Yet ANOTHER Machine Vise

pinshape

This is an incredibly sturdy 3D-printable machine vise that's 100% 3D-printed. No screws or other hardware are needed to hold the individual pieces together - instead, they clip and snap into place seamlessly. It's a clear demonstration of just how crucial it is to consider forces and material properties from the very start when designing mechanical objects. Hints about proper design can be found in my video at https://youtu.be/mziT7KV-fRI, which also includes step-by-step instructions on assembling this vise. For optimal 3D-printing results, I recommend printing with three shell layers and a 35% infill - more infill than that won't make the vise any stronger. The forces for clamping workpieces are only active at the outer surface. When it comes to layer height, I've found that 0.15 mm works well (though screws might benefit from even thinner 0.1mm layers). You won't need support material, and a 0.4 mm nozzle is ideal for printing this vise. I designed it using Fusion 360, which can be accessed at http://a360.co/2juhSUG. Standards NGSS Overview and Background When trying to 3D-print common mechanical objects, people often forget that the traditional shape of these objects may not be 3D-printable. Even if an object is successfully printed, it might not work properly or be strong enough. For this reason, adapting your design based on its intended use is essential. If you're familiar with CAD tools and create designs for 3D-printing, I highly recommend considering the unique material properties of 3D-printed parts. Lesson Plan and Activity To learn more about designing better 3D-printable mechanical objects, I suggest watching my video on YouTube. With this knowledge, you'll be able to create your own c-clamp, pliers, stands, geared transmissions, camera mounts, and more. Materials Needed A spool of PLA or PETG filament, a 3D printer, and some CAD software like Fusion 360 or Tinkercad will get you started.
