Quick redirection

Printer status

Drevena REPRAP printer : wokring, 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 ~100% condition (thx 2 axtheb and pborky), slightly broken glass but fully usable
Zluta REPRAP printer : working, “quick-Z axis tuning” is needed when starting printing !!

both printers are recently moved to new position, bed equilibration wasn't checked

Filament holder for drevena printer is in plan in the near future

In case of any problem contact 3D printing mentor

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…

Why do we have it?

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

Reprap User Group Czech Republic

Brmlab is the place where you can meet other RepRap users, build your own, ask for plastic parts or advice.

If you are interested in brmlab's reprap or want help building your own, contact us at reprap@brmlab.cz.

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

Collaboration posibilities

RepRap

Experimenting and improving can be pretty expensive. If you would like to support RepRap project you can donate us on consumption goods.

Polylactic_acid (whole roll, 2.3kg), thermoplastic made from sugarcane or cornstarch used for printing all that awesome things :)

Acrylonitrile_butadiene_styrene, another thermoplastic material
