3-d Sculpture Modeling Programs - Sculptris

Am looking to use Sculptris for presentation of ideas to clients of abstract sculptures – see attached jpeg of sample sculpture to see what I am trying to do.

Am interested to make sure that when I carve a stone block that the design generated in Sculptris will closely approximate the size of the block. Want to make sure before I start promising a sculpture to a client from a design in Sculptris that it is doable in the real world. In addition, want to make sure that the design is actually carveable (can get my hands into all the tricky places to chisel & sand).

To make sure it is doable in the real world how do I put a template/ruler over the work area that approximates what the size of design I am dealing with is? For example, my next block to work on is a 24” x 24” x 36” tall block of stone to carve. The aspect ratio of the stone could be seen as 1:1:1.5. Or is there a ruler I could use that is set on the x, y, & z axis (analogous to Adobe Illustrator or Photoshop) to make sure that the fantastic design I come up with will fit within the parameters of the existing stone. Would hate to blithely start carving a design on a block of stone to find out it does not work & ruin a 2,000 lb block of stone. That would be about a $4,000 oops – like to avoid those kind of mistakes.

Would like to get input to see if Sculptris would be the best software to use before investing a lot of time in a marginal venture. Sculptris has the right price, but will it work or can I get plug-ins to make it work?

Appreciate your input.

Re: 3-d Sculpture Modeling Programs - Sculptris

Sculptris is a free application that was purchased by Pixologic to act as a feeder program, hoping that people would get started with its simple interface, want more features, and then upgrade to Z-brush, which has them, along with a button that exports your Sculptris model into Z-brush. So I don't think you're going to get a whole lot more features or plug-ins added to that product.

I believe Z-brush has the sort of rulers you're looking for; here's a video that shows how to set them up: http://vimeo.com/58145135 Z-brush 4R6 (the current version) lists for $795 and works on Windows or Macs. (We can do a little better on the price). Using free software is a good place to start, but it might be worth spending a little if it will help you avoid expensive mistakes.

Agree completely Andrew. Late last night dropped Sculptris because of it's irritating limitations & am now working on a 30 day trial of 3-d Coat. They seem to be geared more to how my brain works. Time will tell.

Re: 3-d Sculpture Modeling Programs - Sculptris

Hi, Andrew. My first time back on the forum since 2010. How have you been?

I just (re)installed Sculptris today, oddly enough, thinking I'd give it a try again. I have rekindled my interest in doing 3D-printed sculpture, now that the build envelopes have enlarged and the costs have shrunk a bit. imaterialise looks like a good site for getting prints made relatively cheaply. Their prices are lower than Shapeways, anyway. I also read that, as of 2010, their maximum build dimension has reached up to 6 feet, as well. Good enough to finally accommodate the dimensions considered to be "small sculpture" and to finally avoid being stuck with something jewelry-sized.

Re: 3-d Sculpture Modeling Programs - Sculptris

Hi All
I have joined the ranks of the 3 D world.
Spent a few hundred hours learning ZBrush and love it.

Now what I am doing is creating works in the usual way (Analog) and adding an interior structure using ZBrush to design it and then I will print the mold and sand cast just the interior in bronze and weld the two together.
A mix of analog and digital!

I am very excited about it and this is the first piece.

I created the original piece in 2013 and did not like the stand that held it up.
The Frame was not strong enough and I was afraid it would break in shipping.
As well I did not really like the frame, aesthetically it did not work for me.

With Zbrush I created a new support system that I am about to print.
here are the photos of the bronze as it is and the design of the supporting structure.

Having great fun…

Let me know what you think.
Don't worry lots of thick skin on me!


The first three pictures are the piece as it is now
Photo 4 is a bad scan of the original piece with the interior structure inside
The last photo is only the interior design.
I'll post the finished work when it is done in Jan. 2016

Cheers Blake

Re: 3-d Sculpture Modeling Programs - Sculptris

That piece is an interesting blend of the organic and mechanical. Is the whole thing going to be in bronze, or is the outer skin going to be some kind of plastic? Is it going to stand up by itself, or will it need that suspension device? How far along is it at this point?

Re: 3-d Sculpture Modeling Programs - Sculptris

The piece is in bronze and the interior will be cast in bronze.
I will print the mold in sand.
The piece will stand on it own then.

Nice work. I remember loving Z Brush back in my motion design days. The software is nothing short of brilliant.

Blake when you wrote " print the mold " how exactly did you do this. Was this to scale? Thx.

There are all sorts of people printing molds, it is just the negative of the digital file, but it is much more difficult as the print is built of layers of sand (or other power material) and these layers are bound together with a type of binder (glue). The rub is that you must open the mold to get all the unbound sand out of the mold in order to pour the bronze in.

It is a one use mold. You can find lots of foundries that will do it for you.
All you need is a digital file... so you build one in a program like Zbrush

I am LOVING Zbrush it is amazing!!!!!!!!!!!!!!!

Once you have a digital file you can make it any size you want.
I am printing a test at 20 cm and once we have a great product then we will print the same file in 3 pieces at 60cm each so the sculpture will be 180cm or about 6 feet tall.... same file different size


What I am working on with my foundry in Bologna is a ceramic shell cast.
We are working on a print in a material that will burn out of the shell without leaving ash or residue so that the surface of the bronze is smooth and clean.

I'll let you know how it works out!!!
Blake

Re: 3-d Sculpture Modeling Programs - Sculptris

That sounds pretty cool; it sounds like you've jumped in with both feet. So in this case, you're actually printing the positive form, not the mold, right? In PLA? That's supposed to burn out pretty well. Have you tried casting in a printed sand mold yourself? That seems like a great way to cast things that would be difficult to make molds of.
