New Mexico State University: teachers in 3D printing school

New Mexico State University has completed the first edition of the AMPD program, dedicated to training K-12 teachers on additive manufacturing. The initiative, organized by the DREAM Research Center, involved teachers from the

Practical guide to building a tool changer system for 3D printers with less than €30 and a weekend of work. Discover which components to buy, what to print, the critical tolerances to respect, and common errors to avoid to build a functional DIY tool changer.

Guide to creating functional 3D fidget toys: choose tested models, use print-in-place and snap-fit with tolerances of 0.2-0.3 mm, and suitable materials: PLA for rigid clickers, PETG for stress, and TPU for soft grips. Calibrate the printer for durable results.

Refactoring 3D models without breaks: verify hierarchical constraints, test dependencies, and validate the STL. A three-level system to maintain parametricity and integrity before production.

Bambu Studio 2.5.3 introduces Color Mixing: create custom shades by combining 2-3 filaments of the same type. Thanks to a software-controlled optical effect, it generates uniform colors or gradients without purchasing new spools. Requires compatible and translucent materials for optimal results.

The new color mixing tool in Bambu Studio allows you to obtain infinite shades by combining different filaments without physical fusion, leveraging the controlled alternation of layers. Through the Add Mixed Filament function, it is possible to create custom gradients with a few spools, ideal for visual effects and soft gradients. The result depends on the Transmission Distance and the geometry

Here's how to integrate touch keys into your 3D printed objects using self-adhesive copper tape and scheduled pauses during printing. Working capacitive sensors are created with simple measures: three-layer depth positioning, holes for electrical connections, and post-print soldering. An economical and accessible solution for integrated touch interfaces.

Optimizing nozzle and G-code is essential for precise 3D printing. The choice of nozzle diameter, extrusion calibration, and the correct use of G1, M109/M104 commands allow for avoiding defects and improving quality. Advanced techniques like Blender simulation and custom nozzles open new possibilities in areas such as food or ceramics.

Updating printer firmware and software is essential to prevent errors, optimize materials, and improve efficiency. Neglecting them can cause waste, interruptions, and a drop in quality. Following an accurate procedure, with testing and backups, allows you to fully leverage technological advantages and extend the life of the machines.

Integrate free or premium 3D resources into your educational or consumer projects to accelerate development and innovation. Choose suitable platforms, verify quality and licenses, and optimize the workflow for professional results.

3D modeling tools are revolutionizing youth education, making STEAM learning more visual, interactive, and engaging. Through intuitive interfaces and complete design cycles, students transform ideas into physical objects, developing technical and creative skills from primary school. Software like BlocksCAD and SelfCAD combine geometry, coding and s

Quick guide: choose the right CAD to print in 3D without errors. From free models (Tinkercad, Fusion 360) to modeling rules, you get to optimized printing in a few hours.
