Maureen is an open source SLA printer based off of commodity DLPs.

TODO list

Here is a list of important stuff that needs to be done, anyone can do this if you are reading this you can do it. Jump in!

TODO [ ]: Draw and layout PCB UNO shield

TODO [ ]: get parts list for Z-stage from here and add to BOM.

TODO [ ]: build Z-stage, take pictures and write up documentation

TODO [ ]: Create a first pass of CAD files for support structure: something to mount the DLP to and something to hold the vat.

TODO [ ]: write up how to modify DLP for this project

TODO [ ]: research/write up software stack

There is a an awesome version of such a printer at B9Creator. The plans for this have not yet been released.

You can also join the #lemoncurry chat on IRC for pressing questions.

A very active group discussing the printers can be found here

Some theoretical documentation and lots of links can be found at Lemoncurry.

Assembly Guide

Structural Frame

Frame.png

To keep this as simple as possible a proof-of-concept frame can be made from wood.

A sketchup model of the frame can is available:File:Frame Sketchup Model.skp to explore.

Z-Stage

The best Z-stage we have seen is: Z-stage dipping mechanism made by the Sloth.

Vat

The vat is made from soda glass (the class in windows) and acrylic. Soda glass is used to allow as much light as possible to pass through from he project to the liquid in the vat. Clear acrylic can block up to 70% of UV light. Depending on the resin you are using this may be light you are relying on for curing the resin. For this reason soda glass is chosen as the material for the bottom of the vat.

You will need to cut the acrylic parts yourself or buy them from some source. The soda glass you can find in a picture frame, and can be cut to the correct size.

Vat Cad Files

Vat Slider File:Vat Slider.pdf made from 1/4" acrylic (make sure the acrylic is UV blocking)

Vat Walls File:Vat walls.pdf made from 1/4" acrylic

Platform File:Platform Rev0.1.pdf made from 1/4" wood

You will need to get a piece of glass, then cut it. Glass cutting kits are common the following image shows a piece of glass from a picture frame being cut to the vat size.

Next assemble acrylic components that make up the vat walls, it is recommended to use acrylic cement to hold the walls together.

Electronics

Arduino Uno.

The Arduino Uno will be used to control the printer hardware due to its low cost and wide adoption.

Custom Uno shield

This needs to be created, it will have two slots for stepper drivers and a linear regulator for the power supply.

Stepper Motors

DC power supply

Software

DLP Projector
