STL Maker is a powerful application that utilizes the TrueDepth sensor found on the iPhone X, XS, XS Max, XR, and the 2018 iPad Pro to create high-quality 3D scans. With STL Maker, there is no need for any scanning attachments, making it convenient and portable.

Users have the flexibility to select the scan resolution, ranging from 1mm to 3.5mm, allowing for detailed and precise scans. All scans are saved directly on the device and can be easily accessed in the Files app under the dedicated STL Maker folder.

One notable feature of STL Maker is that it does not rely on cloud processing. All scan data remains on your phone, ensuring privacy and security. Moreover, the app saves all scans as STL files, which can be effortlessly exported to a computer and converted into 3D printable files.

It's important to note that STL Maker requires an iPhone X, XS, XS Max, XR, or a new iPad Pro with the TrueDepth front-facing sensor to create 3D scans. The app does not support using the world-facing camera for this purpose. Additionally, users should be cautious as deleted 3D models are not recoverable, as STL Maker does not backup or store any data in the cloud.

STL Maker may experience a slowdown in performance after consecutive scans due to its GPU-intensive nature. To ensure better performance, it is recommended to take breaks between scans.

Overall, STL Maker offers a convenient and secure way to create 3D scans using the TrueDepth sensor on compatible devices. With its on-device rendering and storage, users can scan privately and easily export their scans for further use.
