OpenExposer

Just fixed some bugs in the software. I think i can do first resin test with the new prototype this weekend.

The new open exposer firmware supports G-Code now. I also wrote some tools to handle g-code files.

The toolchain works as follows:

1. generate a stl file with your favourite cad software

2. sclice the stl to svg with slic3r

3. use the open-exposer slicer to post process the svg file and generate the g-code file

4. send g-code to open exposer with open exposer sender

All tools are written in python. I implemented a small plugin interface for the post processor. With plugins the post processor can be extended to handle different input file formats. By default it supports svg ( slic3r export).

Here is a small video which shows the exposure process with the new firmware.

After two weeks of hard work, finally i present you the new version of the open exposer 3D Printer....

I am working on a new printable Open Exposer Design. This is a first rough draft.

Today i worked until the late evening at our local Fablab. I finished the Open Exposer laser cut design. It contains the following components.

- Open Exposer base unit

- PCB Exposer extension

- Bearing extension

This weekend i will be at  Kerkrade Mini Maker Faire (NL) .

I am working on the pcb extension unit for the Open Exposer project. This is a first rough approach.

I will laser cut  the new Open Exposer design and the pcb extension on wednesday. I also designed a bearing extension for the bottom of the Open Exposer project.

I am just testing some materials. Hope i will find the best solution soon.

This time : copper (again), PVC foam and polycarbonate.

Here are some pictures of the first print test with the new vat tilt mechanism.

I still have problems with the build stage material and stickiness of the prints. I already tried acrylic and a copper plate. Any suggestions?

Mounting and unmounting the build stage was a time wasting process. So i decided to redesign the stage. I use magnets for mounting now instead of a screw.

After hours of designing and printing new parts... Here is the first test video of the new vat tilt mechanism.
