What is RepRap

RepRap is a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap can print those parts, RepRap is a self-replicating machine - one that anyone can build given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend…

If you want to start 3D printing in brmlab, continue to Prusa MK2 subsite about our main, most user-friendly 3D printer.

Printer status

Drevena REPRAP printer:

  • status: working Move but bot work 8-). Service in progress. More on issue page.
  • set all speed max. to 70 (especially check translation speed), first layer 30% and small perimeters to 50% check Z-axis when starting printing !!
  • printing mechanics in nearly 100% condition (thx 2 axtheb, ray and pborky), slightly broken glass but fully usable.
  • web interface: http://drevena.brm
  • config issues - please check details here

Zluta REPRAP printer:

  • status: 8-O not working - Undergoing maintenance (reprinting parts, maybe there'll be some minor improvements in the process)
  • “quick-Z axis tuning” is needed whenstarting printing !!
  • web interface: http://zluta.brm

Prusa i3 MK2:

  • Aim to buy a kit of the current state-of-the-art 3D printer that should Finally Work™

Software a workflow

When you want to print first you need to create or acquire 3D model. Than you export your 3D model to .stl , this format is pretty much universal format for 3D. Than you open f.e. slic3r with correct config files and convert .stl to .gcode which is list of XYZ positions and amount of extruded filament. Than you upload .gcode to printer, do preparation and start printing. Everything should be nicely covered in this links:

Basic RepRap dictionary [CZ]

jednoduchý slovník pro rychlou orientaci

  • X-axis - levo-pravá osa
  • Y-axis - předo-zadní osa
  • Z-axis - výšková osa
  • extruder - to co jezdí po levopravé ose a posouvá filament
  • hotend - vše co je horké - jedná se o trysku, kovový chladič a ohřívací blok
  • nozzle - tryska - špička ze které je nanášen horký filament
  • heatblock - kovový kvádr do kterého je zasunuté teplotní čidlo a těleso sloužící k ohřevu
  • heatsink - zpravidla se myslí to, co spojuje zbytek extruderu s heatblockem, zajišťuje aby se nerozehříval plast ze kterého je extruder od rozehřátého heatblocku.
  • bed - “lože” - to na co se tiskne model, většinou se jedná o plošinu na které je vyhřívaná podložka a na ní je umístěno sklo, případně karbon
  • bowden - “dutá hadička” - způsob distribuce filamentu - filament je posouván mimo vlastní extruder a na tiskovou hlavu je zaveden právě pomocí bovdenu

Why do we have it?

  • Because many other projects need to make their own parts, and it greatly extends our ability to make wonderful stuff
  • Its fun to work on RepRap itself
