- Welcome to another episode of Tinkerine Experiments. Today, we are going to use a sandblaster to smooth out our 3D printed prints.

Thanks, you just saved me from wasting money on a mini sand blaster, now I know it doesn't work.
Thanks for the comment! The media that we used in the experiment wasn't new but we believe if the media was new it will provide better results.
As long as the wall is thick enough, sandblasting might even be too abrasive sometimes. But you need to see what you're doing in order to get a decent affect
@@Tinkerine Looking at the results, the media was not only old, but also dirty as your prints look smudged and brownish after blasting. Would clean media still affect the color of the prints?
It could definitely make it easier to paint though
Harbor freight sells a cheap sand blaster. Also I would like to see the sand blasted parts with a coat of primer or other paint to see how that looks. Thanks for posting the test !
Thanks for the comment!
Or, buy a resin printer for the same cost.
"we can't really see whats going on in the sand blaster"
Ohh sand blasting lol definitely a love/hate relationship for me! xD
We totally understand, thanks for the comment!
Would love more information about what PSI, CFM, blasting medium you used.
I was wondering this too. Seems we will never know
Sandblasting is a fast and easy way of smoothing the lines on the prints. But only if you have the right equipment. You need a lot of air when sandblasting. Preferably a rotary screw compressor with a delivery of 900 litres/minute, at least 500 litre air tank and a good sandblasting pistol, not a 20$ walmart special. For blasting you should use a ceramic, like aluminium oxide. You could also use quartz but it creates a lot of dust so it's a lot harder to see what you are doing in the blasting tank/box.
So in theory, you can sandblast the prints to perfection, but the reality is that you will need near industrial grade equipment to do that🤷
aluminium oxide is way too abrasive on plastic, you either use plastic on plastic or soda
thanks. I was wondering if that would work.
Why on earth every adult prints a pile of useless sh*t and figures with 3d printers...? Literally every video... there's another dimension of creativity that 3d printer opens up and ppl print crystals that don't even look good 😂
Soda blasting(baking soda) will smooth but also will not leave that dirty look
Stick a rubber magnet inside and a neodymium magnet outside the sand blaster like a fish tank cleaner
You just demonstrate that it does not do (nearly) anything and with your figurine you even show us how printed layers are being ripped apart. Moreover, I can imagine that for technical parts made of resin is completely unsuitable, because dimensions change and there are deformations, not only due to the pressure of the medium blasted against the product but also because of the heat that it generates; it deforms the cured resin. In my view, for ordinary resins this is not a suitable post printing method. I print with SLA printers only but even then, blasting is not the best thing to do.
Thanks man, very good and detailled video. I was thinking to get a small sandblaster, but this is really for super fine tune post-processing, but if you really need to remove the layers, it has to be done manually.
Can you share the stl or 3d model for the crystal?
Well... come to think of it... no matter how much you sand or sand blast... layer lines are layer lines...They are part of the construction itself...
Possibly need to spend more time and with more grits to see if it really works....
Nice, little more sandblasting and 1-3 coats of filler primer, these prints could look amazing
Thanks for the comment and we totally agree! With new sand blasting medium and a couple more times, they should look great!
That filler primer works at Lowe's works great..take some time between layers. Little sanding.. it's great..but it is gummy in the sandpaper..
That would take too much time to be viable.
Ohhhh how I hate detail sanding. I don’t mind busting out a rotary or oscillating sander for large surfaces but I wish media blasting did a better job. I’ll have arthritis before I’m even 40 if I don’t find a better solution. For now I’m using polymaker PVB and a homemade IPA fogging station.
WOW!!!!! THAT IS CRAZY!!!!!!!!!!!!!! I think if you were able to use finer sand, you could get it very smooth... but a sandblaster for home.... highly unlikely.
Thanks for the comment! We quite agree with you, it is a really nice thing to have to smooth out your prints. But the sandblaster itself is not very accommodating in a home setting.
Could you just sand blast it a little longer and get a better finish ?
i think this would be great to make resin coatings bond well
Blast media matters greatly and there is a wide variety.
Can I sandblast SLA prints?
Thanks for the comment, you can definitely sandblast SLA parts too!
Dude that armoured model was so freaking clean for fdm... sadly better then some of my resin prints... what model are you running?
We are using the DittoPro 3D printer!
Would wood pla be easier to sand than regular pla?
Thanks
I wonder if it would work better with a soda blast or some other type of mixed media blast that is designed for removing paint or rust while also buffing.
use heatgun, it will restore back the color
Thanks for the comment and suggestion!
Petroleum jelly brings back the color to something my customers like
Can this method be used with SLA resin?
No. It gets too warm and deforms the product I think
Tried this 5 years ago with 'Glass Beads' and 'Garnet'. They just bounced off the print to the laughter of the PLA.
Thanks for the comment!
5 to 10 minutes of sanding?!? It's takes less than a minute on metal
Thanks for the comment! The media that we were using wasn't new so we left it in longer.
Bro metal takes forever depending what cabinets your using how much air pressure what medium and if there is paint or powder coat on it .. I do this for a living .
You didn't say what medium you were using. If it was actual 'Sand' like you were calling it then you are crazy. Sand contains silica which causes silicosis if you breathe it. Deadly !!
Thanks for the comment! We actually used glass bead but it was quite aged, and I thought we actually used sand.
@@Tinkerine What was the rating of the medium? I mean the average thickness of glass beads. What microns? Thanks..
Sounds like concern trolling
