DrVax, I am new to 3D printing. I just received my ender 3 pro one day ago. what I am about to say(if you read this) I have never said to another man. I love you, yes , I said it. Your video's are amazing. I love the knowledge and kindness you present to us that helps those of us, who grew up in a different time, to continue to learn. Thank you my friend.
I just found the term ultrasonic cutter that a Chinese manufacturer suggested not your bare hands for cutting 3D printed parts! I am assuming an ultrasonic cutter would be a motorized mini Exacto knife so when you cut 3D printed parts it doesn't take much and you cut right through the support. I have quite a few printed parts in my plastic modelling hobby something I never considered how to clean up the parts. There is actually now products that don't need cleanup at all and done for you by the manufacturer which is best. Very helpful thank you!
I thought I would use my hot knife a lot but in fact I use a side cutter more often and only use the hot knife for very small hard to reach cuts and cleanup.
I've been so engrossed this past year, trying to print these certain geometric shaped for this project I'm doing. Your tip about the ironing could very well solve a lot of the problems! Cheers, Dr Vax!
Have you ever tried a ultrasonic knife (sonic knife, sonic blade)? IMHO the best way to clean delicate structures without the danger of overheating / melting the adjacent areas.
I use tough gloves whenever I use a knife to clean up a model because you may think you're smart with a knife, but there are usually very strange angles that you need to cut at. It's not like carving away at a stick where you can easily point the knife away from you.
Thank you so much, I 3D printed for the first time to get a custom sized item I needed for my garden & was very unsure about how to clean it up without affecting the integrity. You made this so easy to understand & I feel confident now that I won't destroy it. I may or may not have childishly made it glow in the dark when I saw the option, 100% unnecessary and 100% worth it 😂
Very interesting video, the hot knife looks interesting. However, bit confused about temp range? You say yours goes down to very low temps - sub 100c. I cannot find any that go lower than 180c, most are 200c. Looking at yours, it looks like a Fuyit tool that I see on Amazon UK (+/-5c up/down buttons, digital display)? That one appears to go down to 180c? I guess though, that if one puts the Exacto type blade attachment on, which you used at one point, thermal gradient on the thin blade will mean the tip is a lot lower in reality. I do have an Antex thermostatic soldering iron that goes down to 200c. I'm wondering if Antex do other tips than soldering tips. Might look around.
Great video, I have the cross hatch layer that was from the support that is in a tight area, any advise for this. I don't want to use heat because it might damage the print (not surgeon hands here)
The link for the hot knife you used is dead.. I have been looking around amazon but it seems like the one closest to what you used starts at 300 degrees.. you said you can turn yours to 90 degrees. What model do you have?
This is the "woodburning kit" I purchased "46pcs Wood Burning Kit Creative Woodburner Set with Adjustable Temperature Soldering Pyrography Wood Burning Pen, Embossing/Carving/Soldering Tips". You can use any "solder iron" with an adjustable temperature that can use "knife style" tips. You want the iron to be able to go as low as the glass transition temperature of your filament. So for PLA this would be about 50 - 60C or 122 to 150f. Here is an Amazon search for the right thing. This is an affiliate link -- it helps support the channel -- at no cost to you. amzn.to/2PmNbCL Hope this helps. Irv
This helped me so much! I bought this pyrography tool that was great (for wood...) with alot of nibs, 30 watts and around 400+ degrees maximum. Just as you said it would miscolor all lighter coloured PLA. Also, it would give off a strong sweetish smell of burned plastic. I've looked so much for a guide on what WATT results in what heat but it seems impossible. Now I ordered one that can switch between 7 and 15 watts. Should be low enough.
I am away from my computer now. I will update the link tomorrow. Thanks for pointing this out. Basically any “wood burning” iron with a blade will work.
You dont need print so much big raft .. There is distances .You can print only 1 mm around object .No 5 cm :P Unless you are using a raft to support a tall object .
Thanks for sharing. Yes you are able to use a smaller raft, but if the purpose of the raft is to support an object with limited contact with the print surface I find a larger raft is more reliable. I do not spending a bit more time printing the raft to limited the possibility of a failed print.
wow this video is fantastic, it gave me a wealth of information, I never considered using my hot knife in this fashion such a great tip thank you for making this video
I use Crystal Glass nail file. First I file roughly without water and then to get a smooth surface with water and light pressure. I have used it on PLA, PETG and ABS and it has worked well on all
Thanks for the comment. I will give it a try. I will be doing an updated video about finishing 3d prints in the future as a number of new techniques are available.
I suggest you to position camera at the bottom face of the surface that you were smoothening and at the top surace from you were scratching off the left outs of support. I could only see you operating the tool and not what it does to the surface.
I was hoping this video he mentioned how he printed the blue infinity cube (with or without support, what angle, how to clean up, etc.). Was a bit disappointed to see it on the table and having him not talked about it...
I just switched to using kit.co for my links. I still need to find all the links in my older videos. This will take you to working links: kit.co/search?term=drvax
For cleaning up prints instead of a knife or a hot knife/foam cutter i use a scraper made by the company MiNi they makes the TS-100/80 soldering irons. Its called a Viper scraper. Its made from damascus steel, is pretty AF and i use it for everything. Even taking prints off the bed. Its one solid piece of metal and comes with a ruby oxide whetstone. I can get it near razor sharp. Just don't drop the thing blade down. It takes forever to hone the ding out of the blade
For removing supports I use a temperature controlled soldering iron which has all the attachment tips, works perfect. I think it's worth investing in premium tools that will benefit my hobby in the long run. Even heating a hobby knife blade over a candle will do the trick nicely if worried about melting or burning a print, I tend to go slowly especially when working with delicate prints. Great video.

Really helpful thanks
Brilliant tip about the hot knife, cheers Dr Vax!
Thanks. It does make life easier. You just need to get the temperature right. Make sure you buy one with an adjustable temperature.

I would love to try one but they seem quite expensive.
Great info!
thank you for the tip, where can I get that Hot Knife?
Pick any “hot knife” on Amazon
I wish I had him for a teacher in school would have made it so much easier.
Thanks.
if u want a bevel on the edge bevel it in the model before printing it

Glow in the dark sounds cool and doesn't effect anything in a negative way so why not? You made the right choice, am sure it's cool happy😄

@@bryanpanton Amazon.
@@zvbxrpl doesn't have a model, just described as a Fuyit wood burning pen kit.
The link to "Adjustable Temperature Hot Knife" is not found anymore
Is there anything to stop the plastic to stick to knife or soldering iron or doesn't it tend to stick?
I am new and researching 3d printing you vidio has taught me so much your videos are very informative and helpful so thank you so much.
as soon as you took that heat gun to those towers... like watching a horror film... don't go in there! :) good times.
You are absolutely correct. Do not use a heat gun with finely detailed features. However, for a lot of heavier prints, it works great.
Great video, I have the cross hatch layer that was from the support that is in a tight area, any advise for this. I don't want to use heat because it might damage the print (not surgeon hands here)
your link for purchasing an adjustable temperature hot knife is no longer valid. Please specify the name and model of the knife that you are using.
Super good advice and I especially love the use of the hot knife. I have to get one for myself :) thanks and greetings nicklas
Thanks for the comment.
What hot knife do you have / recommend?
Great video! I'm new to 3D printing. This info is just what I needed. God bless.
Butter and cake, thanks now I'm hungry. Nevertheless very good video just like all of them.

Thank you for making this video. Very useful information.

How do you clean those small litte spidey webs on cookie cutters?

How do I remove stuck support on the bottom of the 3D print?
Thanks for the hot knife tip. It should definitely help with removing those pesky support marks underneath my prints.
Hello Doc,
many thanks for your great videos! Can you please update the Amazon link to the hot knife, it does not work anymore. Greetings, Ralf.
I am away from my computer now. I will update the link tomorrow. Thanks for pointing this out. Basically any “wood burning” iron with a blade will
work.
What is the make and model of the hot knife. That link isn't working.
Do you know if the hot knife can be used on PLA wood filament?
I love your videos btw, very helpful!
Don't see why not. Just keep the temperature low enough so the wood does not burn.
@@MakeWithTech thank you a bunch for replying, and so quickly!
Great info. I like the info and pace of your videos. Thanks Doctor - from a hobbyist newbie and my demanding toddlers.
I'm off to buy a hot knife. Thanks 😊
Hello what is the brand of hot knife you are using ?
Thank for these solutions, very helpful for me :)
Great video! Thank you!👏🏾
Great video. What is the make and model of the hot knife you are using? Where to buy?
I’d like to know that too. Your link doesn’t work and I can’t find one with a low enough temperature on Amazon.
nice tips.. that hot knife will gonna be useful tools for cleanup the pla thank’s for the tips👍🏻

I can never seem to get the raft off.
Try and avoid using a raft whenever you can, they're a pain in the butt. A brim or skirt comes off easier and select support as "touching buildplate"

hi, nice video, i am picking up a hot knife kit. i was wondering, what is the magnifying tool with the clips called that you have on your bench
i really like the solder station with the mag glass. Could you give me a link?
Thanks
Good tips! I just used the amazon link to try the wood burner, I have a small 3D printing business and I think it will help a lot, thanks

Yep. One of my early videos. The hot knife trick does work great.
DrVax i haven’t used hot knife i have a small mini drill kind of thing tiny one and i just use sand paper it works perfectly for me
LOVE the (LEARN SOMETHING TOGETHER)
What brand and model hot knife you using in the video?
Awesome! Great pragmatic how to advice
Thanks. Just be careful with the heat gun :-)
zoom in please, we don't need to see your entire office and degree on the wall - just close up of what you are doing
