FDM / FFF 3D Printers

General info links on FDM/FFF 3D printing, and specific information on machines in basement.

Fused Deposition Modeling (FDM) is the most common term for this printing technology, but the term was/is copyright. Fused Filament Fabrication (FFF) was coined by the open-source RepRap (Wikipedia) community in 2005 to avoid legal issues.

If you're new to FFF printing, this is a decent general overview: https://all3dp.com/2/3d-printing-for-beginners-all-you-need-to-know-to-get-started/ (Full article, 3,000 words, broken into small section.)

Ultimaker S5 general info

The Basics (from manual)

RC has two Ultimaker S5 FDM printers.

S5s are dual extruder units, with a single print head. Depending on the "cores" (Ultimaker term, generic term: "hotend"), they can print in two colors of the same build material, hold extra build material on a 2nd spool to change supplies if one spool runs out, or print supports from alternate materials that separate more easily, or dissolve in water.

Print Adhesion

After some peeling/warping prints, I tried using a glue stick. It left marks on the print, as matte streaks (vs the glossy finish against clean glass).

From reddit:

PLA on glass shouldn't need adhesion help. It'll turn out to be one of four things:

Also, glass does best if allowed to heat soak a bit before you start printing - it's a reasonable insulator, so takes a while for the top surface to get up to temperature when heated from the bottom. Hot PLA on cold glass doesn't stick all that well.

This person says if you can feel the glue, it's too much, and needs to be buffed: 

The Ultimaker S5 glass bed can apparently be changed to a more typical steel flex plate: https://shop3duniverse.com/products/magnetic-flexible-pei-build-plate-for-ultimaker-s5

 

Ultimaker S5 - Zorro

RC has two Ultimaker S5 machines, this page is for Zorro specific info.

Ultimaker S5 - Luna

Needs flashing that requires partial (potentially dangerous) disassembly, or possibly new parts.

Possible documented fix: https://gr5.org/unbricking/
