    I've been considering 3d printer options....

    I've been considering 3d printer options.... for a while now


    I have been investigating and researching this a bit in the past few years. I have a friend whom does a bit of it, as well as CNC milling on a micro-mill.

    I am a master fitter and machinist, currently training to program CNC machines.

    Things have developed somewhat since I began researching... there is probably plenty of writing I could do here, but a few thoughts... considerations

    -I think the dual head method is the way to go, using the PVA as soluble filler.

    -Dual head vs Dual filament : Is dual filament really that messy?. Is Dual head result noticeably better?

    -Heated/cooled enclosure? Heated bed? ... Both?

    -Print volume?

    -I would have thought the ramps/forming aspect may have a home here, given 3D printer could be used to print custom moulds?.

    -What is going to be the most effective way to "sample" or "capture" the dimensions of an existing object? (and generating a 3d file)? M.S. k-nex?


    Here are a couple of random references...

      I'm going to give the Xbox 360 kinect scanner a go. It should be interesting.
      For $17 It's worth a try. [emoji6]

          i did alot of research last year into 3d printers using excel spreadsheets and the flashforge creator pro is the best printer for the pricepoint. Its a copy of the ultimaker if i remember right. Thats what i was going to buy but its heaps cheaper. Best price i could find was in South Australia from an education website.
          It gets great reviews and has a large online community if you need help also.

            I was considering a cheap ebay 3d scanner thats like $150, but I think I might do some more research on the Kinect scanner as well, now that I know you can use them.
            cool idea

              are 3d printers any good at making useable small parts e.g like d-pads for example?

                Yep

                What's a d-pad?

                *you could make a new opto interuptor for your judge dredd, or similar game... for example. That part is available though, but for unavailable parts has great potential...

                  The finish isn't perfectly smooth and I wouldn't use parts made from PLA in a pinball machine where they're going to be hit by a ball but I'd say it would work for a D pad (I googled it [emoji16]).

                    Thanks. I like the thought of making plastic parts but I have thought about cast moulding old school style. quite expensive from what I can tell. 3d printing good for models and parts that dont need strength from what i can tell. Is that what you think?

                      It all depends on the material and how you slice the stl file. You can make a solid object from ABS with 100% infill which would be a lot stronger than a PLA item with 20% infill. That's one that has like an internal box section construction. See the pic below.

                        It is allot stronger than I expected, Even the PLA is pretty tuff. It would easily take the shocks of a pinball hitting it all day. I can throw printed items on the ground really hard and it wont break

                          I have owned a 3D printer few a couple of years now (Rigidbot) but have only just installed dual heads BUT the precision of the print bed needs to be spot on for dual to work.My bed has a tiny warp so I can't get my two head setup to work.

                          Single head printing need precision but duel head need exact precision.It can be done but be aware it's a lot more work.

                            Does your dual head setup use the common rail?

                            I understand there are different methods of arranging the operation of the two heads, mechanically...

                            Do two heads move in unison? or two heads moving independently?

                            Is it hard work trimming away the props using one material?

                              On my rigidbot both head are next to each other and mounted on the same rail.This makes aligning the heads in the x and y easy but difficult to get them both level to the bed (z plane).
                              Removing support material can be difficult depending on the shape of the print but I always get a rougher surface left after removing the support.I just try amd make sure the piece is supported at a non important area.
                              There's a google page for the rigidbot if you want to see more.
