Continuous and peaking at a particular wavelength, a blackbody's spectrum is continuous. For more intensely heated objects, the apex of the black - body curve shifts to shorter wavelengths.
How much are filament temperatures?
The ideal printing temperature for PLA filament settings typically ranges between 185 and 205 degrees Celsius. Your ideal print would be nearer the low end of the scale of this PLA thread temperature range if you use 1.75mm rather than 2.85mm (or 3.00mm).
Generally speaking, PLA prints between 190°C and 220°C at the a relatively low temperature. Depending on the printer you're using and, more significantly, on the brand of filament you're using, a Pva filament's ideal manufacturing temperature will vary.
