Switch cuts out 3D printing problem

3D printed table base - Kevin CaronAbout a week ago I decided to tackle a project I’ve been thinking about for a while. I have a beautiful glass tabletop and thought it would be fun to 3D print a base for it.

Fun?! I like to go into a project thinking positively, but maybe that just set me up ….

Anyway, the first day of what would be a 5-day print went fine. It was when I had to change out the 5-pound spool of PLA filament on my 8-foot-tall Cerberus 3D Gigante 3D printer that things went terribly wrong.

The print paused normally, then I switched out the spool of natural filament and loaded up the new spool. When I tried to resume the print, though, everything went haywire. The printhead swung wildly out of position, and the print was lost.

I was ready to pull my hair out! A whole $100 spool of filament and a day of 3D printing had been lost. Not to mention the frayed nerves.

Then Steve Graber, the man who built the Gigante, told me about the switch ….

Seeing in 3D – Using 3D printing for prototyping

3D printed stem of Schubertii sculpture - Kevin CaronWhen 3D printing first became popular for more general use – it’d already been around 20 years in industrial and scientific settings – “rapid prototyping” was the buzzword you heard everywhere. (After I started working with 3D printing and especially my 8-foot-tall Cerberus 3D Gigante 3D printer, I found this hilarious – there wasn’t much rapid about it.)

While I do create sculptures using 3D printing, I also use it for protyping. It’s really important when I’m creating a sculpture in CAD and then actually building it in metal to be able to see all aspects of the form.

A great example is a sculpture I’m just beginning, Schubertii. Based on the plant by the same name, this sculpture will be 12 feet tall. Seven feet of that will be the sculpture’s “stem.”

The stem is fairly simply to look at, but creating it in metal is going to be, well, challenging. Its round edges and flowing form will require me to use a combination of tools – air shaper, English wheel, maybe even the slapper (yeah, there really is a tool called a slapper) – to get the rounded form that is the opposite of how metal comes, in flat sheets.

To get the form right, I printed the stem maquette, or model, on my Cerberus 3D 250 desktop 3D printer ….
