DIY Mobile Laser Cutter in 3D Printed Frame by Josh Hughes

Josh Hughes is developing a DIY handheld mobile laser cutter and engraver in 3d printable housing. In theory with this device, you would not be limited by a surface and it could work on a battery power.


Here is a design study:





Here is a model of 3d printable enclosure body, the design is now more refined with more ergonomic side handles:



Here is a prototype working with, what seems like, salvaged laser diode and optical drives:




You can follow the process on developers YT channel:

D-Coil handheld wax extruder for manual 3D printing

From project description:

D-Coil is a new digital 3D modeling approach using wax coiling to bring tangibility to the design of digital models. After defining a shape to extrude, the users follow the lead of a hand-held actuated extruder to instantiate the actual extrusion using wax. The tangibility of the wax extrusion sets the stage to create the next components until the digital model is completed.

The digital model affords all digital attributes (ease of transformation, distribution, and 3D printing) while the wax artifact can be discarded or kept as a one-of-a-kind memento.

We present a proof-of-concept implementation of D-Coil and showcase how this additive approach can also be extended to a subtractive process using a digitally actuated cutter. By adding a 6DOF mouse, users can also include scaling, rotation, and bending effects to create a wide variety of shapes often difficult for novices to produce in standard CAD software.

It reminds me of FreeD handheld fabrication tool or Human 3d printer projects.

The FreeD handheld 3d manufacturing device

Innovative handheld 3d milling device. It is held in hand and computer controlled to stop when it reaches the outlines of the 3d object. It looks that the handheld  3d printer is also in making.
