Riverhead Books partnered with MakerBot to make the first 3D-printed book slipcover for Chang-rae Lee’s On Such a Full Sea. The book fits into the off-white slipcover, which features the letters of the title rising off its surface at an angle. At first it took almost 30 hours to print each slipcover, but after fine-turning the process, theyre able to get the final slipcovers made in 15 hours. No matter how laborious the process, well be seeing more of this experimentation in the publishing industry.
