Scanning with the iPhone 14 Pro..... then printing successfully...

[V8tiger]

I just upgraded from a Elegoo Mars 3 Pro to the larger Saturn 8k... I realized after a few days the limitations of having a smaller screen which limited me to printing only parts.  the Saturb=n will be here this Weds..... My question now is.. Has anyone actually used their iPhone to scan bodies and parts and completed the process?? From what I understand I have to get a app in order to scan.. the one that comes up the most is Polycam...has anyone used it?  thanks in advance guys... I appreciate it...

Is Polycam accurate?

On most scans, we can ensure accuracy up to 2% assuming that the scan was made under good conditions

 

 

Up to 2% accuracy....essentially 98% inaccurate and not worth bothering with.

You'd do better making a 3D model with Play-Doh.

Ah, the magic of phone-based manufacturing technology.

I messed with this a little, for experimentation’s sake.  Results were about as poor as I expected…the thing I scanned (a resin body) looked good on screen but was WAY to low of a resolution to be useful for anything besides looking at it on a screen.

The technology on phones isn’t there yet (but I would be amazed if any of the printer manufacturers aren’t working on a scanner as we speak…)

There are LIDAR scanners with better scanning resolutions available. The cost plenty o'dough, though.

But will they make me a PB&J sammige when mom's too busy?

I understand they can replicate Welch's Flintstones jelly jars with a 3% +/- 3% accuracy.

Looks just like it.  Where do I sign up?

I looked at the site and I didn't see them saying that the 3d scans were for 3d printing. It is my understanding that that not all 3d scans are intended for 3d printing. Your results are consistent with the suggested usages on polycam website

When you did the scan is there a fixture for the phone to be able to do a 360 degree scan?

This video from Uncle Jessy shows that you can get halfway decent results, but it requires a lot of extra work

Maybe worth perusing...

I'm sorry, I was unclear - I used the iPhone 14 Pro's scanning capabilities, but with a different piece of software ('Kiri' in this case).  I chose Kiri because it's targeted at people wishing to 3d print their scans, and maximizes the available resolution that an iPhone 14 can capture...but it was still not nearly good enough to make anything usable to print.

In my case, used a phone holder to keep the phone steady and a rotating base to revolve the object I was photographing.

I SUSPECT that scanning a much larger object (say, a 1:1 car part rather than a 1:25 car part) then shrinking it down would mask some of these resolution images somewhat...but the technology definitely isn't there just yet when it comes to the iPhone...

[V8tiger]

Thanks Jim I appreciate the feedback....I'm just trying to get a reading on what's available and what's working....

[OldNYJim]

Below is a video of the object I was playing with (half of a dusty old resin copy of the AMT Bonneville kart) scanned with my phone.

Looked surprisingly good on the screen, but as a printable object…no.  I’m sure the technology to achieve this task will be inexpensive and easily accessible in due course, but right now it seems like you’re in the $1000 range just to get started…

From what I understand, most 3D scans require cleanup with Blender or similar programs that fix the resulting model mesh.

Photogrammetry, which uses a large number of photographs of an object, taken from a variety of angles, can result in a model for printing, but much cleanup may be needed.  Sometimes there may be voids caused by incomplete coverage of the subject.  I think a high-quality camera would be best for this.  My own phone's camera resolution is pretty mediocre.

FWIW, here's a phone/PC based 3D scanner that recently appeared in my YT video suggestions, but it's somewhat limited.

 

 

[bobthehobbyguy]

True that some cleanup needs to be done.

However if the resolution is low that cannot be fixed.

A good example of this is digital photographs. Low resolution is fine for the web but not suitable for print.

Still it's still impressive that a scan using a phone can be done. I'm sure that the technology will improve over time.

Doesn't your phone scan your face every time you use it, for the government? (Places tin foil hat back on head.)
