Additive manufacturing, or 3D printing, creates three-dimensional objects by building them layer-by-layer until the object is complete. Once a 3D printer receives a digital file for printing an object it can then read the data to create the item.
The 3D-printed bongs, including ones shaped like skulls and Nintendo’s Mario, are not the only smoking accessory one can print with the technology, there is also an array of herb grinders, pipes and ashtrays. When the bongs are printed, consumers will still need to buy metal or glass bowl pieces as it is unsafe to smoke from the two dominant 3D plastics, ABS and PLA. While objects can be printed in glass and metals, using these materials in 3D printing is not as pervasive.
With the rapid expansion of 3D printing, maybe eco-friendly and tech-forward stoners will one day be able to print their own accessories in hemp plastic, a smart move to ensure smoking sessions for generations to come.
