This week’s selection is the amazing life size body print made by Matty Benedetto.
Benedetto operates the Unnecessary Inventions YouTube channel, where he designs “unnecessary consumer products” in each video. He puts out several per week, which demonstrates his creativity and energy.
One of his most recent “inventions” was a life size 3D print of himself — that talks. This was published in his video, “I 3D Printed Myself To Do This One Task For Me”.
The assignment was to welcome individuals at the entrance of his workshop.
Benedetto already possessed a 3D scan of himself, facilitating the procedure significantly. Nonetheless, he (and probably no one else) owns a 3D printer that’s large enough to fabricate a copies size of a person in a single operation.
The challenge was then to divide the 3D model into bits that could be printed. These components would then be printed individually, and later assembled to create a complete human figure.

One of the issues that came up was sizing: could he ensure that the 3D print would match his actual height once it was put together? To confirm this, Benedetto began by printing a foot to compare with his own. After this step was successful, he proceeded to print out an entire leg. As this came out in the correct proportions, Benedetto felt confident to go on with creating the remaining parts.
However, there were tens of pieces that were needed. This meant that he had to make full use of his print farm, which seemingly included many devices and models from various brands like Bambu Lab. Carrying out the operation in parallel considerably cut down the total time taken to finish the project.
Benedetto’s printed replica turned out to be the right height upon assembling all the pieces, albeit being made of a variety of filament colours.
The final step was fitting the device with a motion sensor. This was programmed to initiate an embedded board in order to execute an audio file as a form of greeting for those who walk by.
Intriguingly, Benedetto did not pen the programming for this step. He requested ChatGPT to create the code, and it was reportedly successful. This information is particularly beneficial for individuals embarking on 3D printed ventures that include electronics.
The versatility of desktop 3D printers is further exemplified by this project, as it proves the potential of these machines to manufacture large objects, given the willingness to piece them together.
Therefore, in response to the query, “how big can it print”, the answer is indeed “any size”.
