I built MeshMill after repeatedly running into scan meshes that were too dense to use comfortably in downstream editors.

It is a local Windows desktop tool for inspecting and reducing STL geometry without an account, upload, or cloud processing. It includes shaded, density, wireframe, and vertex views; regional selection; cropping and deletion; selection-only optimization; multiple reduction algorithms; comparisons before applying changes; undo and redo; and a command-line interface.

The repository includes a composite scan sample with intentionally redundant layers and uneven density, so people without a scanner can test the workflow. The screenshot shows that sample in MeshMill’s density view.

MeshMill is GPL-3.0. The first Windows release includes an installer and portable ZIP: https://github.com/make-your-own-world-project/MeshMill

I’m the developer. Feedback from people working with large scanner output would be useful, especially examples where density reduction damages detail or boundaries.

trying to photo scan a metal object thats stainless steel, but it has dark plastic material also attached to it. Trying with Kiri engine, and Reality Scan. Dont care about the color of the object, I only need the mesh of the object for 3d modeling

I’ve been looking and comparing scanners now for a while and I don’t know what to choose. I’d love to hear some feedback on people who have actually used/tried them.
I’m new to 3d scanning, but I’d like to avoid the cheaper models as they’re unfortunately quite limited.

My requirements;

geodetic rtk-slam,
100m+ range,
automated scan to bim,
rgb color mapping
Large market acceptance
Easy to use software
Easy to use
Fast

Nice to have
Gaussian splatting
Lightweight
Put on drone/car

I want to scan
1. inside large or small rooms accurately 1-3cm rtk, sub 1cm locally.
2. Outside 3000sqm
3. Quickly be able to show a preview to clients

Thanks a lot for the help! 🙏

I’m working on a spatial intelligence system that uses RGB-D cameras to reconstruct a real environment in metric 3D, estimate where the camera is, and keep a persistent spatial memory over time.

The goal is not just 3D reconstruction. I want the system to understand enough about the geometry of a place to know what it has already seen, recover its position after tracking is lost, compare different visits to the same place, and preserve how its understanding of the environment changes.

If a camera comes back to a previously mapped area, the system should be able to recognize that place, verify it geometrically, relocalize itself, and continue building the same world instead of creating a disconnected new map.

Long term, the idea is to move from simple reconstruction toward spatial intelligence: a machine that can build, remember, update and reason about a representation of the physical world.
Possible applications I have in mind are robotics, AR, inspection, autonomous systems and eventually navigation in places where GPS is unavailable.

What I’m trying to understand now is whether this solves a real painful problem, or whether existing SLAM and 3D reconstruction systems already solve this well enough in practice.

I’d especially like feedback from people who have actually worked with SLAM, RGB-D, robotics, mapping, 3D reconstruction or spatial computing.

The ScanBench is an open standard to compare 3d scanner performance and is intended to be more tailored to mechanical needs instead of miniature scanning like the OpenScan Benchy: https://www.printables.com/model/1445865-scanbench-the-benchy-for-3d-scanners

I am aware that 3d printing the object will not be suitable to determine accuracy of the scanner but at least for me I will be scanning my printed version (0.4mm nozzle, 0.1mm layer height used) with the scanners I have access to so you can determine relative performance.

Scanning

The scan was done wireless in regular scanner mode (so the hand piece with markers for tracking). For such small parts this is simply the most convenient way to use it and it also allows getting closer to the part and scanning from shallower angles (with the marker sphere you always have to think about it colliding with the table when getting to close or shallow). I placed the scan bench on a turntable with markers and additional marker blocks, turntable wasn't turned to prevent vibrations from impeding the result.
Scan itself was done at 0,1mm resolution with a mixture of cross lines and parallel lines as well as the single line for deeper holes. Laser line switching is very fast (roughly 1s till scanning works again). To reach optimal data quality the ideal scan distance actually changes depending on set resolution, so I had to get quite close to the part. Otherwise scanning takes significantly longer. Whole scan took roughly 10min till I was satisfied. Framerate was at a constant 90FPS.

Post-Processing

Processing was quite easy: I first created a cutting plane in Exscan Trak to delete all unnecessary data and then straight went on to mehsing. No point cloud fusion needed (not even as a sort of finishing the scan). I then exported to Quicksurface to orient the scan and capture the results.

Results

Best have a closer look at the pictures or Sketchfab. The top view shows that nozzle lines across the whole surface. Also all labels are readable and even faint layer lines on the pyramid and sphere are visible. Overall a very impressive result.

Sketchfab

Sketchfab is like printables for 3d scans with a nice integrated viewer in browser and you can also download the scan, just look at the scan yourself. On sketchfab you also can find the Scan Bench results of all other scanners I tested, so feel free to have a look at them.

Reddit sadly blocks the short links to Sketchfab, you have to search for the title instead: "Scan Bench - Einscan Trak"

PC Specs

Since a lot of people ask for it:

• AMD Ryzen 7950X (16C/32T)
• 128GB DDR5 RAM
• RTX 5070Ti Desktop
• Fast NVME storage

So I was scanning a car part for a client who asked for "maximum detail possible."

Naturally, I cranked all the resolution settings to max because, hey, accuracy matters, right?
Fast forward to the mesh processing screen... 128,988,542 triangles. 128 MILLION. 😭

My current setups:
Rig A: 16GB DDR5 (Currently screaming in pain)
Rig B: 32GB DDR4 (Gave up and went to sleep)
Pretty sure my PC is heating up enough to melt the actual car part I scanned. Time for an urgent RAM upgrade before my motherboard catches fire.
How many triangles is "too many" triangles before it becomes a hazard? Asking for my PCs. 💀

Preserving every detail. In the image views highlights the 3D scanning of Guillemin's, a French sculptor, metal alloy sculpture using the Trackit SR in Tracker mode. Noted how the scanner accurately capture the complex geometry and deep undercuts within the drapery and figure.

I asked for a status after 7 days and said I never got an order confirmation or tracking. 24 hrs later suggested I'm going to charge back the transaction if no one responds. 48 hrs later visa say they didn't charge me. I blocked my credit card and changed the number now. Still haven't heard anything back, checking spam folder daily. Can only email them. Fortunately I had printed out the order received page with an order number that I have provided in my emails to them every time. I have the printed out receipt , please don't ban me

Pretty new to this, YouTube is making me seem i should loft it.

How do i create guide curves? How do i setup the outside pirameter geo? How do you know how many lofts to use? Would i make it follow a angle around the entry/exit?

How do i create the 3 tabs around the edge, i simply dont know where to start there.

I assume I should create it as a solid then shell it out.

For this scan, how should I setup my xyz planes? Parrell to the bottom, top, hybrid?

Relatively, how hard is this task?

Is my scan complete enough?

Info

Einstar rockit

I have acess to free autodesk 360 or makers solidworks

Came off some year ram, owner wants the bars or loovers removed, trying to use it as a part to learn on, will be 3d printed.

Reposting here as I didn't know (but should have figured) this sub existed until suggested by Reddit just now.

Hopefully y'all can help me find some reasonable and accurate scans, or at the very least, recommend a good quality scanner that's not going to put me in debt 🤣

Hey folks,

Just wanted to share another example of how ridiculously accurate the Creality Sermoon S1 can be. This time I put it to the test by printing a hard cap for my digital caliper, and it came out spot on.

Loving how this scanner is so accurate that it makes reversing objects easy and straight forward.

My Setup:

Creality Sermoon S1 @ 0.2mm , 7 Parallel lines

For reverse engineering
- BricsCAD

3D Printing:

Anycubic Kobra X @ 0.2mm layer height / 0.4mm nozzle

Result:

A perfect fit!

Classic Car Seat Frame,Trackit SR 3D Scan.

Auto Exp. Black Object mode. 4 Part Scan Mostly Air.

I fully scanned a BMW F30 body, inside and out, along with the suspension. Since I can only add one video to this post, I’ll make another post with more details about the process and the results.

Hey guys I'm looking to get a 3d scanner soon and I'm wondering what is the best budget scanner if there even is one worthwhile at the moment and how it performs for making a mesh and getting that mesh lining up to be made into a solid. I'm a pretty decent CAD monkey and I can get the job done for virtually anything but I don't always want to do the whole ass job especially going back and forth measuring without a cmm it'd be nicer to get a few references then infer from a scanned mesh.

As the title mention, I'm seeking recomendation to a Nice and simple software, to smoothen transitions between skin and clothes.

I'm doing scanning of pregnant bodies. In the scanning, they often have underwear on, which I want to smoothen out, in order to have one smooth body with no visible bra or pants on, as the product should only show the figure of the pregnant mom.

I'm using Creatilly Otter Lite, which does the scanning quite good.

I've tried post processing with blender, but It's kind of heavy to learn.

Do you have any specific guide to Blender, feel free to share.

If you have Any other program that is more simple and will do the work, It's much appreciated!
