I now enjoy mandarin juice - thanks to you! However i'd warn people, pla + citrus acids = probably not very good, so wash right after using!

MattS, Check the license. It is OK to sell this with proper attribution.

It looks like your design is being ripped off and is up for sale.


Looks like you could also Juice your wife with this... :P #HadToBeSaid

Depends on the plastic you use - there are a few available.

What software do you use to create this juicer?

Im the 1000th collection lol

Printed this tonight without support, did the hollow version and man this thing is SOLID! I love it!!! thanks for the stl!

Failed twice for me on a MakerBot Replicator2 at different stages. Was using PLA

Is this safe? I hear a lot about how because of the pores in 3d printing making things that come in contact with food will make a bacteria breeding ground. Any thoughts?

Read below.. PLA = Safe. ABS = not

I didn't print it yet but you could print it with Raptor PLA. It's dishwasher safe and very resistant.

If you read my post it didn't have to do with the type of plastic it is made of. All 3d prints (including sintering) have very small pores that bacteria can easily inhabit. They will breed and make things unsafe contaminating them. This is why you are not supposed to make any cups or foodware no matter what plastic(yes even food safe plastic). You have to coat the plastic in a glaze coating. So I was asking if this was safe for tat reason. I don't know if the acids in a lemon may neutralize any threat or if the author never heard of this problem before.

Would an acetone smoothing step followed by some outgassing perhaps fix the pore issue? Seems like it would, and it would make the result quite pretty. Acetone evaporates quickly, leaving just the smooth, shiny plastic.

Yea I think I have read somewhere that they may help, The only problem that I would foresee is not actually getting all of the surface smooth or if the acetone bath just makes it seem smooth but If you put it under a microscope you would still find a pores structure. I am not sure if this is the case just something to keep in mind, best bet would just be to glaze anything food wise like what they do with ceramics.

Even with an acetone bath (which only works on ABS, not PLA), you still have issues of lead poising and other contaminants coming from the printhead. Printheads are not sterile and you have in your prints everything from you previous prints (so if you used ABS, ever, it will be in the prints). Home prints really are not meant for food safe objects. People look to plastic way to much as being safe/inert material, when it really isn't.

What makes you think that ABS is not safe and PLA is ?

Actually, none of the plastics used in 3D-printing can be food-safe as long as the FDM process IS NOT a food-safe process. Meaning that even food-safe filament (which have received an FDA certification), are no more food-safe, once printed !
Since commercially avaible 3D-printers are relatively new, we don't have enough perspective to assess those kind of contaminations.

However, one solution is to apply a food-safe coating to your printed parts if you are afraid of the unknown ! I do not have any suggestion on which brand, but I guess some silicone coating spray could be easily found over the internet.

Can anyone help me? I need this in any other format, for example SOLIDWORKS. I need tu cut it because I print it and I don't remember that I have my PRUSA i3 with software limitation of 100 mm height. I don't want to re-print it again, I only want it in any format that I can work with.
Or anybody that can send me it the part over 100 mm.

Why not just use another slicer Eg Cura ? i use it with my prusa i3 if you need support just send me a message

Could it possibly be published with a longer handle?

Making this right now in clear blue! Thinking it will be perfect key lime size.

A really beautiful object that's caused more comment than anything else in my kitchen. I've made it my Thing of the Week on http://3dgeni.ushttp://3dgeni.us so do take a look and leave a comment!

That's awesome, thanks! It's cool to see one at full size, I haven't tried that myself. Looks like a great site.

Thanks, Walter. As I said, a great piece of design - the internal struts are much more elegant than a simple fill would be, even though you can's see them. And the good thing about the full size design is that it works for small lemons too!

Which model printer did you use for this? Looks great!

Thanks! I used an Afinia H-Series 3D Printer (same as the Up! Plus)

Great design and a blast to print! Thanks for this one...

Thanks! I'm glad you like it!

How long did it take to print?

I think the prints in the pictures took around 1-2 hours each, but they're significantly smaller than the original dimensions.

Yes. Awesome. Do you know if this is safe with all common printer plastics?

Many people have talked about nothing being food safe if made in an FDM machine. The reason is that not only is ABS made for the machines not food safe, but that also there are parts of the machine that are not food safe that comes in contact with the melted plastic.

So even if the PLA itself is food safe, it will be contaminated with non food safe materials in the process of making it. It probably wouldn't effect you very quickly, but it could take years off your life. I don't think it's worth the risk.

The brass alloy generally used in the hot-end contains lead (3% by mass I think). Though lead is a toxic heavy metal, I think the amount of lead being mixed in with the plastic is neglectable. I've printed drinkware in PLA. Whether you want to take the risk is up to you, but I think that there are far more harmful things and substances that you expose your body to on a daily basis. It has to be said that not all printers use brass and therefore no lead.

Hopefully someone who knows more about this will answer, but I believe ABS is not food safe. Some PLA plastics claim to be food safe, but I don't know if they all are.

Short answer. PLA is food safe, ABS isn't

The biggest problem is that at a cellular level these things have a lot of bumbs where bacteria can grow.

You can sand 3D printed items down as well as you like. If you use finer grades of sandpaper and finish with lapping paper, you can get a finish smooth enough that bacteria can't hide in the plastic, unless it's scratched. I'd sand down any food item I printed.

As far as the material not being food safe, a lot of people seem to state that without much verification, so I talked to a testing laboratory. I was thinking of sending a sample of ABS off that's been through a printer. The guy I talked told me how much plastic is contaminated with lead. It's actually pretty scary. Most uncertified plastics are heavily contaminated. One plastic he tested came back as 3% lead. That's not a tiny amount.

Until I've sent them a sample of plastic to test for lead, I'd apply a food safe clear coat to any 3D printed item that would come into contact with food and drink, or recast it in a food safe material.

Does this print without support?

Looks absolutely possible without support.

yeah it should be printable without support, the overhangs are about 50 degrees off horizontal at the worst spots. On my printer the quality degrades a bit on the overhangs, but it's only noticeable if you look closely.
