Nice design.

This image brings up a point I've been pursuing for years: If we look at the image, it is very obvious that it's "fake". It is too perfect.

What would make it more realistic? Some imperfections, of course, but how do we do that in CAD? This is a problem that's easy to state, but hard to solve. Any comments?

Re: pic: Cheesecake, anyone?

You can use photo realistic decals, but that would only work for certain lighting conditions and angles.

I good size bite taken out would be far more realistic, I think.

Re: pic: Cheesecake, anyone?

Depending on the software you can also apply textures, but again it will only work so well. There are a few ways you could pattern "defects" into the part as well in the way of modeled bulges and gouges. It really depends on what you are going for. You usually can adjust the sheen that parts have as well. I know Inventor and Solidworks have different plastics with different shine to them. A major problem with a cheesecake is the fact that you almost always have browning in certain spots, and that would be the most difficult part to model in my mind.

Re: pic: Cheesecake, anyone?

Using CAD software to make photorealistic pie is like trying to eat soup with a fork. It might work if you really try, but it's the wrong tool. The spoon is either a photo-editing program or a 3D animation program. Either one allows you to generate random noise patters to texture the pie and to create random surface variations (in 3D) to account for the imperfections. Not only that, you would have much more control over the lighting and shadows.

Re: pic: Cheesecake, anyone?

The slice is 1.42in tall, has a 2.35in radius, and a 50 degree angle.

The crust is 0.14in thick.

Not sure about the weight. I couldn't find "cheesecake" under the materials list.

Re: pic: Cheesecake, anyone?

Maybe we should have a CD-wide CAD challenge to see who can make the most realistic looking slice of cheesecake.

Details.

Compare and contrast. The crust has a crumbly, pitted texture. I wouldn't call that an imperfection, in the same way you wouldn't expect the surface of a gravel to be flat.

Also see the profile and color gradient of the top - the raised ring around the edge is darker (because of how thin it is?).

Finally the junction where the crust meets cake isn't uniform at all, looks like there is a bit of mixing/penetration.

Re: pic: Cheesecake, anyone?

Sadly, no. We couldn't get anyone to agree to this. Our current plan is to print it using an industrial triple injection 3D printer, but instead of feeding it ABS filament, we're going to use cheesecake, whipped cream, and whatever the crust is made of. As you can see, we have left plenty of room in the design for expansion... (i.e. cherries)

Re: pic: Cheesecake, anyone?

Can I ask what extruder/printer you are using? Would be very helpful for other teams that are attempting to do this. I was planning to find a way to 3d print a Hawaiian Pizza, but a cheesecake would do. Also, are there any rules on 3d printed cheesecakes, or are you just using this as an offseason project?

11-08-2015 16:30

Re: pic: Cheesecake, anyone?

I believe it's the same one that McDonald's uses to print their food. We will be using the latest model. With regards to rules on 3D printed cheesecakes, I believe all 3D printed parts are allowed, but I know that a lot of people get yelled at by the green shirts at competition every year for bringing food into the pits .

11-08-2015 16:38

Re: pic: Cheesecake, anyone?

Interesting that you are choosing an additive method. Historically, I believe standard cheesecakes were turned on a lathe. Modern technology can use an injection molding process.

Re: pic: Cheesecake, anyone?

We have always just ordered cheesecakes from online then cut them with the band saw. Set up a jig to cut it properly it and you can easily get it down to perfect slices.

Re: pic: Cheesecake, anyone?

So does the manufacture and working of cheesecake on the small scale really make sense?

I mean your competition has The Cheesecake Factory and that might make it hard to compete on costs and scale.

Why wouldn't you do COTS?

11-08-2015 20:21

Re: pic: Cheesecake, anyone?

We've procured locally, then cut them using a lightweight hand saw with a very small kerf, which can be procured from culinary supply shops as a "cake knife".

[pernickety rant]And it's a PIE! Cake doesn't have crust and a filling! Boston Cream Pie is really a cake, but cheesecake is a PIE![/pernickety rant]

And, OBTW, the biggest flaw I found in the original rendering (ahead of lack of texture) was that the cheesecake filling was translucent rather than opaque.

11-08-2015 22:14

Re: pic: Cheesecake, anyone?

Crust is typically just graham cracker crumbs and melted butter to hold it together. A good cheesecake just doesn't need cherries, or whipped cream for that matter though. I have a habit of making cheesecakes when I get bored, so I would be highly interested in purchasing one of these cheesecake 3D printers.

Re: pic: Cheesecake, anyone?

Darn that is a really good rendering of a cheesecake.

In all seriousness, there is no technical issue preventing you from printing a cheesecake, or a pizza for that matter - but you'd still need to bake the pizza.

McD's uses high-speed large-capacity printers, but they've found real wheat buns are more cost-effective.

As for the filament cartridges, Cheddar isn't the right material for this kind of cake.

What's scary about this thread is that it can turn into a real, serious discussion at any moment. And there are people here with the chops to actually do it. I mean, they already print chocolate and cupcake icing...

Re: pic: Cheesecake, anyone?

Well 3D printers can be enclosed.
Easy Bake ovens are enclosed.

I did once suggest using an incandescent light bulb as a 3D printer enclosure heater.
Turn up the wattage - or better yet - use an infrared lamp and lower it to the pizza to produce localized heating (runs to the pizza patent office).

Re: pic: Cheesecake, anyone?

What would be better though, this method or finding a way to heat the bed to a high enough temperature to cook the pizza? I have no experience cooking pizzas so I don't know how they are generally cooked, but wouldn't heating the bed make it so that it wouldn't have to be enclosed? Also I have no idea if a 3d printer's bed can get to a high enough temperature to cook a pizza.

Re: pic: Cheesecake, anyone?

Who designs a slice of cheesecake to be 7.2 pieces per whole? No one will settle for the 0.2 piece. That's just crazy talk.

Re: pic: Cheesecake, anyone?

Heated beds from printed circuit boards might survive this. It would probably take several heater cartridges to get the heating even. Then again there is good old nichrome or Inconel wire.

Re: pic: Cheesecake, anyone?

Uhhh... the cake is cone-shaped and there are 350 degrees around the center. I cut it into seven pieces because 7 is a nice number... also America.

13-08-2015 20:04

DonRotolo

Re: pic: Cheesecake, anyone?

You need to get out more. Or at least observe more closely. Surely there is a non-chain type Pizzeria near you? Go visit and ask questions (as if you were in the pits at a regional...) Living in northern NJ would help (pizza capitol of the world, arguably).

Pizza ovens are generally at 450 to 500 degrees. They universally have stone 'floors' to maintain the temperature evenly and avoid the cooling effect of an uncooked pizza. So yes, one CAN make a bed that will cook a pizza, but you really want to print it first, then cook it.

15-08-2015 00:05

Henrique Schmit

Re: pic: Cheesecake, anyone?

ABS printers alraedy have heated beds, so you could base your bed on something like that, they go up to ~110ºC

Has anyone figured out how to print the irregularities in the cake to make it more accurate and useful? Maybe adding bubbles inside the filament would create a pattern like that

Re: pic: Cheesecake, anyone?

Ummm... Are we talking per capita? Because here in Becker, MN we have 4 different joints in a town of 4500; or one pizzeria per 1125 residents. And if you include the local bars and c-store, it jumps to 7; or one per 643 residents. Only one is a national chain. We love Pizza and robots here in Becker!

Maybe this style of printer would work for pizza/cheesecake. But, would this be considered a pizza printer?

15-08-2015 17:28

GeeTwo

Re: pic: Cheesecake, anyone?

Yes, yes. An automated pizza baker would definitely have to have separate construction and baking chambers; unless you print the bubbles in, the crust has to have time to rise at a lower temperature, and go quickly to a much higher one. (I suppose you could move the pre-heated stone to the pizza, but that sounds even more problematic.) I also seriously doubt that current 3-D technology can passably reproduce a hand-tossed and pressed crust, or even a machine-kneaded and rolled one.
