Objet Eden 260V

Objet Eden 260V in the Maker Space

The Eden 260V developed by Stratasys is a rapid prototyping 3D printer. With a choice of 18 materials, the Objet Eden260V prints ultrafine 16 micron layers for exceptional detail, complex geometries and very thin walls. PolyJet 3D Printers jet layers of liquid photopolymer onto a build tray and cure them with UV light. The layers build up one at a time to create a 3D model or prototype. Fully-cured models can be handled and used immediately without additional post-curing. Along with the selected model material, the 3D printer also jets a gel-like support material specially designed to uphold overhangs and complicated geometries. It is easily removed using a WaterJet. PolyJet 3D Printing technology has many advantages for rapid prototyping, including professional quality and speed, high precision, and a wide variety of materials.

Good STL in Netfabb

After you have designed the 3D model of your desired part, export the part in the STereoLithography (.stl) file format. The STL format describes only the surface geometry of the object instead of the object as a whole. Then open the file in the Autodesk Netfabb software to repair the file.

We will only process STLs which have:
1 shell per continuous part
0 border edges
0 invalid orientations
0 holes.

Even if Netfabb reports no invalid orientations, if we see red triangles in repair mode there is a problem with your model. Print at your own risk.

Fixing a File

Main Article : Fixing STLs

Students are welcome to use any of our computers for fixing their files in Netfabb or Rhino.

Here are some tips to get you started at home:
Ideally in Rhino you want one closed polysurface before meshing.
NetFabb is better at meshing than Rhino. Consider opening the 3dm file in NetFabb to generate the STL instead.
Default repair is decent at fixing holes, border edges, and invalid orientations. Then try using boolean join to reduce shells down to 1.
If boolean join results in multiple shells then most likely the shells are not contiguous. Consider deleting extra shells in model.
Extended repair wraps an existing STL in a new mesh. This can severely alter geometry and result in thin walled sections.

Printing a Part

Once a file has been processed and is ready to be printed, find a shop supervisor to help add it to the queue. The length of the queue is highly variable, and the time it takes to print a model may range from a few days to being ready by the end of the day it is submitted. Keep in mind that the Objet queue can be very full during finals, midterms, and the time surrounding IPRO Day. An estimate of queue length and a time to come pick up the part will be communicated to you once your part is added to the queue. Once a part is successfully in the queue, it is ready to be printed. The average part takes about 1 inch per 30 minutes to print, while a very complex part could take full days to print.

Cleaning Parts

Main Article : Cleaning a Part : Form2

Once the model has been successfully created, it is removed from the printer and separated from the printing tray base. From here, the model is cleaned using a power washer to get the jelly like material off of the part. The support can come off using toothpicks, scrapers or gloved hands if necessary. Once this process is complete, the part is ready to be picked up by the creator.
