We are Moving!

by nosrev


Hey guys,
its Fabian, the guy who created this Thingiverse Group. As Thingiverse is more or less restricted in using it as a Forum and since another great community member (called Drayer) directly gave me full permissions to his newly created Forum, I am happy to announce that we are going to move from Thingiverse to there soon! I am not going to delete any stuff here, but all new stuff will be posted there. Also i will make sure to copy old important threads over here and try to cross-link all information.

Join our journey and help us too improve our Forum: http://sparkmaker.freeforums.net/thread/2/welcome

Quick Setup

by nosrev

1) How to print

1.1) How to set up SD Card?

  • get an FAT32 formated SD Card (some SD Cards may not work, if so try another one)
  • Option 1 (pre-scliced .wow File)
    -- get a pre-sliced (.wow) File (can't recomment current WOW! Files - too low cure time)
    -- rename the (.wow) File to "print.wow" and put it on your SD Card
  • Option 2
    -- start SparkStudio (with administrator privileges)
    -- import an .STL File (.wow Files currently can not be imported - these are pre-sliced binaries)
    --- example STL-File: http://www.thingiverse.com/thing:2795935
    --- design an STL-File yourself using 3D modelling tool (e.g. https://www.tinkercad.com/ - no download needed and very simple to use)
    -- select your position, size, etc..
    -- press slice
    -- chose your resin and layer hight
    -- press slice
    -- save file to your SD Card

1.2) Optional modifications (recommended)

Solid Resin
Cured solid resin can be disposed of in the trash.

Liquid Resin
WARNING When handling resin wear protective gloves/protective clothing/eye protection/face protection
Uncured liquid resin must be disposed of according to local regulations. In some jurisdictions, e.g., California, it is classified as hazardous waste. Contact your local municipal waste system for guidance on proper disposal.


If you cure liquid resin before disposal you can dispose of it in the trash. To do this, pour the resin into a transparent plastic bag and leave it out in the sun for a week or so. Exposure to the sunlight will cure and harden the resin, at which point, you can safely dispose of it in the trash.

Filtering the Resin

by Azgang

Do you filter your Resin after each print?

I was reading on another forum that not filtering the resin can lead to dark spots on the lcd screen.

If you do filter, with what? and How often? If you don't filter what do you do with the resin after use?

I guess another question then, where do you store your resin?

Using the FHD Upgrade kit to make a second sparky?

by Varulven

Hi guys,
I have an old sparky and are, like I assume a lot of you guys, waiting for the promised FHD that will be delivered... after the summer?

Anyhow, if you look at what that replaces... I am under the impression that once installed, you can take the pieces you took out, add a box, and a Z stage and have a new "original" printer...?
