Airbrush or traditional painting when coloring prints?
Airbrush or traditional painting when coloring prints?
Since I got back into 3D printing I really want to fix up my prints now with sanding and coloring. Would airbrushing or traditional painting (paint brush) be better?
Depends on the size and shape of what you want to print. I print mostly miniatures so for me while it would be nice to have an airbrush for doing primer, zenithal coats or other shadows, and base colour, I would still need brushes so it's not really that useful. If you're printing larger things, or things that will only be one color (or that the colours are easy to mask, e.g. a cube with each side one colour) an airbrush will save you a LOT of time.
It is all about aesthetic choice and preferred workflow.
I don’t touch airbrushes. I paint everything traditionally, and I’ve done a lot of prints. I know many people use airbrushes for either speed or just because they prefer the look.
I can’t tell you how you like to paint. I can offer specific suggestions based on your plans. What exactly are you planning to paint? Are you doing a lot or a little? Are there time restraints?
I'm interested in doing it for figures/busts and cosplay parts
I think for cosplay, you would like an airbrush. You won't be as concerned about teeny tiny details the way a miniature painter will be, and airbrushes can allow you to do large areas with even coverage and easily and quickly make gradients.
For miniature figures, it is a much more taste based consideration, but if you're already getting the airbrush for cosplay you may as well use it on figures in some capacity.
I personally avoid sanding. I use modelling epoxy to reduce layer line visibility, then I apply a coat or two of high build primer. I only sand a little bit to reduce imperfections from epoxy and primer. Then I use spray can paint and finish with a lacquer.
why do you avoid sanding?
Takes a lot of effort and it's not worth it. Fill the layer gaps with epoxy, job's done.
depends on what you're painting, and what you're looking for, really.
I like using airbrushes for coverage applications- priming, base coats, they're more even and consistent while also being very quick. It's also great for layering colors/patterns and shading. airbrushing gives an even and smooth patterns.
standard brushing can do better at fine details and creating a textured finish. they're also useful for applying washes and masks as well where airbrushing won't work, and pinstriping is a harder edge if you're not wanting to spend oodles of time masking off (with tape or paint-on rubber stuff.)
Sponging with make-up application wedges, or almost any other kind of sponge and ragging with paper towels or dishcloths or whatever are also great for applying washes and removing layers off, creating different textures and looks. It's not like there's hard rules here, so grab failed prints and experiment.
