Our ALtalk for May was brought to us by Angel and Ariel Lindo who talked to us about their new 3D printer and showed us how it worked.

1. What you need to know

2. Yourfirstprinter
Are you on budget?
Are looking to print a
variety of materials?
Are you looking for size?
Are you looking for a DIY?
Are you looking to plug &
print?
Are you interested in
printer technology?

6. PrintingSize
Bigger === $$$
big objects -> slice’em
Small objects -> print
slower for detail

7. DIY
With time you’ll need to:
Fix (stepper, nozzle)
Mod (fans ducts, pc comm)
Upgrade (hot bed, nozzle,
power supply)

8. PLUG&Print
Most - Branded printers
Clones - there’s a small
learning curve
you’ll need a slicer app
(ie. cura)
Models to print (ie.
thingiverse.com)
3D APP (ie. Blender3D)

10. Printertechnology
CARTESIAN
Classic printers, are the most popular
configuration today.
Move a printhead in two dimensions
on a plane.
DELTA
Delta configuration allows for higher
speed.
The printheads are lighter and they
use shorter paths from one point to
another.

11. BasicPrinting
settings
PLA Print temp: 210°C notes: print with fans
on
ABS Print temp 250°C notes: print with fans
off, heated bed at 110°C, don’t print too fast
Print Speed (quality vs speed)
Layer height
Supports (over hangs, brim, raft)
