Featured Thing!

Description

This is the design we used for the first batch of MakerBots. These are the lasercut design files you will need to make your own if you have access to a laser cutter.

what scale should this be

These may be a stupid questions, but how thick should these pieces be? Also what units are these files in?

has any one actually had a maker bot cut with the updated set of plans, did all the pieces fit together right. I pose this question because i have remade the pieces in Inventor and auto cad and even accounting for a reasonable amount of material being used in the cutting process, (kerf), the pieces do not match up in a way which seems conducive to producing a functional printer.

hay whats the best CAD software to start out with?

hintss on Dec 8, 2010 said:

depends, what are you making?

Anonymous on Oct 5, 2010 said:

I've got access to a laser cutter, and I can get PCB's done. Making as much of it myself as possible, and striping some parts of old printers and the like, how much would it cost to make one of these?

hintss on Oct 27, 2010 said:

theres something in the repstrap section of the reprap wiki. pirated makerbot or something like that.

hintss on Sep 26, 2010 said:

so many designs here that wouldn't work on thing-o-matic :(

MakerBot on Sep 27, 2010 said:

huh? the Thing-o-matic is a MakerBot and we'll be making them for a long time. It can do all the things the Cupcake can do, but better. :)

For anyone wanting to lasercut them yourself, Copy and paste the numbers from cupcake/trunk into notepad then Save as WHATEVER_YOU_WANT.dxf and where it says save as type, select all files. Encoding ANSI will work fine. then open up your .dxf file in whatever software you use. :)

Hey, i'm really interested in getting started on this project, and i know someone who has a laser cutter, i'm just wondering which files i have to download? since the files at the top of the page under http://svn.makerbot.com/trunk/..., are just text with a whole bunch of numbers :S

andyward on Apr 28, 2010 said:

Since there are different files on this page... I'd like to ask, "Which one is the most complete and up-to-date for laser cutting parts? I do a lot of work in Stainless Steel. I have a plasma table (which I figure is too "coarse" for cutting these out.) But, have a friend with both a waterjet and a laser. I'm thinking hard about Stainless, but, might go ahead and get a sheet of aluminum.

Can you tell I over-engineer things? Still, in a metal fab business... you use what you have.

Please let me know. Thanks!

Hey andy,

If you scroll up a bit you'll see:

This is the coolest invention, and Bre your probably the coolest inventor! I :-D

What is the highest printing resolution in dpi?

BenRockhold on Jun 4, 2010 said:

You cannot easilly measure the machine in dpi.
Or voxels.

It lays down a filament of semi-molten plastic between .1 and .5 mm in diameter (depending on the nozzle attached).

We're building our first bot for the student fab shop in the College of Design at the Uof MN. I noticed after cutting out all the case parts that the source code posted here is for batch#1. Surely changes have been made from batch#1 to batch#11: does anybody know where revised source code can be found?

Duh, just found up to batch#5 here: (thx SSD)
http://svn.makerbot.com/tags/ and http://svn.makerbot.com/trunk/
but that still puts us 6 batches back. Does anybody know changes that have been made between the b5 and b11 source code?

We're making the case and as many parts as possible from hard
board: tough, flat, stable - lasers pretty well with our 120W X2_SS. So far so good, the hardware and electronics arrived on Friday: hopefully we'll be printing parts by mid-week.

The latest versions are available scattered under http://svn.makerbot.com/tags/ and http://svn.makerbot.com/trunk/

Electronics are at http://www.reprap.org/bin/view...

This looks like a slightly older version of the files since I think I see the mounting point for the tape dispenser. Could you either update the files or at least post a pointer to permanent home of the repository files? While I'm assembling #330 for its owner, I am taking a serious stab a doing my own frame - I bought the plywood last week and should be able to get it cut by Thanksgiving.

@David - I just got my plywood at Lowe's for about $8 per 24"x48" panel. After a rough calculation of the amount of wood needed, I come up with about 10 sq ft of raw stock, or more, depending how I combine multiple parts to fit in the laser cutter, so I think it's going to take two of those sheets with lots left over for cutting other things or spare parts.

Hi makerbot team,

is this the latest revision of the design? I am looking into getting it made at ponoko or in a laser cutting shop nearby. Found the design you uploaded to ponoko, but it doesn't match with this one here. Any clues on this?
Furthermore, any chance to get the designs for the plastruder uploaded here, too?
Thanks!

What software are you using to generate code and slice your objects?

Do you have any advice on sourcing 5mm birch plywood? Is it generally available in hardware stores, or is there a particular google query that would be helpful?

Anonymous on Jul 11, 2009 said:

Heres what i have so far. Trying to get ahold of the right thickness of acrylic turned out to be more difficult then anticipated. Ended up with 4.5mm walls. But its coming together. Enjoy the awesomeness of see through!

Anonymous on Sep 9, 2009 said:

Hi, could someone supply a copy of the Gcode files used to cut the acrilic parts of your MakerBot, please ?
I've tried to work it out from the MakerBot data base, but cannot make sense of the data.

Perhaps, at 74, I'm too old and dodery !

Regards, Grant

More pictures! Im gathering scrap acrylic and old stepper motors to see if i can make the makerbot as cheaply as possible!
Shhh..dont tell my friend i took his skateboard apart for the needed bearings... :-D

Any reason why we couldn't cut one of these on a cnc machine? (might have to adjust to allow of the 'kerf' of your bit. and overcut the corners?) Any thoughts on that?

Anonymous on Jun 29, 2009 said:

i'd love to see that. we use a lasercutter simply because that is the tool we have available. we've been toying with the idea of getting a shopbot and using that for production work, but just haven't gotten to it yet.

want to try it and report back?

Anonymous on Jun 14, 2009 said:

Is there a specific reason for going with wood for the body, or can the body be built with acrylic? I would like to build mine with clear acrylic, but want to make sure wood wasnt chosen for vibration or sound insulation. :-D
Thanks! Awesome machine!

Anonymous on Jun 14, 2009 said:

Acrylic has a binary fail. If you screw any nut down just a bit too hard you'll ruin the entire piece. Also, wood is a lot easier for you to drill and modify it as you please.

Still, we'd really like to see one made in acrylic!

Hi a frind of mine sent me to this website to see if I could down load a file for the cupcake cnc to cut on my laser. I use Coreldraw to run my laser and did not see any cdr files. I down loaded the file cupcake-x-stage.dxf and tried to import and it didn't work any thoughts?

Anonymous on May 26, 2009 said:

Hey Laser Man,

We use coreldraw to lasercut all our files and import them just fine. there are a few things to keep in mind:

1. 3d projection is 'top'
2. the units are mm.
3. make sure auto-reduce nodes is checked.
4. click to place the corel draw file once you import it.

we use coreldraw 12. i used X4 the other day but it messed up all the colors, although it did import the curves just fine.

I am looking forward to building mine as soon as I get my parts 8-) . Until then I will mess with the CAD files to increase the build area :-P . Thank for this fantastic machine!

Anonymous on May 4, 2009 said:

QCAD tells me the total length of all entities in cupcake-x-body.dxf is 29097.1. I removed all the endstop washer type things, which reduced the total length by 14% to 25067.3. You should consider manufacturing these components independently, so you can reduce the laser cutter time per makerbot.

After my experience laser cutting some gears I wonder if the makerbot can be laser cut more efficiently by planning the path of the tool head.

are the x and y stages and the body all cut from 3/16" plywood?

body cut from 5mm birch plywood, small bits from 1/8" aircraft grade plywood
