Simple Way To Make 3D Prints Look Professional! Works For Car Parts, Cosplay, Etc!

- In this video I show you how I smooth, fill, sand, and finish 3D printed parts! This method also works for any application like car parts, 3D printed models, cosplay accessories, etc.
The post processing of 3D printed parts can be different for certain materials but this should work on most, if not all materials. In this video I am using a Nylon/Carbon material from Matterhackers. The key to this process is the Bondo glazing putty that will fill all of your low spots. The sanding stages smooth out the Bondo and eventually you are left with a very smooth surface with very few imperfections.
A few coats of buildable/sandable primer and you are ready to use these parts on your car! The process also seals the plastic from water/chemicals that you would use to wash your car.
I've had my parts installed on my car for several months now and the sun has not warped them, and water has not damaged them. This is great for one off parts that you are experimenting with!
If you have any questions, please ask in the comment section down below, I would be happy to answer them!
Thanks for watching!

#3Dprinted #Maker #DIY
I printed the diffuser wing for my kit car. 1.2M long. It’s made up of 200mm sections, designed with mortise and tenon joints on each end of each piece. Bonded together while clamped to a length of wood to keep it flat. Filled, flatted and carbon fibre dipped. It looks great (other people’s opinion) and works well to reduce the turbulence behind the car.
I like the mortise and tenon idea, do you have pictures or a video of it?
Embrace Racing. I’ve tried in the past to post pictures as a reply and failed.
That was fantastic!!
Thank you!!
Just came across your channel and love it. I get into car parts, racing, aerodynamics, and very recently 3D printing on my channel so I like your mix of videos.
Thanks! I've actually watched a bunch of your videos a while back, you do some really nice composites work!
Currently designing and printing a duck tail for my car, going pretty well so far. Definentaly going to use your video, very helpful! I'm not sure if I should vinyl wrap it or spray paint
Let me know how it turns out, would be interested in seeing it. Links / pictures!
@@EmbraceMaking will do! It’s awesome your still active in responding after 2 years!
@@minecrad9970 Did you finish it?
@@madthough2298 yes!
@@minecrad9970 How did it go? I'm going to try the same thing
Great project and video.
I'm in the middle of building a set of custom 3D Printed headlights going from halogen lights to projector and LED inspired by your Corvette series. 👌🏻
Awesome! Anywhere I can check out your work? CZcams? Instagram?
*Performing well in aerodynamics WOW LMAO just aesthetic creation bruh.*
Good job. Some excellent skills there.
Thanks Joe! Very kind of you
The instruction and worksmanship is fantastic. As I am working on similar project. But its not exactly consistent with donor vehicle design integrity. That would be my critic. But instruction value is fantastic.
Thanks!
Awesome video man, maybe paint the inside of the diffusers black and leave the outside trim silver, would look even more aggressive! Hope to see more updates on this
I had that exact idea if I thought that the silver was going to look too much! I still might try it with some plastidip so I can always go back :) Thanks for watching a few videos and all of your feedback!
@@EmbraceMaking Keep up the good work, the vids are easy to follow and are high quality
Just curious, how did that part hold up through the months/years? I also want to try 3D printing some parts. What material would you recommend for printing now?
Actually not bad, there was a little shrinkage in the thin part across the center but the big parts were fine. I sold the car a while ago so I'm not sure how it is holding up now but for a few seasons nothing seemed to have changed.
What type of material did you use for your print? This was a great info.
It would cool to see a video on how these parts are made in the software programs and into the slicer.
Thanks! In this particular print it was a nylon based material if I remember correctly. But the same process can be performed with regular PLA / PETG etc.
how do you measure the curve of the stock bumper? I was trying to figure that out but I am not too sure
Great job
Thank you Brian!
Hello great video!! I have a b8 a4 too. I want to make a part for the diffuser, can you share this part file for me to build from??
turned out really nice!
Hey man, this is awesome. So crazy how the design fits perfectly to the stock diffuser. I’m trying to print out something similar for an Audi s4 b8. Do you by any chance still have the stl file used in the video? I’m just looking for a baseline for my own design, and since I don’t have access to a 3d scanner, it would make it a whole lot easier. If not, I understand but Great Video!! Keep it up 👍
Love the video and just so happens I have the same car as you, would love to try this myself! Would you happen to have the stl file for this project?
My 3D printed diffuser is 1.2M long. Made in 8” (200mm) parts bonded together.
Nice! Would love to see it, do you have instagram?
@@EmbraceMaking. Tried Instagram, we don’t get on.
Is it possible to print all panels for a prototype vehicle
If you have a big enough printer or enough patience you could do something like that. Look up 3D printed lamborghini
Yo bro great job , one question how to measure the curvature of the bumper so that it be replicated in software?
3D scanner ;)
Those lines in the curved part are not a product of the process of 3d printing, but looks like that because of the low-poly count of the 3d model. Lines from the layers look like very thin lines
Yes, can be a bit of both really... the original file goes through several "interpretations" when converted to STL and then again to gcode and how the 3d printer controller interpolates a curve. The end result is a not so perfect curve that you can sometimes see as "low poly" as you suggest.
Fill the seam with a pen extruder using the same filament
Could work.. do pen extruders get hot enough for nylon?
@@EmbraceMaking I seen is on a youtube video on making car part.
Hey man great work, would you be interested in sharing the .stl file?
How did model the part, would love to see the process of getting a 3d model of the car to start actually modeling the part
3D scanners help ;)
@@EmbraceMaking any entry level scanners
Honestly, I've tried a bunch and most are garbage. It also largely depends on what modeling environment you are working in. I use Solidworks so scanners that only scan to STL or obj or whatever mesh type are horrible to work with in Solidworks. At this point in time, a quality scanner and capable post processing software are still beyond entry level in my opinion.
Oh and for the record, I designed this part using those mesh scanners... it was a nightmare. I spent HOURs trying to get usable data out of it... in the end it worked and I was able to do it, however, it was not something I want to repeat.
Now shrink it by about 2 layers of carbon fiber and use those prints as a mold to make carbon fiber.
That was the original plan... and I never got around to it :(
Wich material is best for car parts?
I guess that might depend on where and what you're using it for? Interior, exterior, engine bay?
Which 3d scanner did you use? Thanks!
Thanks for the video... what design program do you use? Thanks
Solidworks! What is your CAD program of choice?
@@EmbraceMaking Im have not begun yet. I think im going creality max.....still trying to figure out the program. Will look into solid works. Thank you!🙏
Very good. Is it carwash and sun heat resistant?
It was... sold the car and don't know how its doing now but it held up fine through summer and winter.
great job! how did you manage to measure the curve of the original valence on the car?
3D scanner! It was still a HUGE pain to get a good result from that and then clean up the mesh and work with it. I use Solidworks... Solidworks and meshes don't co-operate very well.
@@EmbraceMaking ahh, im thinking of using a piece of paper cut to the curve and then putting it in a paper printers scanner. Did you use photogrammetry?
fastslash25 did you try the paper method out yet? How did it turn out?
@@TheManutd9 Havent decided on the design i want to use yet, Im probably just gonna use sheet abs instead of 3d printing.
Did you have to do a 3D scan of your car before designing and printing the diffuser?
Yes otherwise it would be near impossible to get the curvature right without 1000 iterations
How have these kept up? I'm interesting in printing some parts for my Audi or atleast printing parts to use as part of a mold for fiberglassing. Just wanted to see how these have held up
Well I read some older replies and see you don't have the car now. You mentioned shrinkage though, how thin was the thin section? Was thinking us printing some things for around the grill/bumper area but if shrinkage occurs on thin parts I might have to think about which way to use the prints, whether as the part itself or just as the mold.
Shrinkage might have been the type of material, I hear that ASA is best for outdoors applications, whereas I think I used a nylon based material. Thin sections were probably only 2mm thick or so
may i know what material you use ?
This was Nylon X from Matterhackers
How did you take that measurement to model 3d part which perfectly fits at intended
Friend has a 3D scanner... I was lucky! :)
Did you print the parts in PLA, PETG, or ABS?
It was NylonX from Matterhackers
What 3D printer do you use?
What type of printer do you have? Thanks!
Hi Pedro, mine is a bit of a custom job as it was an old printer called a "Rigidbot Big" and I eventually modified it to the point now where I'd consider it "custom"
What filament did you use?
Matterhackers nylon x
What printer do you have?
It's a Rigitbot BIG from a 2014 kickstarter... I modified it a lot with a Titan Aero hot end and new controller etc.
What plastic filament did you use ? Pla?
In this case it was Matterhackers Nylon X but for most of my projects it is simple PLA, yes :)
...what material did you use for printing? Maybe I missed it in video...
Matterhackers Nylon X
Could you use pla for this part?
Likely would get soft in the hot sun or melt beside the exhaust...
where do i download 3d files of car parts?
How did you measure the diffuser to make the model?
I have a friend with a 3D scanner fortunately. Otherwise something like this would be near impossible to measure by hand or without tons of trial and error.
@@EmbraceMaking An alternative way of tackling those measurements would be a contour gauge. It wouldn't be perfect but it would make the task of translating curves to CAD extremely easy, specially if the gauge has a ruler stamped to you can reference to it!
Can you please share the stl file
Is it possible to 3d print a Ram Air box for a 96 firebird
Just like the original? They are very hard to find and expensive as hell.
Anything is possible! For really big parts you may want to print the parts, graft them together and make a mold for fiberglass or carbon fiber. Really big pieces will have more of a chance to split and warp if they are made of more than 2 parts in my opinion.
Have to look into it . Thanks.
Im gonna print a spoiler fot my aixam and wrap it in carbon fiber
I have creality cr10 max so I will probably be able to print it in 3 pieces
Would love to see how it turns out! Do you have instagram or something ?
Embrace Racing I don’t and now I can’t make it by myself because in my country if you want to put something on your car you need a safety certificate :(
@@Legomaster-bj5ts Wow, what country are you in?
Embrace Racing I’m from Slovenia I’m 14 so I can drive cars that has 4hp so I bought this a ligier I wanted to modify it but if you install a spoiler or something like that you have to show them safety certificate that the company gave you...
super good durability. serves no purpose, neither visually nor functionally
How to make 3d print???????
In general? Or this specific part?
The "print seam" isn't a reality of 3d printing, you're just using the wrong settings.
The glazing putty you used is pretty terrible, it's affected by solvents, it becomes unstable, gets soft, and swells as soon as you hit it with more putty or paint/primer you should use a 2 part polyurethane based glazing putty.
Hi Josh, which slicer do you recommend and what settings for dealing with the print seam? Can you expand on that? Also, with the glazing putty, I have yet to have any issues and its been months still. I can look into the 2 part glazing putty though, where do you get yours from? Thanks!
@@EmbraceMaking I use cura , at the moment I don't remember the setting, there are multiple ways of doing it depending on the part you're printing. If you're not using supports or infill, a spyralized path meant for vases workes really well. But the seam you have from the start and stop on the exterior is preventable even with supports and in infill.
If you have a well stocked napa, they will typically have a 2 part glazing putty but I do believe I've seen it at AutoZone and Wal-Mart at times. I like to buy from actual automotive paint stores whenever possible.
cool, but ricer
I thought it was pretty tame, not all that tacky but everyone has their opinion :)
@@EmbraceMaking i said it was cool as well ;-)
