A 3D scanner suitable for moving people would need to be portable, fast, and capable of capturing accurate and detailed 3D scans of a person in motion. One option that fits these criteria is the Artec Eva 3D scanner, which is handheld, lightweight, and can capture high-resolution 3D scans in real-time. Another option is the Structure Sensor, which can be attached to an iPad for on-the-go 3D scanning and is capable of capturing full-body scans of moving subjects. Lastly, the Shining 3D EinScan-Pro is a versatile handheld 3D scanner that can capture both static and dynamic 3D scans, making it suitable for scanning people in motion. **

Your 3D printer may be moving in the wrong direction during homing due to incorrect wiring or configuration settings. Check the wiring of the stepper motors to ensure they are connected properly and that the polarity is correct. Additionally, review the configuration settings in your 3D printer's firmware to ensure that the direction of movement is set correctly. If the issue persists, consider recalibrating the printer or seeking assistance from the manufacturer or a professional technician. **

No, the Unity 3D project has not disappeared. Unity Technologies, the company behind Unity 3D, continues to actively develop and support the platform. Unity 3D remains a popular choice for game development and is used by many developers and studios around the world. The platform regularly receives updates and new features to improve the user experience and capabilities for creating games and interactive experiences. **

Yes, it is possible for a small 3D printer to print the parts for a larger 3D printer. This process is known as "self-replicating" or "reprap" 3D printing, where a 3D printer is used to create the components for another 3D printer. As long as the smaller printer is capable of printing the necessary parts for the larger printer, it can be used to create a larger 3D printer. This allows for the potential for exponential growth in the number of 3D printers. **

The 3D printer may not be moving in the Y and Z axis due to a mechanical issue such as a jammed or broken belt, a loose or disconnected motor, or a problem with the stepper motor drivers. It could also be caused by a software issue such as incorrect settings or a malfunctioning control board. It's important to troubleshoot and diagnose the specific cause of the issue in order to fix the problem and get the 3D printer moving properly again. **

Home Design 3D is the basic version of the app that allows users to create floor plans and design their homes in 3D. On the other hand, Home Design 3D Gold is the premium version that offers additional features such as unlimited access to the catalog of items, advanced rendering capabilities, and the ability to customize textures and materials. Home Design 3D Gold provides a more comprehensive and enhanced experience for users looking to create detailed and realistic home designs. **

Building a DIY Arduino 3D printer requires a few key components such as stepper motors, a hotend, a heated bed, and an Arduino board. One can start by assembling the frame using aluminum extrusions or 3D-printed parts. Next, wire the stepper motors to the Arduino board and connect the hotend and heated bed. Then, install the necessary firmware onto the Arduino board and calibrate the printer. Finally, test the printer by sending commands from a computer to ensure it functions correctly. **

The size of a 3D model for online shops for 3D printing depends on the specific requirements of the shop and the capabilities of the 3D printers they use. Some online shops may have size limitations for 3D models, so it's important to check their guidelines before uploading a model. If the 3D model is too small, it may not meet the minimum printing requirements of the shop, and if it's too large, it may not fit within the printing volume of their machines. It's best to ensure that the 3D model meets the size specifications of the online shop before uploading it for printing. **
