The curve network is first bend using a curve as profile. Then it is thickened using Dendro. A last tool is used to flatten the bottom in order to have a stable bowl, I added some plastic pads in order to not scratch wood (sand is quite abrasive).
I followed design guide provided by SandHelden, mainly minimum thickness must be 5 mm, it is also best to have a smooth shape.
I took the cheapest sand (black) and ordered a white color. As they have no food certification if I want to use this bowl I certainly must add some an edible varnish.
For your design, you can have a price very easily on SandHelden Website
Cool, how much is a print in that size? And how does the rough surface of the bowl fare against softer fruits (apples, peaches, bananas, etc.)? Isn’t it too abrasive?
I agree that the sand is quite abrasive, so I think a varnish is the solution and also a necessity. By the way SandHelden is doing sink and various object with seems to be soft (varnished).
This one is design by Stephan Bassing.
I can say I am quite impressed by the result as the steps are quite softened, only visible on flat horizontal places.
I made it to be a bowl but my main goal is to have some portfolio with various objects and techniques. At the moment I have a Cardboard fruit bowl, 2 low tables in aluminium 3 objects in sand (vase, fruit bowl and lamp).
Seriously 300 $ dollars for plastic shoes. Seriously 1 million for a car … If your purpose is to comment on the madness of our world you better live on a cave and keep your non constructive comment to yourself or go on facebook or other social media.
The price here is indicative of a technology and a size of an object. I prefer to make prototype of useful stuff than art object.
I don’t like your tone so for the future, if you can stay away from my post I will be pleased.
250€ for a nice quality, state-of-the-art fruit bowl isn’t too expensive. What’s 250€ nowadays? It’s like 3 tanks of gas here. The fruit bowl is potentially something that can last for generations.
that sounds like sls print, those are expensive printers, that justifies the price you paid i would say, though i dont have any experience commissioning prints but i recently bumped into one of these and got interested, you basically can not afford one for home use or small projects only, those are serious tools.
I have done others design with this shape. I put that on sinks with same sizes as what SandHelden is doing, but they are not interested. I like the first.
Yeah, the first one is beautiful! I like number 4 too.
So do they 3d print the sand model and then glaze it or so they use the 3d print to make a mould?
I’m thinking this would be nice to CNC from wood… maybe just make a wooden lily pad. The problem is that all the beautiful texture is on the bottom of the lily pad! It could look nice if it were made from wood with a glass bowl on the inside so you can see the venation.
They 3d print them and apply a coating, no mould. From what I understand the first use of 3d printing sand was to make single use mould for casting metals.
And yes using the pattern with wood would be nice.
Do you think it is as tough as ceramic? Your fruit bowl looks quite fragile but perhaps the glue is like a resin that gives the object strength and durability?
Good question, I am not sure my design for a a fruit bowl is good for the purpose. But it seems solid enough for many others uses that have no shocks or that are quite thick. Lamp, vase, sink, art …
I don’t think so. On their website, they don’t really go in-depth on material properties.
Generally, binder jetting results in parts with inferior mechanical strength, compared to a process like powder bed fusion.
However, there’s also only marginal shrinkage and wrapping, which makes it a viable technique for producing bigger parts and I believe it can produce many colors.
