I am exploring the area of 4D printing and trying to decide which printer to buy. I would like to print structures made of shape memory polymers (SMP). Since there are various printers from several companies, I am looking for a feedback from someone who already used these printers.
For thermal reactive SMPs: FDM, stereolithography, and Polyjet. FDM would be the cheapest option. For moisture reactive, Polyjet and extrusion-based printers. Polyjet is probably the most expensive option.
Thank you so much Steven K Leist for your comment. I see that you used Tissue Scribe and FDM Flashforge Creator Pro Dual Extrusion printers. Have you used any other printers?
Just those devices for the 4D printing purposes, but many others for 3D printing. I believe most 4D printing research uses the polyjet printers. Skylar Tibbits, Jerry Qi, and Qi Ge all used the polyjet for their research. Marwan Nafea
Dustin Ahrendt may I know how do you select the SMP material for 4D Printing? Thank you.
I would say a SEAM-HEX working with pellets is a very good solution for this ;)
