3D Printing
A manufacturing technology that converts digital models into physical objects by depositing material layer by layer. It is a core component of personal fabrication and the digital manufacturing pipeline.
Timeline (last 90 days)
Printability is always the practical threshold for STL output, and common checks include whether the model is a closed manifold (watertight), whether wall thickness exceeds the lower limits of the printer nozzle diameter and material strength, whether overhang angles require support structures, and whether the overall dimensions are within the print platform range.
3D-printed parts have problems such as interlayer strength, surface roughness and material safety, and when used for pet products, characteristics such as being non-toxic, bite-resistant and not easily broken must be considered.
Trify3D was originally designed for game developers, but its most active user group comes from the 3D printing community, since non-manifold edges cause 3D printing slicing failures or boolean operation crashes.
3D printing has greatly increased the iteration speed of DIY robots; a design may take only a few hours from modeling to a physical object, but the strength and stiffness of printed parts are usually inferior to metal parts, and they are prone to fatigue fracture under high load or high-frequency vibration scenarios.
Virtual reality in the 1990s and 3D printing in the early 2010s both went through cycles of excessive hype and correction.
For DIY robots, appropriately reducing the center distance and improving print precision when purchasing or 3D printing gears is the most direct means of reducing backlash.
The core idea of 3D necroprinting is to use biological materials as the 3D printing nozzle, rather than conventional metal or ceramic print heads.
With the proliferation of open-source hardware, low-cost sensors, and 3D printing technology, individual developers can replicate bipedal locomotion experiments on a budget of a few hundred US dollars that previously required tens of thousands of dollars.
CNC milling is subtractive manufacturing (cutting away excess material from a solid block), while 3D printing is additive manufacturing (depositing material layer by layer).
The kinematic coupling solution has relatively high requirements for the precision and rigidity of 3D-printed parts, and it is recommended to use metal parts or harder engineering plastics (such as nylon or PC) for critical mating surfaces.
