The Fabsterdam Photo Studio

For a while, we’ve been thinking about upgrading our photo setup. We take most of our pictures with our phones, for convenience, but it’s difficult to get nice pictures of small, 3d-printed models this way. Using a ‘real’ camera helps, but for really nice pictures you need a light box. This is essentially a box-shaped diffuser that gives you a nice, even, white background with uniform lighting. Rather than paying a lot for a commercial one, we decided to give this DIY Light Tent project a go.

We’d been reading about this technique called ‘vapor treating‘, that is supposed to smooth out the surface of prints. Bathing them in vapor of a solvent would blend the ridges so typical of 3d printing, so that the part would look almost injection-molded. This looked like something we’d like to try ourselves.

Different plastics require different solvents. The solvent for ABS plastic is acetone, which is both widely available and not too toxic. We have a lot of pieces lying around from semi-successful ABS printing experiments which are perfect candidates for some smoothing.

Printing wood

We bought some wooden filament and it’s finally here. So today is wood printing day!
We’re still figuring out what are the correct settings for this filament but it looks so sexy in our printer that we wanted to share a picture of it.

Adding a print server with Octopi

For the last month we’ve been printing with the laptop attached to the printer, what we found pretty inconvenient because it takes a lot of space on our table.

Some weeks ago, we’ve heard about Octoprint, a web based print server ready to plug in a Raspberry Pi with any distro that has an http server installed. It looks like a great idea, but we found something even better: Octopi.

Octopi is a distro based in Raspbian with the octoprint server setted up, basically plug and play.¬† So we took one of the Pis that we have around and, I have to say, intalling it couldn’t be more simple!
