Drawbacks of using 3D printing materials
While 3D printing is a breakthrough technology, it also has its fair share of drawbacks, particularly when it comes to the materials used for printing. Here are the top four drawbacks to keep in mind:
- Material limitations: While there are many materials that can be used for 3D printing, most printers can only handle a few types of materials at a time. This means that if you want to print an object using a specific material, you’ll need to make sure that your printer can work with that material.
- Cost: 3D printing materials can be expensive, especially if you’re using high-quality materials. This is particularly true if you’re using a lot of material, as the cost can quickly add up. While there are cheaper materials available, they may not offer the same level of quality as more expensive materials.
- Quality issues: Depending on the material you’re using, you may encounter quality issues when 3D printing. Some materials are prone to warping or cracking, while others may not fully adhere to the build platform, leading to a failed print. This can be frustrating, especially if you’ve invested a lot of time and money into a project.
- Safety concerns: Finally, it’s important to note that some 3D printing materials can be hazardous if not handled properly. For instance, ABS plastic emits fumes that can cause eye and throat irritation, as well as headaches and dizziness. Other materials, such as nylon, can release toxic fumes when heated.
The future of 3D printing materials
Despite these drawbacks, 3D printing continues to reinvent manufacturing processes across industries. And, with advancements in materials science, we may see new materials developed that address these issues. Researchers are currently exploring the use of bio-based materials, such as algae and mushrooms, that are eco-friendly, sustainable, and biodegradable.

Recycling and sustainability of 3D printing materials
3D printing has been praised for its ability to create highly customized products, cutting down on material waste. However, it’s important to note the sustainability and recycling of the materials used in 3D printing.
- PLA: One of the most commonly used materials in 3D printers is PLA (polylactic acid), which is made from renewable sources like cornstarch and sugarcane. It’s also biodegradable, which makes it a sustainable option. However, proper disposal is important, as it won’t decompose if incinerated.
- ABS: Acrylonitrile butadiene styrene (ABS) is one of the most popular materials used in 3D printing, but it’s not biodegradable and is made from non-renewable petrochemicals. However, it’s possible to recycle ABS by collecting pieces of unused filament and melting them down to be used again.
- TPU & TPE: Thermoplastic polyurethane (TPU) and thermoplastic elastomer (TPE) are flexible 3D printing materials that can be recycled, but it’s important to separate them from other plastics during recycling.
It’s also important to note that 3D printing produces a lot of waste in the form of support structures and failed prints. Some companies have implemented recycling programs, allowing customers to send back unused or failed prints to be recycled into new material. Additionally, some companies have started using recycled plastic in their 3D printing materials, reducing the need for new materials.
In terms of sustainability, 3D printing has the potential to reduce waste and carbon emissions by creating custom products on-demand, rather than relying on mass production and transportation of products. However, the sustainability of 3D printing ultimately depends on the materials used and the responsible disposal and recycling of those materials.
