Ultimaker printers

The Makerspace has three 3D printers, the Ultimaker2+, the Slightly higher Ultimaker2 extended+ and a Fancy Ultimakler 3 something with 2 nozzels.

• Ultimaker2 series website
• Wiki page about our Ultimaker2 printers, including how to's
• Ultimaker 3 -- not yet documented. Possible manual and, see page 11, filament diameter of 2.85mm

The ultimaker 3 buildplate camera can be seen remotely through mijn.makerspaceleiden.nl (but only if it is actually switched on and running/printing).

Software

For the design of 3D models, the following software can be used:

• Open scad - Openscad is a open source software for creating solid 3D Cad objects (available on Wndows, MacOS and Unix/Linux). Openscad is a scripting language
• Fusion 360 Fusion 360 is an integrated CAD/CAM/CAE software to design 3D models. For personal use it is free of charge (available on Windows, MacOS)
• Tinkercad Tinkercad is a free, easy-to-use app for 3D design, electronics, and coding.

Any CAD software that is able to convert your design into a STL files is suitable for designing for or 3D printers. Alternatives are Sketch and Blender.

Using a SD memory card

The Ultimaker printers at the Space need a GCODE file as input. You can put your GCODE files on a SD memory card and insert the memory card directly in one of the Ultimaker 3D printer. The memory cardslot is on the front of the printer.

• If you need to format your SD memory card (e.g. on MacOS), choose FAT32 and Master Boot Record (MBR) -- note that you need to expressly select FAT32; not the (new default) 'ExFAT'.

If you have a design file e.g. from Internet or a design program you need to convert your file, to the GCODE format or Ultimaker 3D printers can work with. STL is a common file file format and the easiest to to convert to GCODE. If you have a design in an other format it is possible to first convert this to the STL file format. Search with google for online conversion tools. (If you find a conversion tool, that gives good results, feel free to add URL here)

STL file can be converted into a GCODE by:

• Cura Cura is used to slice the model and prepare the GCODE (file extension .NGO)
• Slic3r Slic3r is used to slice the model and prepare the GCODE.

Using a laptop

There is also the option to directly print from your laptop, without using a memory card.

• PrintRun allows direct control of the printer and offer more opportunities than Cura/Slic3r. The GCODE file is uploaded via the USB connection on the backside of the printer.

The printing process

Once you have your printable GCODE file on a SD memory card, or your laptop ready and connected, goto Ultimaker 2 for a step by step tutorial of the 3D printing process.

Cleaning the ultimakers

Het komt ongeveer hier op neer:

• Maak de glij-assen schoon met een niet-pluizend absorberend papier (keukenpapier) en breng er een beetje verse (naaimachine) olie op aan. (dunne olie).
• Maak het trapeziumdraadeind schoon met niet-pluizend papier en breng een beetje verse magnalube aan (Het groene spul uit de Ultimaker-onderhoud la). (Dik siliconen? vet)

Verder kun je de glasplaat afwassen zoals je dat ook met een glazen ovenschaal zou doen (Afwasmiddel, heet water, sponsje, en niet laten vallen. Goed afdrogen alvorens terug te plaatsen).

Losse frutsels filament kun je met stoffer-en-blik of stofzuiger verwijderen, en met een zachte, niet pluizende doek (microvezeldoekje, evt. heel licht vochtig) kan de rest van de printer schoongemaakt worden.

In een bakje naast de UM3 vind je de spullen die nodig zijn voor normaal onderhoud.

In de ladekast onder de electronicatafel vind je een lade met onderdelen en accessoires voor de UMs

Ultimaker fans

The fans on the UM2+ have been replaced on 28-02-2020. New fans ordered from | MakerPoint, "fan pack 1699".

Hotend fan was noisy after about 1500 / 1800 hours of printing.

	Ultimaker	Sunon
Hotend fan	DF02500705BU-501	mc25060VI-000u-A99 (5V / 0.58W Maglev)
Object fan	DF0301012BM-501	?

These fans are the same for both Ultimakers.

Mail from deelnemerslijst:

De oude hotend fan (die herrie was gaan maken) is eentje met een Ultimaker stickertje erop, en nummer DF02500705BU-501
De oude object koel fans (2stuks) hebben nummer DF0301012BM-501 (Eveneens Ultimaker. Ze maken ze vast niet zelf, maar dit is hun opdruk)

De nieuwe fannetjes komen uit het Ultimaker "Fan Pack 1699”, besteld bij makerpoint.
De objectkoelfans zijn exact dezelfde, dezelfde nummers.
De hotend fan is een Sunon Maglev mc25060VI-000u-A99  (5V / 0.58W). Daar staat verder op: F9620p en TP CLX.
