Line 1:
We have many 3D printers. All of them are fused filament fabrication (FFF) printers. A variety of thermoplastic filament materials can be printed, but not all available printers are capable of these.
All of Fat Cat Fab Lab's 3D printers were graciously donated or found. Special thanks to [https://www.mfgriffin.com/ Matt Griffin] of [https://ultimaker.com/ Ultimaker], 3D Hubs, [https://www.seemecnc.com/ SeeMeCNC], Emily Chapman,

Print Core nozzles cannot be changed! Dual printing limits width to 197 mm

== Materials Policy ==
Members are encouraged to bring their own filaments for printing and store them in their bins when done. Below and above the main 3D printing table are various spools of 1.75mm and 2.85mm filament donated by others which are free to use. Any
When all donated filament is gone, that's the end of it, and you must purchase your own.
== Build Plate Preparation ==
Line 67 ⟶ 91:
Certain high temp materials will stick strongly to glass and can crack it. For those, it's better to remove the prints before the glass cools fully to prevent this (ex: PC).
== Changing Nozzles on Ultimaker 2+ Printers ==
{{Note|Please return printers back to 0.4mm after use or leave a note of what size nozzle is installed -- nozzle size indicators are on the printers for this purpose.|warn}}
{{Note|Do NOT attempt to remove nozzles from Ultimaker 3 print cores!|warn}}
Ultimaker 2+ printers equipped with Olsson blocks can have their nozzles easily changed. Default for all applicable printers is 0.4mm (excludes Z-Unlimited).
The hot end must be fully heated and material removed prior to changing a nozzle, otherwise damange to the hotend and printhead will occur. The following directions must be followed for nozzle changing.
Line 94 ⟶ 122:
* 0.6mm - 2 dimples.
* 0.8mm - 3 dimples.
=== Olsson Nozzle Torque Wrench ===
Files for the torque wrench can be found here: https://www.youmagine.com/designs/nozzle-torque-wrench
* Required items: 7mm socket with 1/4" square hole.
* Material: PLA+ (proper torque), CPE, PETG
* Print settings: 0.15 or 0.20mm layer height; Solid, 10 walls; 95% infill, No supports.
== Bed Leveling ==
Line 115 ⟶ 150:
For mechanical and electrical failures of the machines, please stop using the machine and notify the #3dprinting Slack channel with the issue.
==
Fusion 360 can be used to model your 3D parts. There is a separate page [[Software_modeling|Software modeling]] which explores modeling software and offers advice and workarounds.
== 3D Printer Maintenance ==
Some regular maintenance is required over time. Below are listed roughly in order by descending frequency of required maintenance/adjustment.
Line 130 ⟶ 168:
Belts should be taught. Loose belts will cause parts to be dimensionally inaccurate in one or more axes (X/Y). This can be viewed easily by printing a cylidrical shape with its axis in the Z-direction. Generally, the belts that need retightening will be the shorter belts on the X/Y motors. First pluck the belt and remember its feel and sound. Loosen the 4 motor mount screws and push down on the top of the motor very hard as you retighten the screws in a star pattern. Pluck the belt and it should twang higher pitched when tightened.

There are 3D printed tools for this for the Ultimakers. Ask David Choi (macakcat) if you'd like to learn how. Instructions [https://support.makerbot.com/s/article/1667412443401 here] but they aren't fully comprehensive.
=== Cooling Fan Cleaning ===
Dust will collect on all fan blades and in the center fan heatsink. Hold the fan blades and blow with compressed air or wipe with damp cloth. Removal of dust collected on center heatsink may require disassembly of the print head. Do not apply strong pressure to the fan blades, they bearings are very fragile and may break.

The Feral Printer was found on the streets of Brooklyn. It's found a new home with us and has been modified into the [https://www.kickstarter.com/projects/1661525705/z-unlimited-add-on-for-ultimaker?ref=card XXL Z-Unlimited].
Line 156 ⟶ 191:
* Nozzle Size = 0.8mm (or whatever is installed)
* Compatible Material Diameter = 2.85mm

=== Important Information ===
Line 166 ⟶ 206:
* Try to keep the print hollow with 0% infill for really tall parts. But if you need to add infill, you usually don’t need more than 10% infill since the nozzle is a much bigger size
=== Preparing for a Print on Z-Unlimited ===
IMPORTANT - Follow these steps exactly!
#Raise the printer before loading filament by using the Move command in the menu.
#Manually 'Move' filament to prime nozzle before starting print. The filament under-extrudes in the beginning if you don't do this. We could make changes to the firmware but looking for it on the internet is a task the person typing this is not willing to do at the moment.
#Commence print file normally.
== Using Ultimaker 3 ==
The Ultimaker 3 printer uses print cores. We have 0.4mm AA and BB cores. The nozzles on the cores cannot be changed.
The AA print cores can be used for printing: PLA, PLA+, PETG, ABS, CPE, CPE+, Nylon, PC, TPU 95A, PP, and Breakaway.
The BB print core can be used for printing: PVA (a water-soluble support material).
See Print Core Compatibility below for more information.
=== Print Core Compatibility ===
Material compatibility depends on print core type and nozzle size.
{{Note|PVA should NEVER be used in AA cores! PVA can only be used in BB cores and BB cores should only be used with PVA to prevent contamination. |warn}}
Items marked with 'Exp' are experimental (some tweaking may be needed and your results are not guaranteed).
