Sedgwick™ is a low cost 3D DLP Printer, perfect for the Hobbyist or Educator.

About this project

Three-dimensional printing is gaining traction in both the business realm and among consumers, but most are still very expensive. Sedgwick™ is a low cost 3D DLP printer, perfect for the hobbyist or educator.

 What can it do? Well, it can do this...

Precision: 0.1 mm (100 micron) resolution in the x, y and z axis.
Print Area: Small & Med Vat with Med Platform.
The included small vat allows for a print area of 76.8 mm x 76.8 mm x 50 mm / 3 in x 3 in x 2 in.
The included medium vat allows for a print area of 76.8 mm x 76.8 mm x 127 mm / 3 in x 3 in x 5 in.
The optional large vat upgrade allows for a print area of 102.4 mm x 76.8 mm x 127 mm / 3 in x 4 in x 5 in.

Resin: Any resin that has been designed for a DLP based SLA printer will work. The number of resins available are quickly increasing. The software is adjustable for the resin's reactivity.

Print Speed:
That depends on the resin, but 10-15 seconds per layer at 0.1 mm per layer is about 20 minutes per cm or about 3 cm per hour.
You simply import a .stl of the object. After scaling and positioning, the model is sliced, creating an image for each layer.

A resin based SLA printer only has one axis that moves, the Z axis. Additionally, the top-down process is mechanically less complex than other bottom-up resin printers. Mechanically speaking, this is a very simple printer.

The Brains - Are you building your own resin printer? Let us help by providing just the brains. You get the PCB, headers, pins, voltage regulator, stepper driver and micro controller.

The Kit - Every part you need to build the printer (Minus the projector). The kit comes with 1 liter resin. Basic tools and supplies are required.

Assembled - The printer is fully assembled, you just need to screw the projector to the frame with the three included screws. The printer comes with 1 liter of resin.

Optional large vat upgrade - This add on comes with a large laser cut aluminum platform, large vat and an extra liter of resin.

With your help, we will be able to:

  • Scale production.
  • Buy in bulk.
  • Create versions that support more projectors.
          

To assemble the kit you will need basic tools and supplies. You should be comfortable using basic tools including sanders, soldering irons, wood clamps, VOM, drills and wire cutters. You will also need supplies like wood glue, epoxy, paint, stain, sealer and solder. You should also be familiar with safety precautions when working with tools, soldering, low voltage, line voltage, epoxy and handling chemicals.

Requirements:
Windows with .Net 4.0
VGA port and the ability to Extend the desktop to the projector.
(Windows 7 Starter does not support extending the desktop)
Input voltage: 110v - 220v (Auto Selected)
DLP Projector (Currently only the Acer X1240 is supported, but plan on adapting the design to support more projectors)
The power cord is NEMA 5-15 to C14. EU/EC/APAC customers will need a converter or new power cord.

When the following levels are met, we will add additional value to your kit by doing some of the most tedious tasks for you.

50+ backers we will orientate, insert and epoxy all the magnets in the kit (There are 12 to hold the lens and platform)

100+ backers we will pre-bend all of the laser cut aluminum platforms (Three bends required for each platform)

200+ backers we will solder the PCBs for you.

After all rewards have been fulfilled, the design files will be released under an open source license.

A very big thank you to Maker Studio at Kansas City's Union Station for assisting us with the video.

Risks and challenges

1. Supply Chain Instability: We plan on maintaining multiple sources for each part.
2. Production Delays: We will do our best to avoid delays, but should they occur, we will keep you updated.
