3DMart is happy to try out various materials and 3D printing tests for you. Regular sample cards are too bland and don't show properties like toughness and strength, so we created a multi-material boxing gun! You probably all saw this toy when you were kids. Don't underestimate this small boxing gun; it combines six different materials! Each material has its own suitable function. Additionally, we designed a hollow viewing window in the structure so everyone can clearly see how the boxing gun works:
The main retractable grid is made of Tough PLA, which has similar strength to ABS and is less prone to brittleness, making it suitable for functional parts. The modular gun handle parts are made of Nylon and ABS. In addition to their robustness, Nylon also offers elasticity and toughness, making it strong enough to withstand stress at the pivot point. The gun handle sleeve is made of elastic TPU, which can better adapt to shape changes. The green retaining pin uses CPE, which has temperature resistance and mechanical strength, making it suitable for objects and mechanical parts. The fist is most often subjected to external impact, so high-strength PC was chosen for 3D printing.
This time, we primarily used Ultimaker's original filaments. Normally, different materials require considering different shrinkage rates, but because Ultimaker printing is dimensionally accurate and Cura slicing software has preset parameters, the combination of these parts remains excellent. Of course, the advantages of Ultimaker's dual nozzle system also played a crucial role, allowing us to utilize PVA water-soluble support material. Simply placing it in water yields precise dimensions and a beautiful surface.
These are the seven parts after 3D printing. Now, let's assemble them according to the diagram:
First, place the rubber bands, green retaining pins, and retractable grids into the handle's slots. Then, add the perfectly symmetrical rubber bands and retaining pins on the other side.
Close the black ABS gun handle, ensuring each slot is precisely aligned, and finally, put on the fist and holster to complete it!
Interested in 3D printing technology? 3DMart will be holding 3D printing workshops after the Chinese New Year, where you can also see this boxing gun! Let's get printing in the new year. Click here to register online! Seats are limited, so register before it's full!
We will continue to share new information and practical tests related to 3D printing! All the latest news will be announced on our Facebook page!
