DIY Wooden 3D Printer Project Build

This Maker Spent Six Months Building a 3D Printer Out of Wood

By

DIY Wooden 3D Printer Project Build
Mitsu Makes spent six months on one of the more unusual 3D printer projects in recent memory. The result stands as a working machine with a frame constructed primarily from wood rather than the aluminum or steel common in most DIY and commercial designs. An interest in exploring alternative materials drove the effort. Standard builds lean heavily on rigid metals to maintain alignment under the forces of rapid movement and heating cycles. This project tested whether careful design and added supports could let wood succeed in the same role.

Ivan Miranda Marble Clock 3D-Printed Seconds

Custom-Built Marble Clock Uses Black and White Marbles to Rebuild the Time Every Single Second

By

Ivan Miranda Marble Clock 3D-Printed Seconds
Ivan Miranda has turned a long-running experiment with rolling balls into a clock that actually keeps pace with passing seconds. The latest version of his marble timepiece refreshes its display fast enough to show hours, minutes, and seconds without any visible lag between changes. Each digit takes shape inside a compact 3-by-5 grid. Fifteen marbles settle into the exact spots needed to outline a number. White marbles stand where a digit needs its bright segments, while black marbles fill the remaining positions to create clear contrast. The result looks like a physical version of familiar numeric shapes, built from actual objects rather than light or ink.

Plurial Novilia PERI 3D Construction Europe Largest 3D-Printed Apartment Building

France Printed This Apartment Building Layer by Layer and Finished It Three Months Early

By

Plurial Novilia PERI 3D Construction Europe Largest 3D-Printed Apartment Building
Plurial Novilia handed over ViliaSprint² in Bezannes, France, after crews completed the full structure in noticeably less time than a matching conventional building right next door. The project delivers 12 social housing apartments across three floors and 800 square meters of living space. Each unit opens onto its own timber balcony. A gently curved outer wall and rounded floor plan give the building its shape without the usual extra cost that custom molds would demand on a standard job.

Hugging Face Releases a $2,500 Humanoid Robot That Anyone Can Print and Teach to Stand

By

Hugging Face LeRobot Humanoid Open-Source Robot
Hugging Face has shared complete plans for a bipedal robot platform that costs roughly $2,500 in parts and relies mostly on 3D-printed pieces plus common actuators and electronics. Builders start with 75 printable files that form the torso along with left and right legs. The design breaks into modular sections including hip mechanisms, thighs, knees, shins, ankles, and feet. A public Onshape CAD model lets anyone inspect or adapt the geometry before printing.

3D-Printed Water-Cooled Rocket engine Project Build

One Builder’s Quest to Keep a 3D Printed Rocket Engine from Melting Involves Water

By

3D-Printed Water-Cooled Rocket engine Project Build
Mr. More Gooder spends his time in the workshop turning everyday ideas into hands-on experiments. This time he decided to tackle a stubborn problem with rocket engines built on standard FDM 3D printers. Plastic parts usually fail quickly once the fuel ignites because the heat softens and melts the material. He came up with a direct fix by routing water through channels inside the printed walls to carry the heat away before the plastic could give way.

Founders Inc’s Polysynth P1 Could be the First Production Multimaterial 3D Printer

By

Founders Inc. Polysynth P1 Multimaterial 3D Printer
Resin 3D printers have stuck to a single material through every layer for years because switching resins always brought contamination and extra cleanup. Eric Potempa watched that limitation long enough to do something about it. He founded Polysynth in 2025 with backing from Founders Inc and created the P1, a machine that brings up to eight different resins into the same print job without stopping for manual intervention.

MIT Y-Zipper Three Sides 3D-Printing Robotics

Innovative Y-Zipper With Three Sides Just Solved a Decades-Old Puzzle in Robotics

By

MIT Y-Zipper Three Sides 3D-Printing Robotics
Researchers at MIT reached back to 1985 and pulled an old design out of storage. What they built with 3D printers now turns three floppy plastic strips into a solid beam in seconds. The device carries a simple name: the Y-zipper. Its triangular profile locks parts together so tightly that soft tentacles become load-bearing supports. Engineers can print the whole assembly in ordinary plastic and watch it switch states on command.

Homemade DIY Billet Aluminum Two-Stroke Engine

Auto Enthusiast Carves Functional Two-Stroke Engine from Solid Metal

Homemade DIY Billet Aluminum Two-Stroke Engine
Camden Bowen has spent years chasing the perfect two-stroke engine built entirely from scratch. His earlier versions came from a 3D printer and then from parts picked up at the hardware store. Each one taught him something new about what works and what falls short under real fire. For his latest project he set a higher bar and machined the whole thing from billet aluminum on a basic mill and lathe.

3D-Printed Electric Turbofan Model

Build an Electric Turbofan Model That Reverses Thrust With a Simple 3D Printer

By

3D-Printed Electric Turbofan Model
CADLY poured months of design effort into creating an electric turbofan model that anyone can produce at home. Files sit ready for download from the maker’s own site or the Printables page, and a standard 3D printer handles every major piece. The finished unit draws direct inspiration from the CFM56 engines found on Airbus A320 airliners, yet it runs on basic electronics and a small motor instead of jet fuel.
