My next step in ‘infill only’ logo printing is using color instead of density to accentuate a logo. My Leapfrog Creatr is dual headed so it would be logical to start with color, but my machine is not capable of dual printing this kind of detailed color changes. It will print two colours in one print job, but there’s too much ‘bleeding’.
My printer is from 2013. Last year Leapfrog launched a new milestone in 3D printing: BOLT. Some weeks ago I asked Leapfrog if opqrstu3D could test a BOLT on an ‘infill only’ print job. Two weeks ago I got an invitation and last Friday was my first BOLT-day. I do unbelievable things with my 
Creatr, but BOLT is a completely different machine. There are loads of new features Creatr can only dream of. Check it’s specs at the Leapfrog website. For this two color logo print job, the most important difference between Creatr and BOLT are the independent extruders. These allow much more accuracy in dual color printing.
One small problem was the slicing. I use Slic3r, at LPFRG they use Simplify3D. With the help of LPFRG whizzkid Joeri we fitted two STL’s in one BOLT Gcode and the machine started it’s first ‘infill only’ two-color-logo print job. Opqrstu3D challenged BOLT to do something it had not done before and I did not now what to expect.
The outcome was far beyond my expectations. BOLT did an unbelievable job on a daring challenge. This is the coolest ‘infill only’ 3D print ever. It’s a first try, when we fine-tune the settings it will even look better.
Next, BOLT will print the Leapfrog logo.
