How to Paint 3D Prints

Sharing buttons:

hey guys hope you all doing well hope

you had an awesome Christmas I know I

did I basically just say a load of food

and just took a bit of a break and it is

nice to get a break from your usual

routine but today I'm back again with

another video and I thought it'd be a

good idea this time to show you how to

paint your 3d prints I've been meaning

to do this one for a while and seeing as

this Christmas I thought why not

download a Santa STL model and paint

that one so I'll leave a link to the

model below if you're interested but I'm

going to show you how I printed it how I

painted it and just give you some tips

that I like to use when I'm painting my

prints and I know X but after all a

painting so if you've got any tips for

me please leave them below I'd really

appreciate that but yeah let's get

straight into the video




okay so at this point we want to be

prepping our print ready to paint and

poly filler is one of the things you can

use to fill in any gaps or holes that

may be in your print and also we can use

some sandpaper as well if you're

printing something flat to really smooth

down the surface and ultimately the

smoother the surface the better the

paint is going to look as you can see on

a previous project I had to really

smooth out that top layer because when

you apply paint to it you can see the

lines quite clearly so it's best to

smooth it out as much as you can and

again you can use poly filler to fill in

any of those gaps this however is a

little more tricky when working with

something like the sander model because

it's quite a complex shape and has a lot

of round edges this isn't really an

issue because 3d printers today tend to

print curves really well especially if

you use a low layer height one other

thing I recommend you do is use a primer

or a filler primer and this is basically

a first layer of paint before you get

colorful so this creates a better key

for your acrylic paint to stick to when

it comes to adding color typically 3d

printing plastic doesn't take paint that

well but what this does is it allows you

to fill in those gaps between the layer

heights but also having a better key for

your paint to stick to and you can apply

as many coats of this as you want I only

did one but the more you apply it does

tend to smooth it off just remember

don't spray too close or the paint will

start of run you want to aim to

distribute the paint evenly from

multiple different angles when

spray-painting it's important not to

touch wherever you're trying to paint so

one little hack I like to use is a bit

of electrical tape and a block of wood

and what you can do is just use the

electrical tape and stick it on the

underside of whatever you're painting

that way you can hold onto the block of

wood while you're spray-painting the

actual model if you're after a super

smooth finish you can even send the

primer with a very fine sandpaper I also

did this on the previous project and it

basically just gives you the smoothest

finish possible ready for painting and

it's especially useful if you plan to go

on and use some kind of clear gloss to

give your model that nice finish so

after applying one layer of primer we're

now ready to go on and add some color to

our model and to do this I'm gonna be

using some basic acrylic paints I had

these ones in

from Amazon worth mentioning that the

quality of the paints you use will

ultimately affect the final outcome so

you might want to invest in a good set

of paints these ones were quite cheap

and I still managed to get some

reasonably good results okay so this is

where hey you actually start painting

and this requires a lot of patience I

like to listen to an audio book or a

podcast and it really kind of gets you

into it I would just recommend that you

take your time and do it in multiple

sittings you know if you try and rush it

or you get a bit of stressed out it's

probably going to end up being ruined

and you have to go back to square one

so just take your time I'm gonna roll

some music again so you can watch it

we'll see what it looks like at the end


so here's the result directly after

applying the acrylic paint and it

actually looks pretty good there's a

couple of brushstrokes so you can see

but there's a great way to eliminate

that and this goes on to the next step

so the next thing I'd recommend you do

is apply a sealer so this stops the

paint from coming off when you touch it

and also it provides a really nice matte

finish and this is what it looks like

after I've applied that matte finish and

you can see it really flattens you know

and it does get rid of a lot of those

brushstrokes that you can see from

earlier on so that's it for this one I

hope you found it useful if you did
