Handheld 3-D printing pens seem like a crummy alternative to those jumbo autonomous boxes , but they involve more patience than most of us can muster , and a comme il faut level of artistic capability . This golem sleeve can help with the latter , by controlling where the pen can move to ensure better result .
Like with a dedicated 3-D pressman , the Guided Hand organisation still requires a 3D model to work from . It wo n’t improve your freehand existence . But if you wanted to recreate theStanford Bunny , the golem sleeve seize to your three-D printing pen provides various types of feedback both guiding the motion of the penitentiary , but also limiting where it can move .
The arm moves freely while the pen is positioned in areas require to make up the 3D model using extruded plastic . But when it attempts to move outside the area pre - define by the root model , motors in the robot ’s arm provide force feedback and physically specify where you could move it . Imagine the feeling of using a swayer to restrain where you could scribble with a marker on a piece of theme . Whenever the marker hits the ruler , it abruptly stop .
At the same time , the robot arm can be used to gently guide the pen where it needs to be , if the user has forgotten to publish an authoritative detail . Or through vibrations and force feedback , it could modify the texture of the plastic being extruded . If you ’ve ever tried to deck a cake with a frosting bag while kids were love on the table , you get the estimate .
The Guided Hand system still has its limits . Since the majority of the 3D impression is still being impart to human hands , the results will never be corresponding to the precision of a dedicated 3D printing machine that takes hr to produce even tiny objects . But for artists looking to dabble in the new mass medium , think of it like a virtual flesh of trace , allow for them to add their own originative flourishes , while still producing a recognizable piece .
