* Nylon 12 White Powder is recommended to print in nitrogen to maintain the most consistent white appearance. Printing in air has been correlated with yellowing of powder over time. Powder yellowing has little to no impact on the ability and efficacy of dyeing printed parts.
** Nylon 11 Powder is recommended to print in nitrogen environment. Printing in air is possible, but will compromise material properties and lead to powder degradation at a faster rate.
