Is Your iPhone Good Enough to Be a 3D Scanner?

For creating 3D printer files, your options include smartphone apps or expensive standalone scanners.

Most 3D scanners are handheld devices that scan small to medium-sized objects with a high degree of accuracy. The resulting files are used for 3D modeling or 3D printing and they can produce fantastic results — if you’re patient and willing to learn how to use them.

These scanners, like the popular Revopoint Pop 2, can cost $700 and have a steep learning curve. Alternatively, if you own an iPhone 12 Pro or higher you can almost recreate what a fancy 3D scanner does. It isn’t quite as accurate, especially for 3D printing, but if you spend some time tweaking, the output can be just about as good.

Creating 3D prints from files uploaded to communities like Thingiverse or Printables is fine, but once you can scan and recreate real-world objects, there’s no limit to what you can create. For example, you could replicate a collectible figure or scan a broken mechanical part to recreate it.

Using a 3D scanner

Pros:

Can capture detail down to 0.1mm
Dimensional accuracy is excellent
Very little clean-up when you succeed

Cons:

Often costs more than a 3D printer
Software is often very hard to use
Creating a usable model is painfully difficult

3D scanners use reflected light — sometimes in the form of lasers — to map the surface of an object. The scanner uses two cameras to judge depth and create a «point cloud» that can be fused together to make a solid object. That solid model is often incredibly accurate down to the smallest crack or imperfection.

But scanning an object can be difficult. The scanner needs to be the right distance from the object you’re scanning at all times, and the object has to be the right color and reflectivity as well. Often, you will need a 3D scanning spray to coat your model in a white, evaporative coating to make scanning easier. This is not possible with human subjects, but does help with inanimate ones. Or at least it should.

I’ve spent hours using 3D scanners and struggle every time to produce a model that could be 3D printed. Often a scan will lose connection, then restart in the wrong place, causing severe disruption. After a lot of trial and error, I’ve managed to get several usable models, but the amount of work it took just didn’t seem cost-effective.

Using your iPhone

Pros:

Incredibly fast scanning
Models are instantly usable as online resources
You likely already own one

Cons:

Lower detail and quality
Can need a lot of clean-up to make it 3D print-ready

iPhones have a lot of cool technology that makes them excellent 3D scanners, including good cameras for photogrammetry and lidar technology for larger objects like cars or the inside of your home.

Photogrammetry is the best way to create a fully realized 3D model if you want that model to only exist digitally. It uses multiple pictures — the more pictures the better — to create a realistic facsimile of an object. The depth mapping is far rougher than a 3D scanner, but the textures and photo imagery make the model look extremely detailed. As you can see, the shoe in the image above looks identical to the real thing when the textures are shown, but the model I 3D-printed from it has lost a lot of its details.

The coolest thing about photogrammetry, especially on an app like Polycam, is that it can be used with any camera you have, including DSLR cameras and even drones. You simply upload as many images as you want to the Polycam app and it will spit out a 3D rendering of the object you took, whether that’s a shoe or the Grand Canyon. It even works with Android phones, though none of those have the lidar technology like the iPhone.

Lidar only works if you have an iPhone 12 Pro or later, but it’s excellent for scanning larger objects like mailboxes, pool tables and even cars. It works a lot like an expensive 3D scanner — by bouncing light off an object and measuring the distance the light travels — but it has a much lower resolution. This makes it excellent at scanning large, simple objects, especially if you’re keeping them as digital models.

Both photogrammetry and lidar imagery are extremely easy to use on your iPhone and require very little technical know-how to get right. They both need an app though, and after using several different ones, I found Polycam is the best choice.

Polcam for iPhone and Android $80 at Polycam

Polycam costs $80 a year and offers both lidar and photogrammetry. More than that, it uses those systems in some really fun ways. Not only can you scan objects to create 3D models, but you can scan the walls inside your house and build a 3D floor plan. You can even 3D print that floor plan complete with walls, stairs and window and door openings.

When scanning an object on Polycam for 3D printing I was able to get good quality, low-resolution scans for organic shapes and much better scans of simple objects. Using Polycam to scan a broken sliding door handle was quick and simple and allowed me to accurately replicate a replacement. In fact, if you’re used to using programs like Blender — a free 3D sculpting tool on the PC and Mac — or Nomad Sculpt on the iPad or iPhone, you can import the Polycam file and spruce it up before printing.

Should you buy a 3D scanner if you own an iPhone?

I’ve spent a lot of time with several different 3D scanners and they all have the same inherent flaw: They’re just too picky to work for consumers. In a commercial setting, where everything can be controlled and your day is dedicated to getting this machine to work perfectly, then sure, a 3D scanner makes sense. If you’re a hobbyist though, with a life that requires more from you than endless hours of slow scanning, an iPhone is a better option.

Even if you don’t own an iPhone, you can pick up an iPhone 12 Pro — the first with lidar — for around $550, several hundred dollars cheaper than a 3D scanner. And once you’re done 3D scanning shoes, mailboxes, cars and houses, you still have an iPhone that can do a hundred other things too.

The Motorola Razr Ultra 2025 is the company’s competitively priced foldable phone. You can pick one up with 1TB of storage for $1,300, which is $200 off the regular price and available in a variety of colors and finishes. If you prefer the Motorola Razr Plus 2024 model instead, you’ll find that starting at $799, again $200 less than the typical retail price. We spotted this same deal at Amazon right now as well, if you prefer to shop there.

And for the most wallet-friendly phones, the Moto G phones make a great option. These already super-affordable phones are now even less, including the Moto G Power 5G 2024, which is $210 at Amazon or at Motorola, a price that falls $90 below the regular cost.
