The Objet Eden 333 enables cost-effective three-dimensional rapid prototyping and manufacturing using UV light-curing resins deposited in super fine layers (as thin as 16 microns) by a print head. Complex, accurate, high resolution solid parts and moveable assemblies grow on the build platform in just a matter of hours!
Fab Lab Tulsa’s 3D printer services are available to lab members only. If you haven’t already signed up to be a lab member, take a moment to sign up online or drop by the lab in person Tuesday through Saturday. Corporate memberships are also available.
Fab Lab Tulsa chages $40.00 per print hour to create 3D parts on the Eden 333. (effective 3/12)
Lab staff operate the Eden 333 on behalf of lab members.
TO PRINT A PART contact the lab at 918.779.6025 or email info@fablabtulsa.com and supply our staff with a 3D part file. Included in our printer charge our staff will consult each member on their part, provide a cost estimate prior to starting the job, perform all of the printing, and contact each member when the part is completed.
See our Design Tips below to guide your part’s design.

Software
Objet Studio Software suggests the build orientation based on part size or required build speed, then automatically processes the STL files and generates necessary support structures in real time. The software creates a precise path for eight jetting heads to simultaneously deposit UV resin for model building, and a second, gellike UV resin material for any necessary support structures.

Design tips
Geometry:
The minimum recommended wall thickness 1mm and minimum detail size is 0.2mm. However, objects need enough strength to be self-supporting. For example, large, bulky geometries connected with thin structures (like a character with a big head on a skinny neck) could break in handling and should be designed to avoid this. If you have features that extend and converge to a point (eg a cone) they should be at an angle greater than 10 degrees.
Nested objects (objects floating within another object), hinged objects, and interlinking objects like chains need a gap of 0.5mm between objects.
Support Material:
A jelly-like support material is printed alongside the plastic and is washed away using a high pressure water spray in post production. Your model needs to have enough strength to survive this process. If you have very intricate geometry that the water spray cannot get into, then the support material may not be able to be cleaned off.
Hollow objects require a drainage hole to remove the support material. For example, a hollow cube needs a small opening somewhere in it so that the support material can drain out after printing.
Finish:
The surfaces of parts are smooth and have a matte finish where the support material encases the geometry. However, where the support material doesn’t need to touch the part, ie the top surface of the part, the finish will be glossy.
