I'm looking to place an order for black filament for 3D printing. Specifically, I would like to purchase 50 rolls of filament, ensuring that the quality is suitable for high-resolution printing. Please provide details about the available options, including the diameter and any variations in material composition. Additionally, I'm interested in acquiring 2 3D printers to complement my production needs. It would be great if you could send me information on the models you have available, along with their specifications and pricing. I'm eager to understand the lead time for delivery as well. Your prompt response would be appreciated!
