One of the rader 3D printing gadgets to come along in the last few years is the handheld 3D printing device pen that allows for users to freehand 3D objects via plastic filament. Unfortunately, you really are going to require to be a little artistic in order to in fact be able-bodied to print a thing that does not appear like a clump of melted plastic, that frequently manufactures the learning curve really steep. Whilst the manufacturers sell things like templates and how-to guides, it’s yet tough to manufacture anything significant without a lot of practice and trial and error. The 3D printing pens are yet a lot of fun to play around with, but ultimately they can be a little frustrating and seem additional like a novelty than a useful tool.

Whilst the actual point of the 3D printing pen is to be a freehand 3D printing device, it mayn’t injure to get a little bit of assist while via it. And that is precisely what Yeliz Karadayi’s “Guided Hand” thesis project aims to do. The device is all but a 3D printing pen attached to one of those haptic interface robotic arms that can manufacture certain that users 3D print familiar-bodied shapes, while yet contributeing the freehand feeling and appear of a handheld 3D printing pen. But beyond that, the Guided Hand 3D printing device in fact gives users really a few options of use that can take this of a novelty to a useful turn it into tool.

The Geomagic Touch haptic device that Karadayi utilized for the Guided Hand 3D printing device is fundamentally a robotic arm that is primarily utilized as a 3D turn it into or sculpting tool. It has a variety of settings that allow it to be utilized really variously depending on what the user is doing. It can provide resistance, as if the user was sculpting virtual clay, or allow for freehand 3D sketching. The Geomagic Touch is a excellent digital turn it into tool, but when attached to a 3D printing pen it uses the same innovation to become a thing really various, and really kind of awe-inspiring.3dp_guidedhands_rabbit

Whilst attached to a 3D printing pen, the haptic arm manufactures certain that users are printing within the lines, so to speak. The arm provides the user with resistance while printing a turn it into, and contributes several options to assist turn it into a few truly one-of-a-kind 3D printed objects. Primarily it can be set to containment mode, that provides the user with an invisible set of boundaries that prevent the pen of moving outside of them. It can in addition be set to boundary exclusion mode, that prevents the within of the version of being printed, while enabling the outside to be created up around it. There is in addition an attraction mode that can contribute the users guided aid while tracing a turn it into within 3D space.

The Guided Hand 3D printing device in addition can be set to create several various types of textures and influence. The pen can be set to vibrate so the plastic lines are additional squiggly, or it can be set to assist the user create specific patterns, much like to a filagree or a beaded effect. The device can in addition be set to only provide a tiny amount of resistance so users aren’t completely restrained of changing the 3D version or experimenting with textures. All of these tools allow the Guided Hand to be utilized to turn it into 3D printed sketches, so artists and turn it intoers can explore creating objects in 3D space in real time.

You can see a few video of the Guided Hand 3D printing device here:

Whilst this is only a prototype at the moment and there does not seem to be any plans to sell it, it is yet a really rad project that I may see having a lot of applications beyond only being a fun novelty. Design meetings can see ideas roughly 3D printed out while the entire turn it into team watches, only to see how the object can exist in 3D space. It may in addition convert digital drawings into 3D versions that can be traced or printed. You can read Yeliz Karadayi’s entire thesis paper and see tons of images and printed samples here, and you can learn additional of the Geomagic Touch haptic device here.
