    Speaking as someone who uses both types of printer - it's a big subject. There are many abandoned 3D printers gathering dust in the garages and sheds of the world!
    I have answered many queries already on this site, and my opinion has changed over the years too.
    There I a place for the FDM printer in our hobby but you will NOT be getting anything like the surface quality you are used to from injection moulded plastic and polyurethane resin, so Resin is unquestionably your most useful method. I use my FDM printer for bases and jigs and storage compartments etc but not model components. It's good for scenic and architectural components as well -especially if you need lots of the same thing, for instance window frames or brick walls-which is true for both types, to be fair.
    The main question though, as Jim R says, is what do you want to do with it?
    If it's because you want after-market parts that you can't get anywhere else, do you have the CAD skills to create it for yourself? If so then the opportunities are endless.
    If not you will be just as reliant on other people to offer the digital files to market as you are on manufacturers to produce them. And unless you are into fantasy models the ground is pretty thin out there in interwebland. That said if you do find a model that you want, whether for free or purchase, you can print it as many times as you like and in whatever scale you fancy. So if, for instance you are into wargaming you could print as many Shermans as you want to spend on the resin.
    And as Dave Ward says, do you like tinkering? Because all printers require some degree of it. As for the faff of resin printers- it's not so bad once you develop a routine.
    you should read Gary MacKenzie 's thread.
    Or many of mine have 3D printed bits in-for instance I made hobnail boot soles for my Napoleonic French Fusiliers(which I used on many lying down figures) , and a Flame Thrower and boot soles for US Marines for my Iwo Jima diorama.
    Anyway enough of my waffle. Good luck and keep us posted

      Cheers Neil more food for thought I come from an engineering background both marine and aerospace but have had no cad training or experience, are cad programs user friendly? as for the tinkering yes i'm always taking stuff apart

        1. look at the printing volume and the ''pixel size'' , not at 2k 4k 6k 9k etc

        2. when you know the print bed size check that the ''suggested'' wash n cure can actually take the print platform and not just prints in the tank ( experience here )

        3. you need the printer location area temp to be approx 25 degrees celsius, and the resin to be at that temp too for optimum printing with less problems.

        Its a learning curve, a lot of fun , and hair pulling , but when you get a print out you like , its amazing.

          Hi guys

          i have also been tempted by 3D printing and been following the blogs here and elsewhere with interest And spoke to a local #D printer, and i have come to the following conclusions:

          1 - to get near the level of detail of injected plastic or resin parts, a resin printer is needed.
          2 - although printer are available at around the £100 mark, much more needs to be spent to get the quality we are used to from kits.
          3 - there will be a fair amount of learning etc to really get to grips with 3D printing
          4 - unless there are print files available for the subject you need, then skills are needed to create my own.
          5 - '4' will take a significant amount of time to master - I have bought Nomad Sculpt and it is straight forward to use, but will take a lot of learning to master!
          6 - the learning curves will be a distraction from actual modelling.

          my conclusion is that, given the significant learning curves 3D printing will take a lot of time, reducing my time for actual modeling so should be considered almost like new hobby in itself, rather than a source of models. So a more practical solution is to buy the files and get them printed by other service providers.

          As I mentioned I have a copy of Nomad sculpt and am learning how to use it. I have bought the files for a couple of heads (copyright free) and as part of the learning process I have modified them and currently having them printed by a 3D printer I found online. The files cost £8 for the and the heads £20 to print, including delivery.

          interestingly, when I went to a local printer and showed him the file his reaction was that their resin printer which cost 'over £100"would not "get anywhere near the quality" I need.

            Probably the same for most people, Peter. I only have a head start for my age because I used the technology at work for 29 odd years

                  I rescaled the, to be 1/10th scale when printed at 100%

                    Where would you dispose of the saturated water?

                      Good point Brian. I've not really looked into it much but I guess you wouldn't want to be just putting it down the drain!

                        UV cure it and then filter off the solids through a coffee filter comes to mind…..

                          I think evaporation is probably less effort than the filtering.
                          I've tried the filtering idea with saturated IPA- now THAT'S a faff!

                            My tuppence worth if I may...I had the chance to get my brother-in-laws very cheap when he upgraded. A Voxelab Aries. Decent beginner model, comes already built, easy enough to use, incredibly difficult to master!
                            I have however made some equipment for my modelling, from freely available files.
                            The paint carousel in particular is such a space saver and extra levels can be added easily. Also some bottle holders to help keep workspace just that bit more organised. These can also easily be scaled up/down according to bottle sizes.
                            TinkerCad is a great free program and fairly easy to get a grip of for simple designs you can do yourself.
                            I've also printed off some 1/35 accessories, ammo boxes, fuel cans, weapons boxes etc to add to my builds. I would struggle to make anything smaller as the detail would just not be there, and that's the limitation of filament printing.
                            I know it's something I'm finding useful just now but I also know I'll run out of useful things to print very quickly, at which point it'll be rarely used. I would definitely go the used route if you can, and if you decide to upgrade later then great. If it becomes an ornament then no great loss.Click image for larger version

                              Using the wrong sort of filter probably there Neil. IPA needs a hydrophobic (water hating) filter, like an oil filter, I think. You were probably using a hydrophilic (water liking) type.

                                I was using a paint filter Tim,as supplied with the printer... which do you think that would be?
