How to Make 3D Printing More Energy Efficient

Cutting back on energy use is a critical step toward creating greener, more sustainable 3D printing practices. By fine-tuning print settings, upgrading hardware, and making smarter production choices, it’s possible to significantly lower energy consumption without sacrificing quality. Here’s a closer look at where energy is often wasted and how targeted changes can make a difference.

Ways to Save Energy in 3D Printing

Heated components, like the heated bed and extruder, are the biggest energy guzzlers in most 3D printers. In fact, they account for about 72.9% of a printer’s total power consumption.

One effective solution is upgrading insulation. Research conducted in April 2023 on Ender series 3D printers from Shenzhen Creality 3D Technology Co. found that insulating heated components and refining extruder setups could slash energy use by up to 38%. Even better, these changes also reduced material usage by over 55%.

Adjusting print settings is another straightforward way to save power. For non-structural parts, reducing infill density to 20% and increasing layer thickness can shorten print times and lower energy use . Additionally, opting for PLA over ABS helps, as PLA doesn’t require the high bed temperatures that ABS does. Switching to lightning infill instead of traditional support structures can cut material use by up to 51%, and reducing support line widths from 0.6 mm to 0.4 mm can save around 31–32% of material.

The type of 3D printing technology you use also plays a role in energy consumption. Here’s a quick comparison:

FDM printers are generally more energy-efficient compared to SLA, while DED and SLS printers tend to consume the most power.

Simple habits can also make a big difference. Keep the printer door closed during operation and enable auto energy-saving modes to cut down on idle energy waste. For industrial printers, turning off the bed vacuum system after printing is complete can prevent unnecessary power draw.

"When you design a 3D printed part, consider how that design will impact the overall print time… Leveraging 3D printing’s design freedom to consider various options can positively affect how much energy the printer uses." – Stratasys

Benefits of Local 3D Printing Production

Beyond printer-specific adjustments, local production can further enhance energy efficiency by eliminating the need for long-haul transportation. Transportation emissions are a major environmental challenge, with the sector contributing about 2.5% of global carbon emissions.

By enabling production closer to the point of use, 3D printing significantly reduces transportation-related emissions and packaging waste. Instead of shipping physical products, companies can distribute digital files and print items locally.

Authentica’s platform has shown just how effective this approach can be, achieving a 40% reduction in CO₂ emissions across land, sea, and air logistics, and cutting overall transportation needs by 90%. For example, a major automotive supplier in Australia reduced lead times by 97% and slashed transportation requirements by 90% using this model. Similarly, Toyota Angola now prints spare parts directly at dealerships, cutting wait times from six months to under 72 hours. John Deere has also adopted a distributed manufacturing system, allowing local sites to download designs and print products on demand, which reduces both material waste and shipping distances.

Local production doesn’t just benefit the environment – it also boosts local economies by creating well-paying jobs, decreasing reliance on overseas manufacturing, and encouraging innovation. Plus, it strengthens resilience against supply chain disruptions, as demonstrated during recent global shipping challenges.

"3D printing technology is set to transform the traditional supply chain model as we know it. It could potentially allow parts to be produced at the point and time of use rather than manufactured and shipped in advance." – Professor Jan Godsell, WMG at the University of Warwick

This shift toward localized production isn’t just about saving energy; it’s about rethinking how products move from design to consumer. The result? A more efficient, environmentally conscious manufacturing system.

Eco-Friendly Materials for 3D Printing

Choosing eco-friendly materials is a smart step toward making 3D printing more sustainable. While traditional plastics have been the go-to for years, new materials sourced from renewable resources like corn starch, algae, or wood fibers are making waves. These alternatives not only reduce environmental harm but can also be cost-effective. Understanding what makes these materials environmentally friendly and how they perform is key to making smart choices.

What Makes 3D Printing Materials Eco-Friendly

Eco-friendly 3D printing materials are designed with sustainability in mind. They align with principles like using renewable resources, promoting recyclability, and minimizing environmental harm.

Several factors make a material environmentally friendly. First, its origin matters – a bio-based source, such as corn starch or algae, is far better than petroleum-based plastics. Recyclability is another big factor; materials that can be reused without losing quality are a win for both the planet and your wallet.

Compostability is also a game-changer. Materials that break down naturally or in industrial composting facilities eliminate long-term waste. Safe handling and disposal further ensure they don’t harm users or the environment.

Transparency in sourcing adds credibility. Materials with traceable supply chains and low-impact production processes give users confidence in their sustainability.

Interestingly, improving material reuse rates can significantly cut down on waste. For instance, increasing the reuse rate of powder from 50% to 80% can shrink a printed part’s carbon footprint by 70%. Plus, recycled materials already make up as much as 95% of some 3D printing inputs, and projections suggest that 40–60% of printed items could be recycled.

These criteria set the foundation for exploring the growing range of sustainable materials.

Types of Green 3D Printing Materials

The world of eco-friendly 3D printing materials is expanding rapidly, offering options for nearly every application. Each material has its strengths and limitations when it comes to performance and environmental impact.

PLA (Polylactic Acid) is a standout in the bio-based category. Made from renewable resources like corn starch, it prints at lower temperatures, produces fewer emissions, and is biodegradable under industrial composting conditions. However, it isn’t as durable or heat-resistant as petroleum-based plastics.

Recycled PETG strikes a balance between sustainability and performance. It offers better mechanical properties than PLA while reducing the need for new plastic. Using recycled PETG can lower carbon emissions by 30–80% compared to virgin materials. Filamentive, for example, produces recycled PETG from pre-consumer waste, including discarded plastics from manufacturers.

Plant-based polymers like PA11 are premium options that boast a smaller carbon footprint compared to fossil-based materials. Nylon PA12, for instance, has achieved a 49% reduction in its carbon footprint thanks to renewable energy in production.

Recycled specialty materials tackle specific environmental issues. Fishy Filaments, for example, creates 3D printer filaments from recycled fishing nets, addressing ocean plastic pollution directly.

TPU (Thermoplastic Polyurethane) is another eco-friendly option. Its low energy consumption during printing, combined with its flexibility and durability, helps extend product life and reduce waste.

Here’s a quick comparison of popular materials:

Bio-composites, which mix natural fibers like wood or hemp with polymers, are another interesting option. While they might not always biodegrade fully, they reduce the overall use of synthetic materials, making them a more sustainable choice.

Cost is also becoming less of a barrier. Recycled filaments are often cheaper than their virgin counterparts. Plus, additive manufacturing could reduce raw material needs by up to 90% by 2050, according to the European Commission. For instance, recycled HDPE filament production uses only 38.29 MJ/kg of energy compared to 79.67 MJ/kg for virgin HDPE.

These materials are already proving their worth in real-world applications. From biodegradable medical implants to recycled automotive prototypes and sustainable consumer products, the possibilities are growing. Companies like Markforged and Greentown Labs are driving innovation in this space, while new materials like algae-based filaments and carbon-neutral polymers continue to emerge.

The key to success lies in matching the material to the application and fine-tuning printer settings to get the best results. This ensures that sustainability goals don’t come at the cost of performance.
