Sequence Systems is a manufacturing company based in Nottingham, England, GB. They operate FDM machines and offer to print in PLA material in a range of colors. Our test part was printed in Dark Gray PLA. The results fully met our expectations. The part came out smooth and with the required precision. All the surface elements turned out accurate as well. The tricky "bridges" on the top of the model printed out solid with no defective spots. We were pleased with the quality and short turnaround time.
