The Costs of 3D Printing Materials: PLA, Polycarbonate, and ASA Prices Explained

When it comes to 3D printing, the cost of materials can play a significant role in the overall expenses. Understanding the different types of materials and their respective costs is crucial for both hobbyists and professionals.

1. Normal PLA and Its Pricing

Normal PLA is commonly used in 3D printing and can range from 20 to 40 per kilogram. This provides a good balance between cost and quality. However, there are variations like 16th PLA and budget PLA that can offer slightly different prices and performance.

2. More Expensive Materials: Polycarbonate and ASA

For materials like Polycarbonate or ABS (Acrylonitrile Butadiene Styrene) added to Polycarbonate (ASA), the price increases substantially. These materials are more durable and resistant to heat and chemicals, but they come at a higher cost. A kilogram of Polycarbonate or ASA typically costs 40 per kilogram or more.

3. Fused Filament Fabrication (FFF) Material Pricing

FFF materials are sold by weight, usually in the form of a 1 kilogram roll. For example, a 1 kilogram roll of 1.75 mm natural colored PLA costs approximately $29. This pricing reflects the quality and ease of use of these materials.

4. Time as a Major Cost Factor

While material costs are important, it is often the time required to print that can be the most significant cost factor. Most 3D printing technologies, including FFF, work by layering materials one on top of the other, which inherently makes the process time-consuming. Additionally, the initial investment in 3D printers and maintenance can add to the overall costs.

5. DIY Approach and Cost Management

For those looking to reduce costs, a DIY approach can be highly effective. For instance, using a machine like the FIlabot, you can melt PLA pellets into filament, thereby reducing the cost from as high as 20 per kilogram to approximately 10 per kilogram. This can be a significant saving for hobbyists and small-scale manufacturers.

6. Professional Experience and Brand Dependence

Using a professional 3D printer like the MakerBot in a classroom or professional setting, the cost of materials can be higher. I have firsthand experience with the MakerBot in my classroom, and while I have found discount materials, they have often led to issues. The average cost of one spool is around $60, which can vary based on the project requirements. Details like the amount of fill used in the project can significantly impact the number of projects you can produce per spool.

In conclusion, the cost of 3D printing materials is a combination of upfront material costs and the time required for printing. By understanding the differences and using cost-effective methods, you can maximize your efficiency and reduce overall expenses.

Hope this helps!
