STL Maker uses the TrueDepth sensor found on the iPhone X, XS, XS Max, XR and the 2018 iPad Pro to create 3D scans. No need to carry a scanning attachment. Users can select scan resolution from 1mm to 3.5mm. All scans are saved on your device and can be accessed in the Files -> STL Maker folder on your phone. There is no cloud processing of scans and all scan data remains on your phone. Scan as you please, privately. All scans are saved as an STL file which can easily be exported to your computer and converted to a 3D printable file. All rendering is done on-device and there is no need to register or store files in the cloud. There is no charge for saving scans. Notes. 1. STL Maker requires an iPhone X, XS, XS Max, XR or new iPad Pro to create scans since it depends on the TrueDepth front-facing sensor. There is no option to use the world-facing camera to create 3D scans. 2. If deleted, a 3D model is not recoverable. STL Maker does not backup or store any data in the cloud. 4. STL Maker is GPU intensive! You may notice a slowdown after your 5th or 6th scan in succession. Your iPhone is smart enough to slow its processing down during repetitive intensive operations. Taking time between scans will offer better performance. 5. All 3D scan data, processing, and storage take place solely on-device in STL Maker. Scan as you please, privately. ## Key features - 3D scanning with TrueDepth sensor - Adjustable scan resolution - On-device processing and storage - Export as STL files - No cloud required - Private scanning ## Recent user reviews (10 of 17) All indexed reviews: https://appshunter.io/ios/app/stl-maker/id1444230836/reviews.md ### 4/5 — Wow *2021-05-16* To have software like this on a phone is amazing. My only reason for 4 stars is that I can’t seem to open a saved file again, not sure if this is just a bug. Other than that, it’s fantastic. ### 1/5 — Money Back Please *2021-02-20* This app is not worth the money as you can’t use the forward camera. It also slow and keeps crashing. ### 1/5 — I would like a refund *2020-11-17, version 1.5.7* Barely functional. ### 1/5 — Waste of money *2020-08-16, version 1.5.3* It doesn't do a good job scanning at all. Waste of money I wish I could get my money back. **Developer response:** We are sorry for your experience with STL Maker. Please check out this tutorial on getting a good scan on YouTube: https://www.youtube.com/watch?v=-rVRdd-q9yM ### 1/5 — Uses the selfie camera. Impossible to use for scanning objects *2020-07-12, version 1.5.3* Useless **Developer response:** Please see our YouTube channel for scanning tips: https://www.youtube.com/c/Scandy3D Getting good scans is very easy with a few simple methods. ### 1/5 — Alpha version at best *2020-04-13, version 1.5.3* If I could check this app before paying the $10, I wold never buy it. I cannot make a single scan as the tracking stops working before I can finish the 360 degrees rotation. Also the saved files cannot be re-open or deleted from the app. Even the file info shows the date only and no time, so it is difficult to even figure out what to share. Although, on the other hand, the quality is so bad that northing really to share. And this is not only the noise, but distortions and incompleteness of the images. Even if the app was free, I would delete it after wasting an hour or so. It’s shame to charge money for this nonsense. ### 3/5 — iPad Pro 2020 support *2020-03-26, version 1.5.3* When are you planning to support world-facing camera with Lidar sensor? **Developer response:** As soon as Apple provides access to the depth map generated from the Lidar sensor. ### 4/5 — Good app but I wish it let you switch to the front facing camera *2020-02-17, version 1.5.3* The scans of my face are coming out well but that’s just about all I can scan with the inner camera. If it would allow you to switch to the front facing camera and scan anything else that would be excellent! **Developer response:** there is no depth sensor on the world facing camera, so we cannot provide that functionality. ### 4/5 — Useful app but still missing .5mm *2019-10-13, version 1.3.1* Really great app for what the allow you to do with it. You said in June you’d add .5mm resolution in the next update, but last months update didn’t have it. Really disappointing that this is still a downgrade of the ScandyPro, .5mm makes a huge difference. Also wish I could actually look at the library in 3D after saving the files. Seems silly there’s only thumbnails. I’ve done multiple scans of the same item and couldn't review them later to see which was better without moving them to a PC. Still love the app tho, great work. **Developer response:** We've updated the app and 0.5mm resolution now works again. Thank you for your patience! ### 4/5 — Great Potential *2019-08-04, version 1.3.0* Just scan an item into Fusion 360 and the dimensions are basically correct. I would like to see some basic cropping/editing features before I save the file. Also, it is not clear if I should rotate the phone or the object. Add the ability to remotely stream to another device while scanning. Add different output formats. **Developer response:** You can get basic cropping and editing features in Scandy Pro. The app and the editing features are free, and you can import your scans from STL Maker into Scandy Pro. ## Frequently asked questions about STL Maker ### What devices are compatible with STL Maker?
