How To Choose Between Polycarbonate And PLA?

Strength Requirements：If your parts need to withstand high strength, high impact or high pressure, then PC is a better choice. PC’s high strength and rigidity allow it to withstand these stresses, and its chemical and abrasion resistance also allow it to perform well in harsh environmental conditions.
Cost Matters：If price is your main consideration, PLA may be a better choice. PLA generally has lower material costs than PC and is easier to print, which means you may not need to invest as much time and resources in adjusting print settings or troubleshooting print problems.
Printing Technology：If you are new to 3D printing or don’t have much printing experience, PLA may be a better choice. PLA is simpler to print and typically does not require a heated bed or special print setup, making it a good choice for beginners.
Application Scenarios：Finally, you need to choose the most appropriate material based on the specific use of the part. If the part must be used in harsh environmental conditions, or needs to withstand high pressure or friction, PC may be a better choice. If the part is intended primarily for education, art, and decoration, or if rapid prototyping is required, PLA may be a better choice. https://www.lsrpf.com/
