Get outstanding 3D printing results when you use 1.75mm PLA Plus+ 3D Printer Filament from Monoprice! PLA Plus+ is a good choice for a printing material if you are looking for high accuracy and high resolution. It does not require a heated base and has a very low shrinkage rate (0.3%). PLA Plus+ is stronger than ordinary PLA; possessing the same strength as normal ABS material. This 1.0kg spool features a thickness of 1.75mm ±0.10mm; with a roundness variation of only 0.03mm. It has a nominal processing temperature range of 205 ~ 225°C (401 ~ 437°F). Thickness and roundness factors are laser measured at the factory to ensure accuracy over the entire length of the filament. The negatives of using PLA Plus+ is that it is vulnerable to degradation from moisture; sunlight; and heat. Additionally; it is more prone to overheating during processing; which can cause dripping and drooping if it gets too hot. Support Files: Filament Comparison Chart (180416)
