The Marine Industry is perfect to take advantage of all the benefits of high end production level 3d printing. No need to create molds. Instant design modification allows your parts to be installed into your boats sooner, being more cost effective and with less engineering time. Mistakes from failed design considerations are easily corrected allowing the newly modified part to be available for installation in only a day or two. Embedding materials within 3d printed materials such as stainless steel hardware makes 3d printing the most versatile manufacturing process available. CNC mills have their place but can never offer all that 3d printing can.
