The incomplete REPRAP beginner's guide is an attempt to gather in one document all the basic information about REPAP MENDEL PRUSA, that is available in the internet.

The reason of doing it, is that it is sometimes more practical to have some basic information gathered in one place, than trying to get fast and accurate answers, for issues that a newbie cannot even understand and express.

Mostly this work is a ‘copy&paste’ of documents and websites scattered in the internet, and irc dialogues that took place in the irc #reprap, which I had the chance to log.

Although it is focused on the Mendel Prusa model, I hope it may be useful for builders of other models.

Under no circumstances this document can be considered as complete.

Introduction

What is 3D printing?

…“3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.”

(https://secure.wikimedia.org/wikipedia/en/wiki/3D_printing)

…“A large number of competing technologies are available to do 3D printing. Their main differences are found in the way layers are built to create parts. Some methods use melting or softening material to produce the layers, e.g. selective laser sintering (SLS) and fused deposition modeling (FDM), while others lay liquid materials that are cured with different technologies. In the case of lamination systems, thin layers are cut to shape and joined together.” (https://secure.wikimedia.org/wikipedia/en/wiki/3D_printing)

Reprap Mendel prusa is an FDM 3d printer. Here are some videos on how FDM works. You can find many more on youtube.

http://www.youtube.com/watch?v=cFcWFB0FlLo&feature=related http://www.youtube.com/watch?v=JVp92Nx7XMw&feature=related

…“Industrial 3D printers are made by companies such as Objet Geometries, Stratasys, 3DSystems and Z-corp. The average price of such a printer is €10,000 or more.” (https://secure.wikimedia.org/wikipedia/en/wiki/3D_printing)

I found these videos of commercial 3d printers:

Stratasys http://www.youtube.com/watch?v=itRcInOwbyM

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... …RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone……RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. It is described in the video on the right.” (http://objects.reprap.org/wiki/Main_Page)

… “RepRap is short for Replicating Rapid-prototyper. It is the practical self-copying 3D printer introduced in the video on the left - a self-replicating machine. This 3D printer builds the parts up in layers of plastic. This technology already exists, but the cheapest commercial machine would cost you about €30,000. And it isn't even designed so that it can make itself. So what the RepRap team are doing is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about €350). That way it's accessible to small communities in the developing world as well as individuals in the developed world. Following the principles of the Free Software Movement we are distributing the RepRap machine at no cost to everyone under an open source license (the GNU General Public Licence). So, if you have a RepRap machine, you can use it to make another and give that one to a friend... …The RepRap project became widely known after a large press coverage in March 2005, though the idea goes back to a paper on the web written by Adrian Bowyer on 2 February 2004.” (http://objects.reprap.org/wiki/RepRapWiki:About)

Adrian Bowyer explains his 3D printer RepRap: http://www.youtube.com/watch?v=Px-g1NMvLug

There are various reprap models such as:

NOTE: you must have in mind that choosing a mendel-like model, may be hard to find specific parts when these will/may brake.


Ok, I want one

Well done! Before you make up your mind you need to make some research on the subject. After all you are a newbie …..( since you are reading this).

Before reading further, you must understand that reprap is an open source project that is under development, and requires some technical skills (from soldering to crafting). If you are excited with 3D printing only and NOT with building, I suggest you buy a pre-assembled, commercially sold machine and don’t bother reading the rest of the document concerning building and fine-tuning.

Remember …“it's generally suggested not to buy a full kit because you will have a hard time finding someone to repair the machine once it does break. All 3d printers eventually break. If you INSIST on buying an assembled machine, try: Mosaic [1] Makerbot [2]” (http://ietherpad.com/UaMN2zn4sn)

For assembled-ready machines please read Acquiring

It is a good idea to read this document BEFORE you even start searching in the internet. This can save you time from unnecessary or misleading information. After reading, you may be more focused on what you want and how you are going to find it.

1st stop is the website of reprap.org. Here, you will find almost anything, although some info may be obsolete, other may be up-to-date.

http://reprap.org/wiki/Main_Page

I suggest you read A LOT. You can use the glossary to familiarise yourself with new terms (http://objects.reprap.org/wiki/Glossary), select one of the ‘how to build’ pages (http://objects.reprap.org/wiki/RepRap_Options) just to get the taste of what awaits you…. Also there is a search engine within the website that you will find very useful, since the tons of info cannot be easily found through page browsing. For example type in the search field: object, extruder etc. I found it quite useful as a dictionary for unknown technical words (i.e. heated bed)

The machine I am going to focus is this : http://objects.reprap.org/wiki/File:Assembled-prusa-mendel.jpg

All the necessary information about building can be found here: http://objects.reprap.org/wiki/Prusa_Mendel_Assembly


2nd stop is irc://irc.freenode.net/#RepRap (for chatzilla) or http://webchat.freenode.net/?channels=reprap a simple browser-based chat interface.

Those with IRC clients, simply select the freenode server, then the #reprap channel.

In irc you will get help right away, by very experienced users. Just introduce yourself and ask your question. In irc, information is up-to-date, although sometimes you may find difficult to explain exactly what is the issue that you are experiencing. This can happen because of language barrier and lack of technical experience. But don’t worry, almost everybody is willing to help.

3rd stop is the reprap forum at http://forums.reprap.org/ Here, your question may have been already answered. Check this thoroughly.


ACQUIRING

You have 3 options:

  1. build one (buy all the parts from different dealers)
  2. buy one complete Mendel (or Mendel-like) kit
  3. buy a fully assembled Mendel

Category 3 usually applies to models of category 2 but the models are sold already assembled. However, I wouldn’t recommend it since they are delicate and heavy for shipping:

“………..

  • Mendel-like Axis and Glider from botmill http://botmill.com/
  • Mendel http://thefutureis3d.com/
  • Skb-Kiparis ltd - Fully assembled 3D printer Gen X with new verticax X axis and new generation of electronics!
  • ac123dc -stampanti reprap 3d in kit ,-- RepRap Prusa assembled and tested Italy based
  • Greg Frost Mendel - Heated Bed, Machined Pulleys, Lm8uu Linear Bearings, removable glass bed, hinged accessible wades, all metal hotend.
  • 3dStuffmaker cheap Kits and fully assembled/tested units and plastics. Shipping world-wide. Launch Sep/Oct 2011
  • Mendbot Shop fully built calibrated reprap 3d printer, Metric Prusa, SAE Prusa, Mendel, Wade Extruder, almost complete kits, fully built plastruders.”

(http://reprap.org/wiki/Prusa_Buyers_Guide)

Category 2 is the playfield for the average amateur who does not know much about electronics, crafting, soldering, engineering, programming, or does not have easy access to all the parts needed to build a machine. It is for those who have fun building plastic kit models, or for those who have some experience with tools such as screwdrivers, multimeters, dremel, solders, etc. It is for the majority (like me) who want to build a printer fast and easy.

The recipe is easy: the kit comes in a big and heavy box, you spend some time building it (lot of fun for model kit builders), you spend some time calibrating it, you spend the rest of your time printing and sharing our knowledge in #reprap.

“………Full Kits

  • BotMill - Full 3D printer kits with many free extras. Variety of colors, blue, rep, yellow, green, white, black +more!

(http://reprap.org/wiki/Prusa_Buyers_Guide)

Category 1 is for the more experienced builders (ex-builders of category 2). Machines build that way cost considerably lower, about 50% less than category 2, but there is always the risk of finding parts with lower quality (like smooth rods that must be straight and very smooth). Nevertheless you have the overall quality control over each part, so you make your choices.

A reprap consists of several different types of parts:
  1. RP parts (repraped parts, that are used to mound the rods that make the frame, mound motors and x-y carriages). These are printed from another reprap
  2. Mechanical parts. Are the smooth rods (to slide the carriages) and threaded rods (to make the frame), nuts, washers, belts, bearings, springs etc.
  3. Electronics parts. The controllers of the motors. All these are connected to a main “controller” that reads the gcode from the computer and translates to motor moves. Today, the most popular electronics are Arduino with pololu shield (or RAMPS, http://reprap.org/wiki/Ramps ), Arduino with Sanguilolou shield (http://reprap.org/wiki/Sanguinololu )
  4. Electrical parts. Like cables, power supply, stepper motors, endstops, etc
  5. hot-end parts. This is the most tricky part to find/make. More info at http://reprap.org/wiki/DIY_Direct_hot_end
  6. The printer firmware. Sprinter by Kliment is the suggested FW for Ramps machines. It uploads to Adruino via the arduino control software
  7. The software. This includes A) the HOST software that connects the PC with the printer (repsnapper, or preferably Kliment’s pronterface), and B) the application to convert the solid model into a series of gcode instructions that your printer understands (replicatorG, or preferably skeinforge/SFACT-by Action68)
