Hey guys, quick one, looks like building a 3D printer (mechanics) is fairly straight forward, so does one just build the mechanics then apply software ? if yes how does the software know how long the X Y Z axis is and where the laser is..etc
Or does a 3rd party company do all that for you ?
Laser? What laser?
Laser cutters have lasers, 3f 3D printers have extruders, some 3d printers use lasers and resins, some use UV panels.
A read up on wikipedia or other sites explaining how 3d printers of all types might do you some good.
And to know the length of the various axis, there are end stop switches, so when it bumps into the switch, the software knows where it is.
Some hardware requires certain software, others require others. Your printing and design style will require another set of software while other people prefer another. You just have to to match the right stuff.
Laser as in the part that cures the resin, so SLA 3D printers or even DLP printers.
Well, some printers come premade, so the 3rd party would do that. Some are kits, so you would have to build it, and some are in between. It all depends on what printer you're using. The motion control software runs the positioning.
ok, i was asking because i would like to build a 3D DLP printer, i have the hardware figured out just need software to make it work.
Err... yeah... going down the path of an XY problem here.
Well, at least you haven't built it yet, as you're going to find the hardware you have laid out probably won't work 100% with the software you finally decide upon. So, find the software close to what you want, and adjust your design. Or edit the software/firmware to match your design.
I see, ok so find a software and work off of that which is the first i'm haring if this as i see allot of people online that seem to build then go hardware but that fine detail maybe overlooked when they are typing there "how tos"
Ok, so any good software companies or do i Google 3D printing software (which seems to come up with CAD)
While it's pretty common for people to build their own hot plastic extrusion printers, DLP is a whole 'nother thing. (And it doesn't use lasers - that's SLA). DLP printers use a digital projector shining through the bottom of a clear tank to catalyze a whole layer at a time against a build platform, which then raises up a tiny bit and the process repeats. Unlike the more common type of printers, the software that runs them isn't widely available. You might look at the B9 Creator, which is a DLP printer that's popular among jewelers. The firmware runs on an Arduino, and the software started out as an open-source project, although I'm not sure how open it is at this point.

I was planning on builing one myslef, a DLP is going to have faster build times as it projects layer by layer rather then cure the whole layer one spec at a time (SLA)Quote:

I would like to build a DLP, the hardware is fairly easy but its the software that's scratchy.
Have you looked at the cost of resin?
To actually answer your question. The software doesn't know your xyz dimensions, you have to tell it. In your case if you want to build a DLP printer, max X and Y are determined by how far away from Z=0 the projector is mounted. Further away = larger print area but lower resolution while closer is exactly the opposite. Then set that maximum X/Y dimension in your slicer software. You will also need to set your Z max in your slicer software BUT you will ALSO have to setup your Z axis in the firmware in your printer for things like steps per distance traveled (inches or mm) and possibly max and min Z depending on what firmware you choose.
So to summarize, YOU tell the software what the XYZ max dimensions are, it won't know all by itself.
If you buy a kit or pre built machine the seller has done that work for you as far as the firmware is concerned. If they provide a slicer they have likely done the work there as well. If you buy a kit without a slicer then you will still have to set your max's in the slicer software.
Thank you for answering my question ! so in nut shell i should go ahead and build accurately as possible then software it up.?Quote:
