Sedgwick the DLP 3D Printer Hits Kickstarter
If successfully funded on Kickstarter, the Sedgwick could become the most affordable DLP 3D printer on the market (if you don’t count the LittleDLPer – potentially priced at $500 – which has changed its name to the LittlSLA). Currently funded at almost 50% of its $35,000 goal, the Sedgwick uses a projector to throw patterns of light onto layers of UV curable resin. Normally priced far above $1k, DLP machines often boast high resolutions and print speeds. Though the $399 early bird packages for this 3D printer have all sold out, you can still purchase the Sedgwick for upwards of $524.
What differentiates the Sedwick from other DLP machines is that, rather than lifting a print upwards from a vat of resin and working against gravity, it lowers a print layer by layer into the vat. Depending on the size of the vat used, the machine is capable of printing objects of the following dimensions:
- Small vat: 76.8 mm x 76.8 mm x 50 mm / 3 in x 3 in x 2 in.
- Medium vat: 76.8 mm x 76.8 mm x 127 mm / 3 in x 3 in x 5 in.
- Large vat: 102.4 mm x 76.8 mm x 127 mm / 3 in x 4 in x 5 in.
Using any resin designed for DLP or SLA 3D printing, the Sedgwick is capable of 3D printing objects with up to a .1 mm (100 micron) resolution. In this regard, the printer is not quite as capable as other DLP competitors and is more comparable to FFF/FDM machines. The Stalactite DLP printer, which was funded on Indiegogo recently, claims a resolution of 25 microns, while the MakerBot Replicator 2 is capable of layer thicknesses of 100 microns. The print speed of the Sedgwick is about 10-15 seconds per layer with layer thicknesses of .1 mm, resulting in about 20 minutes per cm or 3 cm/hr. This seems to compare to other DLP printers out there, with the Titan 1 (recently funded on Kickstarter) boasting a print speed of about 1.3 inches (3.3 cm) per hour. Quite uniquely, though, the Sedgwick has a built-in desktop to place a laptop to control your printer.
Sedgwick the 3D Printer (not to be confused with Cedric the Entertainer) still looks like quite a capable machine for the price. If you missed the early bird backing, you can purchase a Sedgwick kit (without projector) for $524. Pay $904 and you can buy the kit with the projector. For $1379, you purchase an assembled printer, complete with projector, pushing the Sedgwick closer to the prices of its competitors. Depending on your handiness, the Sedgwick might be a cheap, simple, and quick 3D printer worthy of its low price tag.
