Combating waste wooden’s environmental influence, Mexico-based firm MANUFACTURA in partnership with La Metropolitana, a furnishings manufacturing and design workshop has led an initiative named “The Wooden Challenge” or “UN PROYECTO DE MADERA.”
MANUFACTURA highlights The Wooden Challenge’s basis lies within the strategies grounded in wooden’s inherent traits. This initiative addresses La Metropolitana’s every day manufacturing of 5-6 luggage of sawdust, weighing 40 kg every. Envisioning a round financial system, this undertaking repurposes these waste byproducts to craft 3D printed constructions by way of a robotic arm, minimizing waste and environmental influence, and embracing a sustainable cycle.
What’s the end result of this undertaking?
Using an extruder mounted on a KUKA KR-150 industrial robotic arm, the 3D printing course of employs exact instructions to deposit materials, yielding complicated, environment friendly, and sustainable constructions. The fabric’s demonstrator focuses on three architectonic-scale partition partitions, comprising 72 items measuring 20 x 20 cm. This fabrication occurred over a three-week interval, encompassing each the 3D printing and drying levels.
The items simply replicate and assemble, permitting easy component scaling. These bricks are sustainably produced in a round method, using waste-sourced uncooked supplies from La Metropolitana, processed for optimum sizing. Most sawdust is wealthy in cellulose, hemicellulose, lignin, and different substances fascinating in industrial purposes. Moreover, ensuing elements show exceptional lightness; every brick averages 207 grams, totaling 15 kg for all the construction, says the corporate.
Collaborating with Mexico’s Autonomous Nationwide College (UNAM), the Laboratory of Supplies and Structural Techniques (LMSE) is actively engaged in materials evaluation. By way of microscopic inspections and compressive checks, the fabric has been rigorously assessed. Underneath compression, the fabric’s restricted flexibility led to pre-fracture failure because of defragmentation. Regardless of this, it demonstrated a median resistance of 836.5 kg and a most common resistance of 20.15 kgf/cm². These values are on par with fired clay bricks, which generally present resistances starting from 13.34 to 39.50 kgf/cm². Additional exploration and refinement are crucial to completely uncover the fabric’s properties and sensible potential.

A sustainable answer to Mexico’s waste downside
Central to the undertaking is the creation of a bio-composite centered on sawdust, primarily sourced from Mexico’s native Tzalam tree species. Tzalam wooden, identified for its look and excessive hardness, blends with natural binders and lime to kind a humidity and fungal-resistant matrix. After thorough experimentation, it was decided that sawdust from particular machines, comparable to calibrating machines and CNC routers, exhibited optimum bodily properties for 3D printing, says MANUFACTURA.
MANUFACTURA studies that Mexico faces a every day problem with round 102,895 tons of generated waste. The Surroundings and Pure Sources Division signifies that solely 9.63% of this waste is presently recycled, whereas a big 83.93% is deposited in last disposal websites, contributing to air pollution and environmental hazards. Concurrently, Mexico’s annual timber manufacturing reaches about 9 million cubic meters. Sadly, a considerable portion of this timber, particularly 45 to 65%, culminates as waste byproducts like sawdust, shavings, and bark, with minimal financial worth.
With this in thoughts, The Wooden Challenge’s goals give attention to revamping sustainability and development strategies. It includes extracting uncooked supplies from varied industries, creating biodegradable supplies, and using cutting-edge know-how for environment friendly fabrication. This method goals to show waste into invaluable assets, fostering sustainability and creating job alternatives.

Developments in wooden 3D printing
Hebrew College of Jerusalem researchers developed a wood-based 3D printing materials that transforms into predetermined shapes. Comprising wooden flour and plant extracts, the eco-friendly materials warps because it dries because of fiber orientations. Although developed earlier, this materials permits managed moisture evaporation throughout deposition, permitting the fabric to kind complicated objects.
Researchers from the Massachusetts Institute of Know-how (MIT) and the Charles Stark Draper Laboratory addressed deforestation by creating a technique of 3D bioprinting wood-like supplies. Leveraging dwelling cells from Zinnia elegans crops, the tactic creates wood-like supplies, probably reshaping the manufacturing of customized shapes like furnishings with out tree consumption. Nice-tuning construction properties, comparable to density and stiffness, was achieved by adjusting progress chemical substances. This innovation showcased how sustainability and design may intersect, marking a big development in eco-conscious manufacturing.
