*Philip J. Kitson, Stefan Glatzel, Wei Chen, Chang-Gen Lin, Yu-Fei Song,and Leroy Cronin: [ 3D printing of versatile reactionware for chemical synthesis], Nat. Protocols, 2016, 11 (5), 920-936
**Describes the steps for making 3D printed reactionware
**Open-source type development driving the growth of 3D printing
**Advantages of 3D printing in chemistry: topology, geometry and composition of reactors precisely controlled
**The versatility of 3DP materials is an advantage, but all of their applications impossible to describe in a single document
**Extrusion-based methods (FFF/FDM) popular and economical, PLA and ABS most common materials
**FDM applied in making fluidic reactors, but for the most part research focused on 3D printable materials, post-treatments, and batteries and LEDs
**Limitations: epoxy- and acrylate-based materials used in SL not resistant organic solvents or extreme pHs. Similar problems for PLA and ABS.
**FFF/FDM of nylon and PP more promising for chemical applications
**Perfluorinated polymers difficult to print (small temperature window) and toxic.
**Conventional FFF/FDM materials suitable for biological labware (water solutions, mild pH)
**Choosing a material: inert to the desired chemistry. The author's choice: PP. Easy to print, good resolution and chemically inert.
**PP attacked by very strong oxidizers, also by heated solvents (toluene)
**Different grades of PP require different print settings (different melt profiles and flow)
