I have gotten a lot of questions about how well the Miraco can scan detailed parts or be used for reverse engineering. I have to remind you that Revopoint make "hobby" scanners, but they have impressive specs and resolution. I just often see people comparing a hobby scanner to a professional scanner. They are in different ballparks for speed and accuracy.
With that said, the Miraco and the Mini scanners from Revopoint offer up a single frame accuracy claim of 0.01mm. Is it too good to be true? In this video we review 3 different scans and talk about what works and what doesn't.
Turbo - a360.co/3QNhxea
Rim Casting - a360.co/3SPFxjI
Marker Light - a360.co/47lQOwq
The Miraco did great with the rim casting marks and the turbo. It had a little more trouble on the marker light due to multiple pieces, rubber gasket and deep cavities. A lot of scanners struggle here, but in the end we can capture enough details on each object to have something to work with.
What I found through the process was that higher details scans do better with mesh processing(smoothing), while larger scans like car fenders do better with point processing (smoothing). When combining multiple scans together, having clean overlapping sections is a key detail.

I've had the Pop 2 for a while now and even though it does have its quirks, I'm beyond ecstatic to have that level of technology at hand for an unbelievably affordable price. Literally only 5 years ago, Joe Blow hobbyguy owning a 3D scanner like this was unthinkable. Honestly the biggest problem I've seen with these is the customers unrealistic expectation. They think they should just be able to pick it up and immediately get perfect scans without learning how to use it or how it works, and at the same time they expect the performance of a $100,000 Creaform system lol. I would say 99% of the people complaining about accuracy level etc don't even possess the tools or skills to replicate half the accuracy when making a part.

@LearnEverythingAboutDesign 8 месяцев назад

I agree 100%. Pro scanners are faster and more accurate, but what we can do with these tools is amazing. I don't think there is much more benefit coming through on the hardware side of these hobby scanners. The next few years they will need to focus on software improvements.

@Projekt5.3 8 месяцев назад

@@LearnEverythingAboutDesign I definitely agree. Incorporating something like MeshMixer into the software wouod make itmuch more powerful.

I think a lot of people are expecting a magic wand essentially. I've never had any scanned file that I didn't have to do some kind of cleanup work on. Thanks for the video!

@LearnEverythingAboutDesign 7 месяцев назад

@@hillfortherstudios2757 Exactly, and for a fraction of the price too :). I mean sure if you pay 6 figures for a metra scan it better be pretty dang accurate, fast, and easy. but not for $1000

@Projekt5.3 7 месяцев назад

@@hillfortherstudios2757 EXACTLY. I used to work at a BMW production plant in the quality department and I spent some time with the metrology guys and they had a quarter million dollar scanning system and it still had noise and still had trouble scanning dark or reflectice surfaces, but people want to complain that their $700 Chinese scanner doesn't produce perfect models by just waving it around lol

The new creality scanners are really tempting. I probably will buy the creality raptor and the otter looks really good too. It can scan black objects with ease. Blue laser scanning finally affordable. Edit: I bought the Creality Raptor now. I own a Einscan SP, Revopoint mini and Einstar. The problem is I often have to scan parts in the size of a Xbox controller and the parts are 90% black (I have Aesub blue/orange but using it isn’t always easy depending on the part). The Einscan sp can’t handle black well and is stationary. The Einstar is not good at scanning such small parts. The Revopoint mini is only good for very small parts. I hope the Raptor will be the perfect middle ground. Only issue is you need to use markers. I already 3d printed targets and hope this will do. The blue laser should also be able to scan deeper pockets better. At least I hope so 😅

@LearnEverythingAboutDesign Месяц назад

I am working on an Otter video right now. I scanned a white xbox One controller without problem. black anodized triple clamps and a few shiny parts well(there is a limit of course). The Otter is impressive, i think the main issue with Creality scanners(which ill mention in the video and did in the Ferret video) is the software. For your Einscan you have great exscan software. With revopoint and creality the software is really where the difference is. I hope the software gets better for the scan raptor because it would be a shame to have an affordable laser scanner but be throttled by the software. Both the ferret and otter seem to do pretty well with black objects which is surprising. I think the tracking is pretty good as well. I believe it always captures color data which helps, but its marker tracking isn't as good as others. The creality stuff seems to shine scanning those shiny objects(no pun) and outdoors more so than other IR based scanners. The Mini2 scans a little larger size than the mini and has some other upgrades from the mini, but not worth buying if you already have a mini. The Miraco is still my favorite for its portability and the dual depth cameras to do large and small. The otter has a "medium" mode and in the hardware I am not sure exactly what they are doing to get that since it only has 2 sets of depth cameras.....

@Todestelzer Месяц назад

@@LearnEverythingAboutDesign yeah I looked into the otter as well. My reasoning for the raptor is the higher details (sharper corners), less noise and higher depth scanning ability. If I would not already own the Einstar I would bought the otter. The raptor isn't as good scanning bigger parts as the Einstar or Otter. If the reviews are right about this... You are right about the creality software not as good as the Einscan software. The big missing part is the alignment at the end to the coordinate system and the alignment of different scans for fusing isn't as good as with einscan software. Maybe I can import the scan to my Einscan software and do the alignment there? Never tried to load a foreign mesh into the Einscan software before.

@Izaza433 8 месяцев назад

Very nice video. I have the original pop 1 and the range. Do you think this would be good for me? Or unnecessary since I have one scanner for large and one for small?

@LearnEverythingAboutDesign 8 месяцев назад

Well i think if you were going to add another scanner and are ok with being cabled to a computer I would add the Mini. The Miraco is basically a mini and a range in one unit. So the benefit would be more detail using the Near mode and the portability. One thing the miraco can do that others can't is switch between near/far in the same scan. If you look at this post where someone used the Pop and Mini with 2 different scans and put them together, this can be done directly with the Miraco by just scanning the entire thing with far mode, pause the scan and switch to near mode, and capture the detailed areas. forum.revopoint3d.com/t/revopoint-mini-merging-mini-scan-into-a-pop1-3d-model/16324

@MrHandyman00 3 месяца назад

I’ll be using the Miraco scanner to help reverse engineer parts like the turbo in this video. Do you have any videos showing how you got such a clean solid body / component of the turbo in Fusion 360?

@LearnEverythingAboutDesign 3 месяца назад

I have a few videos. Just recently did one with the mini2, but the results would be the same with the miraco on Near mode. Part 1 is prepping for the scan, part 2 is scanning, and 3 is CAD ru-vid.com/group/PLBDfGh8A8kXVLomwHgAg1XeNKdvFv-e1m There are other videos as well. detailed scans of car fenders and so on. The 2 main things are surface prep and enough feature to capture the detail.

@@LearnEverythingAboutDesign I’ll take a look. Thanks, very much appreciated.

@rodiculous9464 8 месяцев назад

Would this scanner be good for detailed scans of gun parts? We're talking small black metal parts with sharp geometry but they tend to have glossy finishes. I figured i would need to use the prep spray. The end goal would be getting accurate dimensions so i could eventually design new parts in cad that would interlock with the existing gun

@LearnEverythingAboutDesign 8 месяцев назад

ummm, errrrr, well it depends on which parts really. I wouldn't suggest getting accurate dimensions off scan data unless you have a high end scanner and are pulling in millions of points for tiny objects. That is something you need to measure. If you are talking less critical parts I think its totally fine. To get super accurate details scans i think you would really be looking at "metrology grade" laser scanners. The cheapest one I know of starts close to $20k.

@rodiculous9464 8 месяцев назад

@@LearnEverythingAboutDesignthanks for responding, sounds like I need to so some more research. The parts would mainly be mounts for optics and lasers which are already a thriving market so other companies must be getting the measurements somehow. I doubt the gun companies themselves are giving out the measurements but who knows, maybe they are.

@LearnEverythingAboutDesign 8 месяцев назад

@@rodiculous9464 Yeah I am not sure really. I have worked in the segment (making knocks for bows) but nothing for firearms. I will say that with scanning for highly detailed items like that you may be better off using a consultant to scan for you and provide you a CAD model as a starting point. Scanning sharp corners will be tricky. If you think about a mesh where points are 1mm apart, getting the corner on a tiny extrusion can be very tough. When i need highly detailed scans I use MotoCilino in GA. motocilino.com/ You might find that spending a small amount getting your parts scanned with an expensive scanner and tools might be a better option.

@Archangel3083 4 месяца назад

Add another scanner for me to flip back and forth over haha. How does this stack up against the Einstar or similar priced units? I like the fact you don’t need to pack around a laptop so not having to buy one makes the $1200 a little more appealing.

@LearnEverythingAboutDesign 4 месяца назад

Yeah :) I will be doing a video on the Mini2 soon as well. The miraco for me checks a lot of boxes. Not having to be tethered to a laptop is a big one. The data transfer over USB for most of the hobby scanners or HDMI for the more professional offerings is a limit to how fast you can capture data(including the laptop they are connected to). The miraco having the processing on board is a big one for me. As for comparing them (miraco and einstar). The miraco has near and far mode giving you the ability to do detailed scans. The einstar doesn't. The einstar seems to do a better job with scanning large objects like Cars pretty well with good detail. I think it comes down to a little bit of the Exscan software. Because the Einstar is the lowest in the Shining3d line it benefits from their software that has a few options revopoint is missing like aligning to a coordinate system and a little more control on mesh processing. So if the only goal was to scan cars (no smaller higher detailed objects) and you had a good laptop and could be tethered to it the Einstar might edge out the miraco. And really the only reason i say that is the Exscan software has a hybrid tracking mode where you can use some markers in areas that are flat and feature based tracking in others. Currently revopoint doesn't have that option.

@waltw918 3 месяца назад

do these scanners scan to scale, how does that work? want to reverse engineer things and also scan in broken parts and use the 3D printer to create replacements.

@LearnEverythingAboutDesign 3 месяца назад

Yes they do. Scanners will have numbers for their precision and accuracy for a single frame. They send out different lights patterns (lines at various thicknesses) and use depth cameras to read back that info. You will find scanners made for larger objects will often have a larger number like .2mm accuracy which means the part its scanning may be .2mm further away or closer to the scanner. Ones for smaller parts or details like here are generally around .02mm. We have a video coming out tomorrow that is part of a 3 part series scanning a part from an rc car. processing the scan, and designing a part to replace it. That might be a good series for you to look at. The video tomorrow is talking about requirements, setting up and collecting scan data. part 2 will be processing the scan data, and part 3 the CAD and 3d print part of it.

@waltw918 3 месяца назад

This would be perfect thanks for the feedback.

@dnoha1 8 месяцев назад

Can it work outside on sunny daylight ?

@LearnEverythingAboutDesign 8 месяцев назад

well. no. Most IR scanners struggle outside in daylight. You can use it outside, but the brighter the daylight the more it will affect the scan. So i wouldn't get it for just that reason. The scans work much better in a light controlled environment.
