If you use acetone (which works great for ABS, but sadly not for most PLA brands) at 20°C already about 25% of the gas phase consist of it. Don’t try to do it all in one coat; many thin coats will produce a much cleaner final product than one thick coat. Overall as you can see above, you will have to decide whether a smooth part is worth the risk. You can see how nice and smooth the pieces can turn out. The left half of the boat on the left was smoothed with ethyl acetate, the other half with MEK (which mainly only left a white residue). For sandblasting I am using a mixture of silicon dioxide and aluminium oxide as a blasting abrasive with a grain size of 0.2 to 0.5 mm and a pressure of 8 bar (116 psi). Crop Circular Image in Paint 3D. Smooth Tool in Illustrator is one of the tools that are widely used by the user. It will turn the epoxy slightly white, but since a very thin layer will be applied later on it doesn't matter and can't really be seen. Make sure that your work area is clean, well ventilated and read the instructions on your spray can so that you know at what temperature ranges it works best. Here, here and here are three more instructables by other members that you might find helpful. for a couple of minutes and both parts will stick together. Like with spray painting the part, I stick it to a handle with blu tack. Effective and can be constructed at very low cost. Once cracks have been filled up, simply sandpaper the surface to ensure that the structural symmetry remains balanced. Mastering the use of one will definitely take some time, so keep airbrushing till you hit the artistic heights you desire. That’s why both the Eraser tool and the Soften Edges dialog box apply these properties together. All you have to do is carefully paint the epoxy in a thin layer onto the 3D print. The tools you’ll need are: The Process: Polishing your 3D model is done with the aid of a polishing compound and a buffing wheel. In situations where you have used decorative filament such as wood, metal or ceramic and you need the material to shine, adding some polish or coating is the way to go. To show you how the different methods work I decided to go with everybody's favourite torture test: 3DBenchy. I was taught that you should never sand through the primer, especially if it is applied to wood, but I found that with PLA it doesn't really matter (unless you don't want to use another primer coat afterwards). Adequate ventilation at the floor area must be ensured as well. Here are a few of my project that I smoothed after printing, should you be interested: I started by using primer, but it didn't properly fill the holes, so cracks started to form. Mine can not:) I have even tried to machine it on a wood lathe and it does not like to be machined. Another thing that has happened to me was that the glue I used reacted with the primer and small bubbles started to form. So i would still have to spend 28$ to chip another chip or spend the money for the rfid stickers or reset. The Process: Polishing your 3D model is done with the aid of a polishing compound and a buffing wheel. It compares the solubility of PLA in different chemicals and also gives information whether using a certain chemical would result in swelling. Use the supplied foam brush, soak up some resin and apply it to the 3D print. Fortunately, you can use this little trick to smooth out those jaggies fairly quickly. Now start filling bigger imperfections and holes. Use a scalpel to remove all small imperfections, like oozing. 1. In a second build of this project I used an air eraser to smooth the runes. Iva atac hed a sample below. In my experience Black Primer Formula P3 (e.g. Smoothing Out The Rough Edges Of 3D Printed Objects | Asian Scientist Magazine Since THF is such a great solvent, most gloves are useless and it will eat right through them. Especially if you mask areas you can use the masking tape to hold the 3D print as shown in the picture on the right. If you take a look at my ibles from the last years you can tell that 3D printing is one of my favourite things ever. Ok, that's completely different from what you said in your first post, where you said you need to smooth the edges.

If you try their filiment, i strictly use the clear green and clear blue. Hazardous substances like ethylenoxide can diffuse through latex gloves and you definitely don't want those on your skin! I love Army Painter Base Primer (e.g. It will eat right through latex or nitrile gloves, so those aren't sufficient. Wow! (I don’t do this as I … There are a few more on my instructables page, feel free to check them out. on Introduction. I've tried epoxy and got poor results when it pooled and solidified on the part.I had better results with one part automotive scratch filler. But since in 2017 it was classified as "carcinogen in laboratory animals" (source), I decided to use it less and look for alternatives. Do not evaporate or distill it (especially not in a closed system) unless you have tested it. Make sure to work in a well ventilated area and that there is nothing nearby that might cause a fire. May 4, 2013. As you can see in the image on the right, the epoxy formed a really weird, absolutely not smooth surface. Simply add a small amount of solvent to the cloth and wipe the part with it. I paid 220$ for my printer from them and it prints as good as my makerbot replicator at school:) done ALOT of test prints against eachother haha.I live in the USA as well. In the Rendering menu set, Texturing > 3D Paint Tool > . Keep alternating through sanding with 120 and spraying filler primer until things like the dome on top are filled in enough to make one smooth surface, rather than the clear layer lines on top. I like using foam brushes (e.g. You can see a visualisation of the vapour pressure in the first image. I usually use two to three layers before sanding the first time. To blur the border real quick, select everything on the angel layer, go to select>refine edge>contract or shrink selection. As you can see in the next step it works really well with ICE PLA filament, but for example with HATCHBOX PLA filament (used in the picture on the left). from amazon), since it comes in different colours, sprays nice and even and works really well with acrylic paints. So far I wasn't successful in vapour smoothing PLA with ethyl acetate, but I decided to share my findings here. I enjoyed working with it, but sadly it is really expensive in Germany. When 3D printing complex or large models, it is sometimes advisable to 3D print different complimentary components and assemble them once all the parts have been 3D printed. I never thought about using epoxy, until XTC 3D was started being sold. this one). Today, with the right 3D printer, there’s virtually no 3D object you can’t produce if you put your mind to it. Question My four favourite methods to smooth PLA 3D prints are shown in the table below. I just think a rag and my fingers won't get the results I want :P, Answer Surround the object as best you can. Also, as you can see if you have a lighter part, you shouldn't use the same mixture I do, since it stains the piece. Back in 2013 when I started trying to find a way to smooth PLA 3D prints there was not much information around. When you mention jagged edge around the circumference, have you rendered your 3D scene (3D> Render). Please bear in mind that different PLA filament brands might behave different, since you will never get filament that is pure PLA. The smooth tool is used for making the curvy and rough edges of the artworks and objects that are generally present in the vector-based program smooth and glossy.

I (like most people) print mainly in PLA and while ABS is quite easy to smooth, PLA is a bit more tricky. After a bit of try and error I found out that disposable lip brushes work really well (e.g. Watch this video for tips on using 3D view mode.

I haven't tried it yet but I'm told wood filler putty diluted with acetone works very well and doesn't have toxic fumes. To soften and smooth edges with the Eraser, follow these steps: 1. This can easily be fixed with thixotropy powder (read more about it here). As EvilChemist points out in the comments in contact with light and air, explosive peroxides might form. Wish i could add an image but my phone doesnt want me to:)Thanks. It works perfectly though if you have a part with deep indents as the one shown in the third picture. In that year I won my first 3D printer with my Nerf Sentry Gun instructable. (For those interested in funny collage styles, the basic functionality of Paint is at your service.) Works great. here) is also very good. Because they are small, I'll need a small way to apply the chemical, do you think something like the Eyeliner Brush or Lip Brush from this kit would work? Simply leave it in water for about 15 minutes to get it soaked and go over the part with it. Another thing you have to be aware off when working with THF is storage. The correct ratio depends on the epoxy you use, so make sure to read the instructions. Make sure to use thin layers. You will have to get the right type of sanding paper (e.g. My shop temperature was at about 15°C during testing and even leaving the print for hours in the vapour didn't have an effect. Hold down the Ctrl key (Microsoft Windows) or the Optionkey (macOS) as you click the edges you want to hide. In other words, by softening the edges you have not smoothed the underlying CAD model, you have only altered the way the model appears on your screen.
