Editing 3D Printer

The hackerspace currently has 2 [https://en.wikipedia.org/wiki/Fused_filament_fabrication FFF] 3D printers available.

A [[#Prusa i3 MK3S+ | Prusa i3 MK3S+]] and a [[#Wanhao Duplicator i3 | wanhao Duplicator i3]].

There is also a stock of [[#Filament | Filament]] available.

== Prusa i3 MK3S+ ==
Bought as a kit with member donations with the intent of having high quality, reliable and easy to use 3D printing available in the space.<br />
Primary contact: [[User:Evils | Evils]]<br />

=== Usage ===
This device is well documented on [https://help.prusa3d.com/en/tag/mk3s-2 their website] and elsewhere on the internet.<br />
Despite this, use of it is limited to those who have received '''training on this specific device''', by someone who has received training on this specific device.<br />
This is in hopes of informing new users of specific quirks.<br />

==== Sheets ====
We have a smooth and a satin print bed sheet available.<br />
'''Before starting a print, make sure the printer is configured for the sheet that is on it!'''<br />
* Printing anything but PLA on the smooth sheet without additional precautions is not allowed.
** See [https://help.prusa3d.com/en/materials Prusa's table of material compatibility for details].
* Each sheet needs a different height offset [https://help.prusa3d.com/en/article/first-layer-calibration-i3_112364 calibration] which can be switched using [https://help.prusa3d.com/en/article/steel-sheet-profiles_1955 profiles].
** Because the inductive sensor does not sense the coating thickness.
See [https://help.prusa3d.com/en/article/flexible-steel-sheets-guidepost_2195 Prusa's guide on print sheets for an overview and more details].

=== Notes ===

* The front right heated bed retention screw's head was stripped during installation.
** There should be a spare in the spares bag, swap that in if it is ever undone.
* The minimum size for a stone base seems to be 28*35cm.

== Filament ==
There are usually several spools of filament in the hackerspace.<br />
=== Usage ===
* Any spool marked with an owner and a price can be used by anyone that pays for the used filament.
* Any spool not marked with an owner can be assumed to be property of the printer/hackerspace.
** Any such spool not marked with a price can be used at typical market price for the material.
*** Please mark such spools with the price when you determine one.
** Pay for usage into the <code>3D-printer</code> bar account, which can be used to pay for new filament and repairs.
* Unless marked otherwise, prices are assumed to be per 1000g and must have their unit marked (E.G.: €30).
* If sealed packaging is marked, make sure to transfer such markings to the spool itself on opening the packaging.
* Always return remaining filament to a sealed container to prevent moisture uptake.
* Inform the owner when you use a substantial amount of their spool's filament, or when the filament runs out.
* The empty spool remains property of the owner unless otherwise marked.
* Being allowed to use the filament does not include being allowed to use the printer.

== Wanhao Duplicator i3 ==
Owned by [[User:Sasja | Sasja]] and put in the space to make use available to others.<br />

=== Usage ===
This device is free to use after receiving training on this specific device from someone who has received training on this specific device.<br />

Always level the bed before a printing session!<br />

This device is fitted with an after-market print sheet similar to Prusa's smooth sheet described in [[#Sheets | Sheets]].<br />
However, due to this sheet being held on by a magnetic sticker instead of magnets in the heated bed,<br />
the maximum allowed temperature is 75°C.<br />
This device accepts the same 1.75mm filament as the Prusa.<br />

Build volume: 200*200*170mm (X*Y*Z)<br />
(Z is limited by the filament's ability to get into the extruder, and some cabling)<br />

The minimum size for a stone base seems to be 41*39cm.<br />

==== OctoPi ====
This device is connected to a raspberry pi 4 running OctoPi (a pre-made Raspbian running OctoPrint).<br />
That pi is equipped with a USB controlled relay to switch off power when the printer is not in use.<br />
That relay prevents usage of the machine from its control panel, use http://octopi/<br />

==== Unattended Operation ====
This model of printer is known for [https://hackaday.com/2016/09/17/possible-fire-hazard-wanhao-recalls-duplicator-i3-3d-printer/ spontaneously] catching [https://blog.adafruit.com/2017/03/23/the-melzi-problem-or-why-did-my-wanhao-i3-duplicator-catch-on-fire/ fire],<br />
unattended operation is absolutely not permitted!

== Wanted ==
* Reasonably priced automatic fire suppression that won't be triggered by a smoke machine.
* Indicating desiccant in dust proof packaging for the dry boxes.
* Draft resistant enclosure(s).
