Umm... OMG!

Ho ho ho (that Shapeways-Claus laughing)

I uploaded a sword. What better thing than a metal sword ?

(yup, a 1 meter metal sword would be a killer, but let's stay reasonable... this one is 30 cm long...)

43$ in WFS... °° cheap eh?

From the special contest page:

The maximum dimensions of your model can be up to 50x50x50mm.

You model dimensions are 1.9 cmH x 5.9 cmW x 30.9 cmD. Your model is too large in two of three dimensions and therefore a non-valid entry. Think smaller, like a sword pendant.

Aaah well, I guess I've been overenthusiastic :-)

5cmx5cmx5cm is more appropriated for jewelry and small things indeed...

Uh another question, it's about the angle thing... I don't really get it to be honest.

What angle are we speaking of? Could you show some practical example of thing we can and things we can't do?

Sorry if I appear a bit slow but I think it might interest other people.
#3 aws357 on 2008-12-18 10:26 (Reply)
Aws, LOL. Good point: you did check out the page?

If you look at the picture here:

Does it make sense now? Or were you confused about this?
#4 Joris Peels on 2008-12-18 11:13 (Reply)
That's exactly the image I am confused about :-)

What does it represent and how does it relate to the nice designs in the contest page?
#4.1 aws357 on 2008-12-18 12:08 (Reply)

I'm sorry its confusing.

If you make a 3D design and want to get it printed out in Titanium:
Right angles and other steep angles will tend to look good. Low angles set at less than 35 degrees will tend to look uneven and not as attractive. If you make an overhanging angle as the "table" picture shows, the bottom of it will look ugly.

So if you want to make the prettiest possible design to win the Titanium contest you will have to take these things into account.

Mmmmh I guess I am starting get it... (will nag in the forum in case I don't anyway :-) )

"""As you've probably heard by now this contest will not be a walk in the park."""

It's a REAL challenge to pack those design rules into the 50 x50 x 50 box... Thanks shapeways for firing up my synapses so strongly once again!.. I look forward to seeing where everyone else goes with this
#6 Rob Mack on 2008-12-18 18:51 (Reply)
Yep, I'm really really curious too to see what you guys will come up with.
#6.1 Joris Peels on 2008-12-18 18:59 (Reply)
What is the strength of this stuff like? Would I be able to make tools out of it?
#7 Peter Zich on 2008-12-19 17:03 (Reply)
Hi Peter,

it is really strong!

"As far as we know you will be amongst the first people ever to be able to have your own personal design made and then 3D printed in titanium. There are some companies out there using the technology, but even their usage is rather limited and direct access to these machines? Unheard of!"

I do appreciate your enthusiasm. But some of your assertions are a bit overstated. DMLS has been on the scene for some time and there are a number of private companies who can offer this process to a knowledgeable designer/artist. I applaud your desire to raise the awareness of this process. You may want to include a bit more information about how this process works so your designers can maximize it's potential and approach their work in a iconoclastic manner. This could result in an out come that justifies the process, and not vice-versa.

What information do you think we should add to the contest page in order to improve the contest? If you have any insight or previous experience we'd love to hear from you!

#8.1 Joris Peels on 2008-12-19 23:27 (Reply)
What sort of clearance is needed for non-fused hinges?
#9 Peter Zich on 2008-12-19 20:48 (Reply)
oh no! ;-)
Are you really going to try hinges straight away?!

Will try and get you the info, but I assume if you are a few tenths of a mm apart it should be ok.

#9.1 Peter Weijmarshausen on 2008-12-19 20:54 (Reply)
Oh, no (don't worry). I'm just curious for possible future use. Although I may not get to because of the price :-(
#9.1.1 Peter Zich on 2008-12-19 23:30 (Reply)
Is the high price due to the use of a metal like titanium?

Would it be cheaper with magnesium (macbook hulls) or plain steel or aluminium?


What about gold :p ? (I can imagine the people out there getting paranoïd and vacuuming the place everyday to spare any speckle of gold dust...)


Even shorter : "Why titanium? Why no other metals (yet)?" :-D
#10 aws357 on 2008-12-22 10:04 (Reply)

The process we use: DMLS can work with several other materials(such as steel or bronze alloys). We opted for Titanium because we liked the results and the look of the finished products better in Titanium.

This contest is an initial exploration of 3D metal printing. If you guys are enthusiastic enough and want to order models made with 3D printing in metal we will see how we can offer this for you.

At that time, depending on what you guys want, we will decide which metals to offer.

Regarding the contest rules, would it break the rules to have a design that, when molded, fits the max dimensions/volumes but is designed to be unfolded or cut apart and reassembled into a shape that is larger than the max dimensions allowed during molding?
Thanks much.
#11 toraishikuru on 2008-12-23 17:45 (Reply)
Hi toraishikuru,

this would not break the rules. Actually sounds like a cool design.
Can't wait to see it.

kind regards,
#12 Peter Weijmarshausen on 2008-12-23 21:37 (Reply)
This is great for some people, I personally think i will try and get some rings, or ornamental items made if you start to offer this.
It would also be a great way to make special replicas or replacement parts for small machines that use metal gears, sprockets, screws, etc.
#13 Ethan Parker on 2008-12-23 22:13 (Reply)
How do we enter the competition? Is it simply we're entered if we upload a model & it's within dimension & volume limits?
#14 Greg Walker on 2008-12-26 10:42 (Reply)
"Enter the contest by uploading your own design to Shapeways with the tag: metal3dprint."
#14.1 Peter Zich on 2008-12-26 15:18 (Reply)
Hi Joris,

Do you have more details on the material which will compose the printed model? I was curious in particular about temperature ranges (need something more concrete than 'low' or 'high') but I thought in general people might be interested in this information when designing their entries. Thanks!

#15 eMansipater on 2009-01-02 19:58 (Reply)
I should also add I was curious as to whether walls would be watertight at .2mm (and if not, at what thickness would they be? )

#15.1 eMansipater on 2009-01-02 21:14 (Reply)
How can I participate with my model that's loaded in Shapeways?
#16 Garenc Philippe (Homepage) on 2009-01-05 21:29 (Reply)

Garenc please read:
This includes everything you need to know how to participate.

kind regards,

What resolution will be used, how fine will the layers be?
Cheers, Ann Marie
#17 Ann MArie Shillito (Homepage) on 2009-01-12 20:12 (Reply)
The resolution is 0.2mm, the layersize is the same.
#17.1 Arjan Moors on 2009-01-16 14:34 (Reply)
I sent in my entry yesterday evening, could you please update the contest page.
