Abstract
A fused filament fabrication 3D printing method for fabricating an optical article includes applying a surface treatment (1710) to a building plate; heating the building plate to a predetermined plate temperature (1720); dispensing a thermoplastic through a nozzle set at a predetermined nozzle temperature onto the building plate (1730) while translating the nozzle or the building plate according to a first predetermined pattern at a predetermined printing speed to form a first layer; and solidifying the first layer, wherein a range of the predetermined plate temperature is between 30° C. lower than a glass transition temperature of the thermoplastic and 20° C. higher than the glass transition temperature of the thermoplastic, and a range of the predetermined nozzle temperature is at least 100° C. higher than the glass transition temperature of the thermoplastic, and at least 50° C. lower than a degradation temperature of the thermoplastic.
