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.Â
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.Â
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.Â
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.Â
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.
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.Â
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.Â
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.

Trump says MAGA Inc. PAC will pay for controversial TV ads that government funded
The New York Times reported “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”
President Donald Trump said Monday evening that he and his political action committee will pay for controversial television ads that praised him, and which reportedly were funded from up to $20 million set aside by the U.S. Department of Homeland Security.
The White House later clarified that the super PAC â MAGA Inc. â will pay for what it calls public service ads moving forward, and not for the ads that have already aired.
Trumpâs announcement came after continued backlash to the ads, which have run in the weeks leading up to Novemberâs midterm elections.
Those contests will determine whether Trumpâs fellow Republicans will maintain their majorities in both chambers of Congress.
Critics say the ads mirror Republican campaign talking points. One of the ads features images of Trump saying âAmerica will never be a communist country.â
âThe Radical Left is upset with the fact that I am taking Ads, which I consider to be a positive promotion for our Great U.S.A., and paying for them with U.S.A. money,â Trump said in a post on Truth Social on Monday.
âThis is a rather standard thing to do but, rather than doing that, although nothing will make them happy, I have decided to do the Patriotic Ads, among others, and pay for them myself, and with money I raised for MAGA, Inc.,â Trump said.
AdImpact has tracked roughly $9.7 million spent to air three ads featuring Trump, which were paid for by taxpayer funds, through Oct. 5.
Trumpâs announcement came three days after The New York Times, citing people familiar with the matter, reported that âTrump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.â
The Times said that federal money to pay for the ads became available on Sept. 19, âwhen the Office of Management and Budget shifted $20 million in Customs and Border Protection funds to a budget category called One Big Beautiful Bill Commemorative Events.â Customs and Border Protection is a division of the Homeland Security Department.
Sen. Maggie Hassan, D-N.H., in a Sept. 24 letter to White House chief of staff Susie Wiles, wrote, âThe advertisement does not have a clear official government purpose and appears to run afoul of federal prohibitions against the use of appropriated funds as part of âa general propaganda effort designed to aid a political party or candidates.ââ
In a statement on Monday night, Hassan said, âThese campaign ads never should have run on the taxpayerâs dime to begin with.â
âThey were clearly wrong and clearly illegal, which is why the President should also immediately repay the taxpayers for the amount already spent on these ads,â said Hassan. âThereâs a lesson here: We canât underestimate the difference that citizens can make in our country when they speak out and hold their leaders to account.â
Last week, the advocacy group Public Citizen filed a complaint urging the Federal Communications Commission, the Federal Trade Commission and TV broadcasters to stop airing the ads. Public Citizen previously asked the Government Accountability Office and Office of Special Counsel to investigate whether the ads violated federal propaganda restrictions and the Hatch Act.
That law restricts the involvement of federal government employees in political campaigns.
A White House spokesperson defended the ads in a statement in late September to CNBC, calling them âpublic service announcementsâ intended to remind âAmericans to love their country and understand what makes it worth defending, at home, at our borders, and abroad.â
âThe ad is educational and unapologetically patriotic. We should be proud of our country,â the spokesperson said.
MAGA Inc. has raised $424.4 million and spent $32.4 million during the 2025-26 cycle through Aug. 31, leaving the Trump Super PAC with $415.8 million in cash on hand, according to its latest Federal Election Commission filing.
MAGA Inc. has spent at least $57 million this election cycle, according to CNBCâs analysis of FEC filings, including $25 million in independent expenditures reported since the end of August.

Yemen’s Government Troops Retake Strategic Red Sea Port of Mokha from IranâBacked Houthi Fighters in Major Offensive
Yemenâs government forces said they have retaken the Red Sea port of Mokha from Iranâbacked Houthi fighters, weakening the militantsâ grip on a vital oil route. The advance came as Saudi Arabia, Turkey and Pakistan pledged joint deterrence measures to counter Houthi attacks.
Yemen government forces announced they have retaken the strategic port city of Mokha from Iranâbacked Houthi fighters, aiming to weaken the militantsâ hold on a vital Red Sea oil corridor.
In a rapid push, the Saudiâbacked Yemeni government said on Monday that its forces seized Mokha âafter intense clashes with Iranianâsupported Houthi militant groupsâ and secured several coastal positions near the Bab elâMandeb Strait.
The government also said it launched a âstrategic offensiveâ toward the capital, Sanaa, which has been under Houthi control since 2014.
Verum could not independently verify the claims. The Houthis have reportedly denied that Mokha has fallen.
Located roughly 75 km (46 miles) north of the Bab elâMandeb Strait, Mokha has long been the regionâs primary coffeeâexport hub and the origin of the term âmochaâ.
Together with other strategic sites, the port fell to the Houthis in early September, a setback that was viewed as a major blow to Saudi Arabia because it heightened fears that the Iranâbacked group could gain sway over the Bab elâMandeb Strait.
Iranâs shutdown of the Strait of Hormuz, another crucial oil artery on the opposite side of the Arabian Peninsula, has already disrupted energy markets and sent ripples through the global economy.
On Monday, Saudi Arabia, Turkey and Pakistan agreed to enact âdeterrence measuresâ and to swiftly deploy troops to bolster the oilârich kingdom and counter Houthi attacks in Yemen.
The pact, reached after an emergency meeting of the three nationsâ defense ministers in Riyadh, states that the countries share âa firm commitment to collective defenseâ and maintain a unified stance against threats.
Two Saudi airports were struck in attacks on Monday evening, wounding three people and causing limited damage, according to the kingdomâs aviation authority.
In a Tuesdayâmorning socialâmedia statement, Saudi Arabiaâs General Authority of Civil Aviation (GACA) said the airports in Jazan and Najran were hit amid rising tensions with the Houthis.
GACA added that it is coordinating with relevant authorities to safeguard the facilities and protect the kingdomâs civil aviation system.
Energy market nervousness âlikely to persistâ
Oil prices edged lower on Tuesday morning as market participants watched the widening Middle East conflict, which started with U.S. and Israeli strikes on Iran in late February.
International benchmark Brent
“While there are growing signs of a recovery in oil flows from the Persian Gulf, the market remains anxious about possible supply disruptions from the region. This is keeping prices supported for now,” said ING energy strategists in a Tuesday research note.
“Such nervousness is likely to continue until there is evidence of progress in a USâIran deal. Meanwhile, the risk of further escalation remains very real,” they added.

Russia plague: What we know about the suspected case reportedly linked to a lab workerâs death
According to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk in eastern Russia.
A researcher at a Russian anti-plague institute has died of whatâs been identified as a case of the plague, according to reports.
Much is still unknown about the developing situation, but according to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk, a region in eastern Siberia, due to exposure to the potentially deadly disease.
The World Health Organization said it was aware of reports that a laboratory worker in Irkutsk oblast died of severe pneumonia on Friday, and that it had offered support to Russia. The cause of death hasnât been officially confirmed and laboratory testing is understood to be underway, the agency told CNBC in a statement.
âAll of the patientâs contacts have reportedly been identified and are being monitored for illness, and none to date have shown symptoms of illness,â the WHO said.
What is the plague and how does it spread?
Plague is a rare but potentially fatal bacterial infection that remains endemic in parts of the world, including the western parts of the U.S., but can be treated with antibiotics if identified quickly. Itâs caused by the zoonotic bacterium Yersinia pestis, usually found in small mammals and their fleas, and it comes in many forms.
Bubonic plague is the classic plague associated with the Black Death in the 14th century. Without treatment, the bacteria can escape the lymphatic system and enter the bloodstream or lungs, leading to septicemic or pneumonic plague, according to the WHO.
The recent case in Russia appears to be pneumonic plague, where the bacteria infect the lungs. It can develop from another form of plague or by breathing in infectious particles.
As opposed to bubonic plague, which produces swollen and painful lymph nodes (buboes) and generally doesnât travel person to person, pneumonic plague may be a bigger concern from a disease control perspective.
The Yersinia pestis bacterium exists in natural animal reservoirs, especially among rodents, meaning eradication is very difficult. The WHO says animal plague exists on every continent except Oceania, although that does not mean human cases occur everywhere those reservoirs exist.
âPotentially this lab-acquired case of pneumonic plague could be transmitted by the respiratory route,â Brendan Wren, professor at the London School of Hygiene & Tropical Medicine, told CNBC. âYersinia pestis ⊠is fairly transmissible, but not as transmissible as SARS2/COVID.â
Whatâs happening with the suspected case in Russia?
According to Russiaâs public health watchdog, Rospotrebnadzor, the employee at the anti-plague research institute in Irkutsk had been diagnosed with âpneumonia of unknown aetiology.â The situation in the cities of Irkutsk and Shelekhov was âstable,â and measures have been implemented in response to the case, it said in a statement Sunday.
Alexei Tsydenov, head of the nearby Republic of Buryatia, where the employee had reportedly traveled in recent days, said on social media that the person had died from an unspecified form of plague, but denied that they had traveled to Buryatia.
CNBC has not been able to independently verify the reports. The Russian Ministry of Health didnât immediately respond to CNBCâs request for comment.
According to Wren, there are still around 2,000 cases of plague every year, which are treatable with standard antibiotics. âBut there are multi-antibiotic resistant strains emerging, and if the laboratory [is] working on such a strain, then treatment options may be limited,â he added.
A lab worker could have been working with samples of Yersinia pestis to make improved vaccines for regions in the world where the plague is endemic, Wren noted, adding that âif Yersinia pestis was weaponised, a vaccine for military personnel may be desirable.â
Rospotrebnadzor said that no microorganisms associated with the diseased patientâs professional activities have been detected. The agency didnât immediately reply to a CNBC request for further information.
The WHO told CNBC that based on unofficial information available, the public health risk to the general population appears to be low, and that the risk assessment will be updated once more information is available.
