IP-DIP: IP-Dip is a liquid negative-tone 2PP resin formulation by NanoScribe designed for printing the finest possible features. IP-Dip is a component of the 3D SF Solution Set. Tall structures exceeding the working distance of the objective can be printed using the DiLL configuration. IP-S: IP-S is a highly viscous liquid negative-tone 2PP resin formulation by NanoScribe designed for printing medium-sized features in DiLL. IP-S combines low shrinkage and high stability with a smooth structural surface finish perfect for micro-optics. The photosensitivity is tailored for two-photon polymerization and UV-curing is also possible. As a component of the 3D MF solution set, IP-S is suitable for printing structures with dimensions of several cubic millimeters. IP-L 780: IP-L 780 is a liquid negative-tone 2PP resin formulation designed for printing small features in oil immersion configuration. IP-L 780 combines high resolution with low shrinkage and high stability. IP-Q: IP-Q is a highly viscous liquid negative-tone 2PP resin formulation by NanoScribe. The 3D LF Microfabrication Solution Set, including IP-Q, extends 2PP 3D printing towards rapid printing of mesoscale structures with millimeter sizes, micrometer precision, and maximum throughput up to the macroscale. SU-8: SU-8 is a UV-curable negative-tone 2PP resin by Kayaku Advanced Materials. This resin is well-known and widely used in the lithography community. [The following article applies only to SU-8 100 determined to be the most suitable resin for 2PP as it balances quality and printing speed.]

Advanced Printing Procedures

Parameter Sweeps

While the default DeScribe settings work in many cases, high precision parts may require careful tailoring of the printing parameters, such as laser scan speed, laser power, hatching distance, among others. The quickest way to test a variety of these parameters is with the Advanced STL Processing tool in DeScribe. Using a test STL, usually a small part or feature, one can generate a 1D or 2D array of parts with parameters varied between a start and end point. The image below illustrates a 4x4 array which varies scan speed and hatching distance, which impacts effective laser dose and can highlight issues due to proximity effect:

GWL Programming

Advanced printing procedures often require modification to the basic files generated by the DeScribe slicer. In addition to offering much greater control over your print, a user can stitch together multiple jobs into a single part with differing print modes, or even objectives. Many of the most useful commands are highlighted in the sections below. A full reference list is available on Nanoguide and in the DeScribe editor under Window → Command Reference.
