To improve the dimensional accuracy of 3D printed parts produced by vat photopolymerization, a controlled light penetration through the photopolymer resin is necessary to avoid excessive unwanted curing caused by overexposure. Although photoabsorbing additives like Sudan I can attenuate light to dec...
