But could you print a kit? Of course, there would be quite some work to turn a model into a multiple-models kit, but it would be there anyway.
The problem with other techniques is that you need a big initial cost (the mould, for example), so it is interesting only if you have a big run.
Export your base object model as stl file, pretty simple. I’m sure the model is made up of many parts however which is likely what you’re talking about in the sense of difficulty.
If it’s all in one large model project then most 3d programs let you merge and export those pretty easily, if their seperate then yes the problem exists in getting all those models together (not major ordeal but still time consuming).
@ThornEel I really don’t understand the purpose of a kit. Its a simple model mate, what exactly would you glue together? and how would that equal better quality model? think about it for a bit
The difference between 3d printed models and plastic injection molds is HUGE. Plastic injection molds allow for rediculous detail, most 3d printing doesn’t even allow for smooth surfaces. But I’m sure 3d printing will someday be as good as injection molds.
Agreed. I have a bit of experience prepping models for 3D printing (Both CAD files and polygonal meshes), CAD files are way easier than polygonal to get prepped for 3D printing. I’ve also always been very disappointed in the 3D print quality.
I grew up making a lot of 1:48 scale aircraft models and that’s the kind of detail I really want in 3D printing someday.
Most people print at 0.2 resolution, you can go down to 40 microns with some printers but that resolution is only in the horizontal, most still only have a vertical 0.4mm nozzle.
The thing is you can go get yourself a 0.1 or 0.05 nozzle and make smooth surface prints but the print time is astronomical (takes ages to get working right also), we are talking DAYS here to print something at that resolution. It’s going to take a fair bit of time before 3D printers are fast enough to print those resolutions in a reasonable time frame.
You should however check out some prints done correctly (aligned so highest resolution is shown on outside of model) with 100 or 50 micron resolution, they are quite good and if you want mold quality you can expose them to acetone vapour for a short while or use a 3d model resin paint.
For on shelf models I think that is pretty good atm, but majority of 3d printed objects just don’t need to be ultra quality for their function.
doesn’t work like a inkjet printer just yet, maybe one day. But when you think about it, plastic doesn’t quite flow like ink. I think maybe if they make a printer that takes 0.5 sized filament then something could be done with speeding printing up because atm if you attempt to go too fast it oozes out too much and just simply makes a mess.
