How to Prepare and Prime 3D Printed Parts for Painting - My methods

[@herllraiser6662]

Ive been spray custom painting over 30 years, with rattle cans pop them in hot water, you need your area to be at least 21° for the thinner to evaporate. Popping the cans in hot water warms the paint, as you spray it gets cool, which in turn cools the paint, so warm cans you get better flow and the thinner evaporate alot quicker, which stops the crinkle effect. The spots you are seeing are known as fish eyes this cause by any thing from dust which has any wax or silicon in it, so if you do have a paint area dont have any silicon products in the area or on your hands, but if you do get fish eyes get a small brush wait till the paint has flashed off (gone dull) then paint some more paint in the fish eye, sometimes this works but sometimes you need to move the brush with the paint like small scrubbing motion, leave it to flash off again then recoat as normal repeat if the fish eyes come back..but if you wash down your part with panel wipe before hand you souldnt get fish eyes, also use tack rags they help pick up any dust on you item, these too work better if warm, But hotter your paint area is the better it is with rattle cans, i use 2 pack paint which need a harder to go off, getting a glass finish with that is super easy but you are talking more money and equipment.

Hey guys, I'm a residential painter looking to 3d print and paint as a hobby! This was a great place to start for learning tips and tricks, Thanks! Painting tips- if your project has a paint run/drip (ive been spraying for 5+ YEARS and it still happens), use a dry rag and dab the excess paint. WAY easier to sand down and most of the time just fills up with a touch up spray of primer lol Also, heat your paint cans up by leaving them in hot/warm water for a few mins.. gives an easier spray and better finish!

[@fakermakerprops3948]

I've been making props for about a year, starting with cardboard, then I got into foam, and in March I 3d printed a mask. I put probably 15 heavy coats of filler primer and then sanded it with 220 after that. It really hid a lot, and gummed up the details.i think it is still great, but filler primer is powerful Edit: I'm at megacon right now and Adam Savage himself signed it and said that it was amazing so it can't be too bad!

[@thewitchofsloth]

Dude, awesome!!

[@DaddyScribbles]

As an industrial designer I've done a lot of model making and this video is so valuable in terms of the tips given. 🙌

[@PaxDrakonis]

This was a great refresher and exactly what I needed for a point in the right direction. Thanks for taking the time to make it! PS: Florescent lighting naturally strobes at the frequency of your A/C power (60hz for NA, 50hz for EU) so depending on your camera it can be very difficult to get rid of the strobing effect in video because the effect is caused by your frame rate not being in sync with your A/C power switching frequency. The easiest way to eliminate this without expensive studio lights is only use either incandescent or LED light sources.

[@FranklyBuilt]

No problem! And they ARE led lights lol

[@RevJimmy69]

Another awesome practical demonstration using real life examples from low detail to high and eplaining the do's/don'ts along with pros and cons of each primer and the benefits of good pre-sanding. I watched this vid after your sanding one, which was great too. Thank you for sharing your knowledge.

[@hawkskyflier]

Just starting to paint PLA plastic printed models.. found your side.. The round dots you are referring to at 26:30 ... in the auto industry... are called "Fish Eye's". Those are from contaminants on the item being painted. Your are correct, your oil on your hands most likely caused this. Best to clean each item before painting with some rubbing alcohol or something that will not attack the plastic, but will, however, clean all the impureties on the item... Thanks for explaining so well, how to do this and products... Cheers!!!

[@FranklyBuilt]

Hey thanks! No idea it ever had a name haha but always knew it’s 100% user error lol 😂

[@techsavvyhero]

Thanks for putting the time into making this method rundown of priming. Helps a lot! Cheers

[@WhiteRaven___]

Fyi, the strobing effect in the paint booth is probably coming from your overhead lights. I assume LED? You can try changing your shutter speed on your camera to 1/50s since you are in London right ? Or 1/60s if your in US. You can download a 3rd party camera app if you use your phone to record. Open camera on android works well If you use android. Good video though!

[@JoshuaHaasua]

Literally was thinking about this type of video the other day! Thanks! Video quality is getting so good!

[@Mulready101]

currently building the mark VI, watching all your vids for info and inspiration. Great work!

[@benibarra23]

Add acetone to your bondo spot putty and apply with a paint brush. Makes it go on smoother, easier and covers those small detail parts you were taking about.

[@arielperez628]

just a small tip, wetting the floor if youre in a shop helps keep the dust down, we use to do that in a bodyshop without a booth lol

[@alkalinecobra666]

Glazing putty is great for filling deeper layer lines or places where supports have been removed from.

[@briandicinti9535]

I agree and nice thing about using Bondo 1 part glazing putty over the primer is that it is laquer based and eats into and bonds with the primer and super easy to sand as opposed to Regular Bondo which is so much harder than the paint. I use the Rustoleum auto laquer primer he used second and the bongo 1 part glazing putty which work great together but have also used it in the Rustoleum filler primer as well which I believe is enamel but don’t quote me on it.

[@staven]

Great video! Very informative frankly. Keep it up man! Probably want to fix the strobing lights in the video..

[@LondoBell82]

Your page has helped me a lot thanks a bunch. I also find for the panel lines that get lost in the filler primer, I just use my gunpla panel line blade. Works wonders.

[@IMChrisThom]

Since this vid is 3 years old are there any things that you would update in regards to how you do them now vs then? Or are things just the same?

[@gettingfitat5015]

Dude! You sand FAST! HAHA!! That is an EXCELLENY review of all the different primers. I've always gone to the filler primer, because my sanding skills are severly lacking! Just gotta keep practicing! :-)

[@ayoomon1604]

I like the noise when you fast forwarded the sanding part.

[@FranklyBuilt]

Me too! Haha

[@Steve-gi2yj]

sorry I know this is an old video, but wondering, I have a little bit of lines on my prints, wondering if I should just really sand it down, or did the primer of one of these would you recommend best to get those lines gone or just rely on sanding? i will of course sand, but want to see if clearly which primer worked best? i am backing a star wars armor... and need to make sure the lines are gone.

[@Slomo-kj7yx]

Do you sand again after you prime

[@joshaklese4969]

That Plastic Primer chemically bonds to plastic surfaces. As I understand it, the primer will etch itself to the surface. It's hard to find these days though because Rusto created a hybrid line.(2X) Then they eliminated classic rusto and the plastic lines. But 2x line is an easy go to for most situations.

[@hubbada6373]

4:38 nice dexter reference you got there haha

[@DomOfPrints]

Just curious, I’ve been getting more into the 3d printing hobby and i was wondering if i should paint or prime first

For the smoothing process. Can you use the wood filler for smaller prints? I’m doing a little model, about the size of a baseball. And it has a few crevasses and intricate details in a few spots

[@Sal_Sal27]

If you don't mind, I have the 2X primer and I'm looking to sand with 400 grit. Is the 2X good for that or should I get the Filler Primer?

[@AustinBeaty726]

When your done sanding what do you clean off your print with before primer?

In DIY car paint booths we used a tub of water inside the booth. Think it helps with dust.

[@mariskabuurlage4584]

If you have applied the last layer of primer, do you still sand it? Or do you leave that last layer and go straight to the paint job? Thanks!

[@ThaiRoney]

Sand the last layer of primer so you get mechanical Adhesion you the paint. Sand the primer with 400 grit or higher

Just cloth

So if I have oils on my prints from hands, what would you wipe all the parts with before priming? Also loved the video

@@FranklyBuilt Okay I will look a little bit harder through your videos for it. :) would you say the plastic primer was worth it in the end? or stick with the black sand-able primer.

[@johansrk]

Do you wash your print before painting, of just wipe away dust from sanding ?

[@apdp15]

@FranklyBuilt So I just got a 3d printer and I printed a Mandalorian Vambrace and I am not sure if I should sand down the layer lines so that you can’t see them or if I should just leave the layer lines alone. What do you think?

[@peebs2424]

After sanding do you clean the plastic with iso before priming?

[@samuelrosario570]

Hi there! One question. That plastic primer is the same as plasty dip? Or m I just ultra wrong about it? Best regards, sam.

No haha plastic primer is primer Spraypaint. Plasti-dip is a sorayable peelable rubber. Worlds different
