3D printing hack - Finishing 3D prints with less sanding required | How to sand 3D prints fast!

[@billverine765]

Great method for smoothing DWD. One suggestion I have for everyone is to use a tracer coat on the primer. It takes the guess work out of low spots and pin holes. Just get red or black primer and put a dust coat on top of your last coat of filler primer. When you start to sand, any high spots will burn through the tracer coat immediately, then any low spots will stay the tracer color. This is an old body shop trick that has been around for years. It really, really helps you get a great finish and no surprises when you go to paint.

[@Darkwingdad]

Great tip as always, I’ve mentioned this is previous videos since most primers are grey any matte or flat paint/primer that’s darker on top will work. Always appreciate the pro insight!

[@secritsquirrel4994]

Time is money. And trying to optimize post-processing is so critical when it comes to finishing 3d props. Really appreciate you!

For big panels & non intricate pieces it’s ok but it often causes gouges, you can’t clean up crevices & still rely heavily on puttys & fillers.

[@toysforboysrc]

If you ever have a print that does not have a lot of fine details, you can experiment with thinning bondo with “Honey” or even yet polyester resin. You’ll want to add the same amount of hardener as you would and you’d also want to add the same amount of MEKP that you would for the amount of resin added. Then brush it on very generously and it will self level. Pinhole from thermo runoff of drying too fast or not at all is all practice. The ICING bondo glaze DOES crack it too thickly applied, even if it was in separate applications bcs it does not have enough solids but that’s to make it easy to sand. I used to make my personal mixture when I used to build custom interiors and the job ever came back for any repairs or failures.

[@UncleJessy]

Oh man I’m going to order some of that!

[@vinnyboombots8270]

Have you tried adding water to wood filler like the spot putty method? I do it quite a bit, it sands super easy and has no odor except for the normal wood putty smell. It works great on filling seams at a little thicker consistency. I'll also put wood putty on seams and other hard to fill areas and smooth it with a brush and water. Works great. You should give it a try if you haven't yet. Love your videos DW, keep em coming

[@Darkwingdad]

Wood putty is water based so you can add water to it. This however isn’t, so adding water to it will simply make volatile agents less stable & cause adverse reactions. IPA is the other option but acetone works by far the best.

[@daveghahn290]

I think darkwing thinks you were asking adding water to the upol. I was thinking if trying this method with woodfiller and water as well. your comment is encouraging, I will try it tonite w. both water based silica and acrylic.

[@txwombat7826]

Thanks for the Vid - I'll be ready to give this a try shortly...

Tried this and it came out pretty great. I didn’t use UPOL Dolphin putty. I tried Kombo Putty which was supposed to be similar but I did see some tiny cracks so I ordered the Dolphin putty. Just gotta wait a week or so for it to be delivered.

[@dugabomber5993]

On the 1rst layer I recommend going perpendicular with your layer lines. Going parallel can let the brush fall in between the lines. Thanks for the video.

With this method the second coat reactivates it and works it in but going with the grain can definitely be beneficial, thanks for the input on that.

[@KylejvT]

You can smooth PLA glass smooth by using acetone as a heat transfer. It takes seconds though you need a bit more setup then when smoothing abs with acetone due to the differences. I can go through the steps to do it if interested.

[@Darkwingdad]

I am familiar with vapor smoothing with acetone. It’s ok but it often tends to lose definition & I think for most people it’s something they don’t really want to mess with. I’m personally not a fan of it but to each thee own. I can get pieces smooth so fast using this method I prefer doing this over anything.

Just make sure it's 100% sealed with laqure after your base coat! Being acrylic anything that touches it acetone, water ipa etc without ot sealed in it will reactivate and go soft and you could get a finger dint or print in it! I work with this stuff everyday it's grast for time and dry time but it jisy doesn't have that total curing mind at ease rigidity you'll find this with stuff if your making masks etc and wearing them out like some do with iron man masks haha!

[@dustinroberson1865]

I apologize if this is a dumb question, but what benefit do you gain from using the glazing putty before filler primer? Does it just do a better job of filling the slightly bigger imperfections and layer lines? I found that if I sand the really bad layer lines, then put a thick coat of filler primer on, sand with 400 grit after dry, then put another coat of filler on and sand again, most of the issues are resolved.

[@Darkwingdad]

@@dustinroberson1865 less sanding, faster turnaround & fills in imperfections faster. Filler primer is great but it’s not a 1 & done method. If that’s all your using you’re wasting time & over sanding the model.

Or you could use upol reface if you can use a paint gun. It's thin sprayable body filler. If you do it right the only sanding you would need to do is roughing up the surface for the reface to stick and a light sand for primer/ paint to stick to the reface

[@Darkwingdad]

Except people may not have a place to put a compressor. Or an hvlp gun, or a place to spray it. Or clean it up, or just the time it take set up,clean up etc. and the cost! Reface,slicksand,featherfill are all over $130 for a gallon. Trust me I’ve used/use them they are great products but there are more cons than pros the using sprayable body fillers for most builders. This method is light years faster & way more efficient.

[@monster_eh3938]

I have a friend who works at a bodyshop and gave me a big pouch of U-pol Dolphine glaze UPO714 ultra fine finishing glaze would it work the same just don't add the hardener or would I still have to add it

[@Darkwingdad]

No it still needs the hardener. You can add a filler honey to it to make it thinner but it’s not quite the same as this. It is a great filler for gaps & deep imperfections.

[@OliWright]

Have you tried this with ABS? I'm curious whether the acetone thinning would just wreck the plastic, or result in a better bond.

[@Darkwingdad]

The only way acetone will damage pla,petg or abs is if you suffocate the model or engulf the piece in a vat of acetone. In this method it evaporates so quick no damage will occur. Bondo putty & all aerosols contain thinners & acetone too, they don’t damage the plastics & niether will this. Your safe :)

Hey have you tried automotive glazes? U-pol makes dolphin glaze and gold glaze(lighter weight?), and a dolphin speed glaze you can sand in 6-8 minutes. The TDS says they have the same or more solids than regular dolphin or the 1k, so they don't just have more thinner? I wondered how well they would self level. You have probably researched this with your recent videos, but it is new to me.

[@Darkwingdad]

Those require hardeners, and although they are good for big flat panels they are still fillers at heart & take more effort to sand. I am a upol fan though, they make great products

[@lauriecrabb1461]

I'm interested in trying this, but I am wondering if another thinner, such as mineral spirits, could be used instead? I print a lot of my cosplay pieces in ASA and I don't want the acetone to dissolve the material.

[@Darkwingdad]

Mineral spirits will not work. That only works on petroleum based products. Understand acetone is already in primers & puttys, it evaporates rapidly, the same as if you were applying an aerosol. It will 100% not eat away at asa or other plastics unless you soaked it in a vat of acetone. Huge misconception people have of acetone, it’s in everything we already use, a-ok to use this method.

Gonna give this a try. Would this method be safe to use on ABS prints, since u are using acetone as thinning agent?

[@Darkwingdad]

Perfectly fine on abs. It will only effect abs & warp it if you suffocate it in acetone. When people use the acetone in a vat or container understand it’s constantly being exposed to vapors. This method the acetone evaporates in 30 seconds to a minute. No harm will be done bc acetone evaporates so quickly. Same thing with primers, primers & paint contain acetone & thinners which do not effect the abs bc it gases & evaporates so quickly.

[@clorpe]

Are we not allowed to wet sand anymore when using this product since I saw in the comments, when it comes into contact with certain liquids it can go soft?

[@Darkwingdad]

There’s no reason you should ever wetsand putty. There’s literally no reason for it & it’s a waste of time. Sanding this with 320/400 will leave it perfectly smooth & a filler primer will fill in any minor sanding imperfections. The only time you should wetsand is A) your primer before paint if it feels rough or b) clear coat to remove orange peel

[@fluxcapacitor]

"3D Printed Props" sprays a coat of filler primer first _before_ brushing the prop with glazing putty (he also applies another coat of filler primer afterwards). Would you recommend this step (1st coat of filler primer over the sanded PLA) too or advise against it, and why? Because I see here that you start directly by brushing the thinned putty over the sanded PLA, and spray the filler primer later on only.

[@Darkwingdad]

Doing a coat of primer first to me is pointless. Regardless the print has layer lines and defects that need filling in which putty will do substantially better off the bat. I personally never have done that nor will I. HOWEVER, applying thinned putty on top of primer after a round or two of sanding/priming on heavily affected areas is a method I use.

[@Darkwingdad]

A tac cloth, I can link it if you need to

[@KEVlNSU]

@@Darkwingdad Thank you! I think i have some of that laying around :) Have a great day

[@KRGraphicsCG]

This would have been great to use on my engineering prototype and just sand it at 400 grit... I wish they had a clear version of this so I don't need to paint the model (example: Black ABS) and it would be smooth.

[@Darkwingdad]

Ever think of epoxy or clear resin (not sla)

[@KRGraphicsCG]

@@Darkwingdad I do have some XTC-3D epoxy from Smooth-On, but I've never thinned it with acetone and it unfortunately has a 5-7 minute pot life. Also, it alters the fit tolerances

[@Darkwingdad]

@@KRGraphicsCG don’t use xtc look into acrylic resins that might work for ya

[@KRGraphicsCG]

@@Darkwingdad I will have to look into acrylic resins that allow me to smooth it onto a part and sand it easily. Just need to ensure it's clear. I actually stopped using XTC because of the dry time and difficulty with sanding

[@philipjensen6442]

Will this stretch with the 2:1 ratio? Or would you say you would run through this fairly quickly with helmets? Great video btw

[@Darkwingdad]

You can do 3-4 helmets with a tube no problem

[@chazhaze3d]

this is a little bit of a bed question. I can make these pieces and they are smooth all over but where it attaches to the bed. I get a very textured bottom which ruins it compared to how smooth i can get the sides and top. You have any suggestions?

[@Darkwingdad]

Sounds like a leveling issue, what printer?

[@chazhaze3d]

@Darkwingdad well it just looks like the textured bed. It's an Anycubic Kobra 2 Max

[@Darkwingdad]

@@chazhaze3d glass bed or pei plate?

[@chazhaze3d]

@@Darkwingdad pei

Where do you buy UPol 1k putty?

[@Darkwingdad]

Amazon

[@Emtbtoday]

Pretty much the same as every acrylic based putty in the scale model market I use! The enamel based one is great with IPA it works the same sort of way water would also work the same probably better if it's full acrylic based putty acetone is something I'd use last IPA would be better for the plastic than acetone, Dulux materials acrylic putty is the best on the market bar non every modelers go to really

[@Darkwingdad]

IPA doesn’t dilute this as prominently & there’s absolutely no reason to think the acetone is going to affect thermo plastics in small amounts. Acetone is already in numerous puttys along with thinner. Both are in primers & paints & have no adverse affects due to rapid evaporation rates.

[@NK_Customs]

@@Darkwingdad I wouldn't recommend using acetone in combinations with ABS, as ABS can be dissolved in Acetone, Just like those "smoothing vapor chamber" for ABS 3D prints. And indeed, both are being used in paints, adhesives, etc. without issue's ;-)

[@Darkwingdad]

@@NK_Customs total different when you are suffocating the model in acetone vs it evaporating in seconds with whats shown here. I’ve tested pla,petg & abs & there’s no issues. Remember, acetones,ketones & lacquer are all in aerosols & primers, so saying not to use this method is like saying don’t use spray paints. Any plastic you leave in a vat of acetone or vapor smooth it with no escape from it it’ll damage. But as stated this dries & evaporates in seconds. No issues here.

[@darren990]

nice

[@karenpalsdottir5935]

Is this unsafe inside the house? I just used bando putty and wore a mask but it is stinking up my entire house even though i did it in the window sill with a open window. I feel bad for my pets

[@Darkwingdad]

Definitely do not want to use these products indoors & without a respirator. Always use in a shop or outside with good circulation

[@daynafost]

Can it be done with an airbrush if you use it a little thinner?

[@Darkwingdad]

Yes it can make sure your airbrush is .8 & you’ll be fine

[@daynafost]

@@Darkwingdad thanks I will try it.

[@Darkwingdad]

@@daynafost let me know how it goes!

[@daynafost]

@@Darkwingdad will do. Your settings for pla works great for my pla carbon fiber, thanks

Right here! amzn.to/4anwcoq

NOICE.

[@SuperDuperTango]

Are you still recommending this product these days? Also, what are your thoughts about spraying this like your videos about spraying the bondo putty? Thanks!

[@Darkwingdad]

Yes dolphin 1k is superior to ANY putty out there & it’s sprayable. Doing a video on that too

[@SuperDuperTango]

@@Darkwingdad Sweet! Thanks!

[@chrisjhart]

Can this be wet sanded? When I've used acrylic fillers before they tend to lift the second you try to wet sand. Great video, thanks :)

[@Darkwingdad]

You don’t need to wetsand any filler or putty nor should you. Only time you should be wetsanding is after your final primer before paint & after clear coat to reduce orange peel.

[@chrisjhart]

@@Darkwingdad I mainly wet sand so it stops dust. Works really well

[@Darkwingdad]

@@chrisjhart understand you are introducing a solute which can prolong curing & affect adhesion with top coats. I don’t recommend wetsanding puttys

[@chrisjhart]

We are going to have to agree to disagree on that one. The only real purpose of wet sanding is to provide a lubricant so it doesn't cut as roughly. I've a whole packet of the stuff ranging from 400 to 1200. I always wet sand where I can for the reason that you are not putting harmful dust into your work atomsphere. Yes, with acrylic it tends to delaminate it, but everything else is good to go in my experience.

[@Darkwingdad]

@@chrisjhart to each there own but you did express issues when you wetsanded & I explained why it’s happening-your adding excessive & reactant solute to the substrate. Following automotive body repair (which are all the products I use & demonstrate with) wetsanding isn’t recommended or used. Dust is something you have to deal with, that’s what ppe is for. I’ve had zero issues pyramiding my grits dry, the dust I just deal with 🤷🏻‍♂️ I’m just demonstrating what professionals used & have used in automotive restoration & what works in my methods. There’s methods & products that others use that I never would, at the end of the day I guess if it’s working for you roll with it. Difference of opinions are like hairs in your head, & unless your bald theres too many to count.

[@mental_r0bot459]

could I use this technique with dap wood fill?

[@Darkwingdad]

No, do not use wood filler at all. Harder to sand, more porous, cracks over time

[@mental_r0bot459]

dad it's all I have right now

[@Darkwingdad]

@@mental_r0bot459 go pick up some bondo glazing putty or upol fantastic putty. Significantly better products with faster dry time & less shrinking

[@jasenq6986]

is the acetone mostly for ABS?

[@Darkwingdad]

No, this isn’t acetone smoothing. The acetone dilutes the putty making it more soluble so it can be brushed on. It evaporates so fast though it dries the putty in minutes and than can be sanded.

[@triton6597]

Hey man, by any chance do you play in the adult hockey league? I’m pretty sure I ref where you play. Small world I got into making cosplay two years ago by doing a mandalorian costume and a Bo Katan costume I started 3-D printing myself a couple months ago prior to that I was buying 3-D prints at finishing them. I’ve used your videos to help with that.

[@Darkwingdad]

I do, unless your the ref with glasses I’ve never yelled at you lol glad the videos are helping. I wanted to 3D print a puck in petg and see how long it lasts….get me 10 extra minutes of ice let’s make it happen lol

[@RLCPLUMBINGLLC]

Could you spray the putty?

[@Darkwingdad]

Absolutely, I’m doing a video soon on it

[@jaytomchuk5474]

[@Darkwingdad]

Have you looked into bondo plastic metal?

[@hffb27]

Thanks for the info, you can probably edit out when say the same thing over and over.

[@Darkwingdad]

When getting a point across repetition works.

[@MarcoNoPolo]

I wonder what it looks like a year later. That putty isn't catalyzed, so I'm sure it shrank enough where the layer lines are back now.

[@Darkwingdad]

@@MarcoNoPolo it’s solvent based, plus your thinning it with a heavier solvent in acetone which accelerates curing. Got about 5 helmets of my own where I’ve used this method and 50+ for others, no issues and didn’t shrink.

[@MarcoNoPolo]

@@Darkwingdad Well that answers that question. 👍I like to use 2-part Urethane primer myself.

[@Darkwingdad]

@@MarcoNoPolo definitely a nice option, I’ve used a few including the popular featherfill & slick sand just the clean up sucks lol and not everyone has a compressor or set up to use it.
