXelements software?
Holyshit ! This guys telling 1000 of getting richs by using 3D Scanning ! Amazing guys ! 😂😂😂 Hand down ! Thank you, you are even better than professor in university
I have a BLK360 and am trying to figure out what industry to start working for laser scanning. Any recommendations on where I can start?
How long do you think it will be before 3D Scanning -- or any kind of visual feedback -- can be used as a basis for 3D Printing? I mean direct measurement of the printing rather than XYZ coordinates. As in the same way a person would craft / sculpt something. Might make an interesting video ;-)
Great explanation, I'd like to see a geomagic essentials video
We just filmed FIVE new videos on Geomagic specifically, should be coming soon, thank you for the comment!

I am a middle age man that desperately wants to learn to use CAD. I've watched TH-cam videos on it, but it feels very strange to me. Are there any resources you would suggest to help a newbie learn this so i can take my furniture company to a new level?
Start with the free tutorials on basic functions, and then it's all about practice, practice, practice :) There are different youtube channels, and some sites like Udemy or Skillshare where you can take courses, but like most things, I'd say the most important thing is to log hours using it. Fusion 360 with the free license is a great place to start!
I will say, most 3d Autocad software is pretty similar in function in most circumstances. If you're using cnc machines, higher end software (like solid edge) can actually stimulate tool paths and even export direct code in certain circumstances, giving you the ability to check your parts for manufacturer ability. It also has FEA and other higher end features of needed.
Mega dittos to Lefteris.
i seen xbox parts used years ago and no or not many good and cheap solutions yet that why my saying cheap as the hardware ant that pricey any more it`s just does it work well yet .but i may wrong ill look into it again
Hi! My name is mehfooz. I am from india. i am working as a cad designer in mould industry. I want to start 3d scanning service. I am saving money to buy 3d scanner to scan plastic product for mould design.. Suggest me a good budget scanner. Which can scan small as well as big parts, From 1mm up to 1000mm size parts. I hope yu will reply...
On a budget, the Einstar could get you started, but I'd really try to get something like the HX with higher accuracy and lasers for scanning many types of surfaces :)
@@VisionMiner what about transcan c?. What will be the price?
Hello Rob, I'm working on a project where scanning is required of people and larger items and could use your help. The project would reach well over 34k prospective subscribers and several hundreds of prospective customers if you are interested. Jeff. P.S. the project is going to help @risk kids, veterans, animals, and others.
Annnnnnnd we LOVE IT! The Einscan H is probably the best option, based off your description. Reach out to contact@visionminer.com and we'll see how we can help!
@@VisionMiner we will want to 3d print them on a 3d systems 660 or possible thr new full color 3d printer by HP
