There are many inventive hobbyists who are making very good use of the 3D printing knowledgesphere. That knowledge includes hardware, software, electronics, design, tools, models, examples, help, tutorials and services. For those who are not satisfied with the current offerings, they often dig in deep in attempts to find better solutions by leveraging all available resources.
One such example is Replibot, where we find numerous posts on various experiments including detailed descriptions and images, all intended to improve the techniques. Their discoveries and improvements make their way back into the knowledgesphere where they are then used by others in a continual process of improvement.
Where will we be in five years?
