Safety
Safety
The J850 is very safe and locks the door whenever it may be moving or heating so there are very few safety rules.
The tool to scrape material off the bed is very sharp! Always orient the tool away from yourself to avoid injury.
The equipment provided to aid support removal have certain risks involved with using them. Please reference the support removal guide for more information on safety of those pieces of equipment.
The safety data sheets for all of the Stratasys materials used in the lab can be found here
Rules
Rules
Because the material is so expensive, prints on the J850 must be approved by staff.
You may remove your own prints from the printer, but please allow staff to remove other prints
Please notify staff when you want different materials in the printer, it wastes a lot of material to change one of the resin cartridges so we will not be doing it often.
HOW DO I GET ACCESS TO THIS PRINTERS
HOW DO I GET ACCESS TO THIS PRINTERS
The J850 is a higher end printer with more intricacies and more expensive material than the Ultimakers and therefore requires training. You must first have printed several times with the Ultimakers before moving to the Stratasys J850 printer. To complete the training, prepare a print file according to the First Print guide with any part you want (we encourage smaller parts) and then demonstrate to a staff member your sliced file and proper procedures for starting and finishing a print.
MATERIAL COSTS
MATERIAL COSTS
Because of the high cost of using the Stratasys J850, its material is subsidized by 50%.
Please calculate your price here by plugging in the amounts of each material used into the corresponding cells.
You are permitted one free print under $10.00 every two weeks
Always refer to the Material Store page for the most updated pricing.
When you select Print in the GrabCAD print slicer, you can see how much of each material you are using. If you are not on a computer in the lab, you can select Estimate to get these numbers. Then plug them into the calculator to calculate the price.
How does it work?
How does it work?
The Stratasys J850 employs what it calls PolyJet technology to create multi-material, full color 3D prints. This technology functions very similar to a paper inkjet printer, using CMYK photopolymer resins to create different colors and flexibilities which it then cures with UV light building the part layer by layer. This type of additive manufacturing breaks many of the barriers of other 3D printing methods because it can create highly detailed parts (of up to 14 micron layer height) and allows for many different colors and physical textures to be made in one part. Some of the drawbacks of this printer are that the material is very expensive, at around $7/in^3, this printer should not be used for low fidelity prototypes. Additionally, because it is always dropping an ink-like resin onto each layer, it has no ability to do any overhangs, therefore support must always be used and it can be difficult to clean out and get a nice surface finish.

Materials & Applications
Materials & Applications
The Polyjet printer is great for delivering aesthetic results with full-color capability including texture mapping and color gradients. This lets you create prototypes that look and feel like real products, and accurately show design intent in color, material and finish. The prints are extremely expensive so please be sure the print can't be achieved on any other printer.
