3D Printing With Wood: Materials and 3D Printers to Use
In the wood 3D printing technique, wood-infused materials are used to produce objects with a striking resemblance to carved wood. In this comprehensive guide, we delve into the intricacies of wood 3D printing, exploring its advantages, limitations, and applications and providing essential tips for achieving optimal results.
Why is Wood Used in 3D Printing?
The primary role of 3D printing with wood lies in the unique aesthetic it imparts to the final products. The wood filament produces prints that closely emulate the grainy finish of pure wood, allowing for the creation of intricate designs and patterns that might be challenging with traditional woodworking methods.
Compared to other composite filaments containing materials like carbon fiber or metal, wood filaments are less abrasive, reducing the likelihood of nozzle damage and minimizing warping or shrinkage.
What is a Wood Filament?
Wood filament, the cornerstone of wood 3D printing, typically comprises 70% PLA (Polylactic Acid) and 30% wood fiber. Unlike its earlier iterations that utilized sawdust, modern wood fiber filaments can produce prints that not only look but also feel and smell like real wood.
With variations ranging from bamboo and birch to cedar and coconut, the choice of wood filament significantly influences the final appearance of the printed object. It is crucial to ensure that the selected filament genuinely incorporates wood fiber rather than just relying on coloring for an authentic finish.
Advantages and Limitations of 3D Printing with Wood
While wood 3D printing brings forth several advantages, including enhanced bonding and the utilization of cost-effective waste materials, it is not without its limitations. Wood prints, mimicking the brittleness of PLA, are inflexible and not recommended for load-bearing applications.
Additionally, the filaments are prone to breakage if not handled with care during the printing process. Moreover, the flammability of wood filaments and their abrasive nature, which can damage brass nozzles, present challenges that must be carefully considered in the printing environment.
How to Use Wood in 3D Printing?
To achieve optimal results in wood 3D printing, certain considerations must be taken into account. Wood filament, with its lower adhesion compared to PLA, requires the use of print adhesives like tape, gluesticks, or hairspray on an unheated build plate. The choice of nozzle diameter and material is crucial, with hardened steel nozzles recommended to prevent damage. Moisture sensitivity is another factor to address, as wood filament readily absorbs moisture. Proper storage in an airtight container and pre-drying before use can mitigate this issue. Post-processing techniques such as sanding or polishing offer avenues for refining the final appearance of wood prints.
What Are the Best Configuration Settings for Wood 3D Printing?
1. Temperature Settings
The Hot End
Similar to regular PLA, preheating the printer's hot end is essential when working with wood filament. Ideally, maintain a temperature range between 170 and 220 ºC, though the exact temperature may vary depending on the specific filament. What makes wood filament intriguing is the ability to experiment with temperatures, influencing the color and finish of the print. Higher temperatures result in darker shades, creating an authentic wood grain pattern.
However, it's crucial to be cautious as wood is flammable. Excessive heat, coupled with slow filament extrusion, can lead to damage or even fire. Stay within the recommended temperature range provided by the manufacturer to ensure safety. To prevent clogging, use a nozzle larger than the standard 0.4 mm and keep it clean.
The Print Bed
While a heated bed is not mandatory for wood filament, using one can enhance print quality. If available, preheat the bed to a range of 50 to 70 ºC. Achieving adhesion is critical as wood filament tends to cause parts to slide during printing. Painter's tape, glue sticks, glass beds, or PEI sheets are effective adhesive surfaces to secure prints.
2. Print Speed Range
When working with wood filaments, finding the optimal print speed is crucial for achieving the best results. The recommended speed typically falls within the range of 40-75 mm/s. It is advisable to start at the lower end of the spectrum and gradually increase the speed. Wood filaments exhibit excellent layer adhesion, allowing for the possibility of printing at higher speeds. This enhanced layer adhesion not only contributes to overall print strength but also minimizes visible layer lines, resulting in a smoother finish.
3. Layer Adhesion and Strength
The inherent good layer adhesion of wood filaments plays a vital role in the strength of the final print. Improved interlayer bonding, attributed to the added wood particles in PLA, enhances the structural integrity of the printed object. This characteristic allows for the production of prints with larger layer heights without compromising aesthetics or the overall quality of the final product. The ability to print at higher speeds while maintaining excellent layer adhesion is a notable advantage of wood 3D printing.
