• Build Materials - Vero Family (rigid), and Agilus30 (flexible, rubber-like), offering over 360,000 colors from opaque to transparent characteristics and shore value variations of flexible to rigid MSDS
  
• Digital Materials - Over 360,000 colors including translucent color tints
  
• Supported File Formats - .stl, SLDPRT, SLDASM, .wrl (vrml2)
  
• Finish - matte or glossy (gloss surface only applies to geometry not in contact with support material)
  
• Support - soluble SUP 706 support removed by staff
  

* Print modes from 30-microns (0.001") to 16-microns (0.0006") with accuracy typically falling within 0.1 to 0.3 (0.004" to 0.01")

Schedule a 3D Print Service appointment for job order drop-off by contacting us by email or phone, and specify available dates with time frames per date.

At your appointment, please have your model file(s) on a thumbdrive as either .stl or .wrl (vrml2).

During your appointment you will work one-on-one with an LGS staff member to verify your model file(s) for printing, and determine the material assignments. If file corrections are required, those details will be reviewed with you so that you can make the necessary adjustments to your files. An additional appointment may be required for job order drop-off.

Once your model file(s) are verified for printing with material assignments chosen for your geometry, you will be given a quote for printing charges and your job order will be submitted into our production queue.  You will receive notice by e-mail when your parts are printed and through the necessary post-processing steps for cleaning.  Payment is required in full at the time of job order pick-up. Please see details for payment terms.

Because the J850 can print in multiple materials, with each material family offering different properties, a part printed with multiple material assignments is called an assembly. In order for the J850 to successfully print assembly model files, separate “watertight” shells must be specified in the file’s geometry.

Geometry features requiring fit testing, including closures, hinges, threading and seating for fitted parts, should be prototyped first by printing smaller test sections that contain the critical areas or features specifically.  This way, smaller parts can be tested for functionality and fit ahead of the larger and more expensive final print runs.

$$ Money saver!

Geometry requiring verification of color, transparency treatments or transition of materials (such as flexible to rigid), should be prototyped or tested by printing smaller “chip” sections of the larger model. This will help target the final details and ensure success of the final printed work.

$$ Money saver!

Drainage holes will be necessary for the removal of support material and successful post-processing of printed parts. Hole sizing and positioning should be planned for at the beginning of the design process. Complicated geometry parts with difficult to reach areas for cleaning, such as internal undercuts or thinner curved sections, will require special attention to the positioning of the drainage holes.

Parts utilizing clear or translucent materials may need to be polished or painted to achieve full transparent material properties.

3D printing charges for the J850 are determined by the gram weight of model resin used, plus the support material required to complete the build. The price examples provided are an average cost per family of model resin type. Job costs will vary due to the specific model resin type used, build conditions, model geometry, volume of support material needed for bed run, and amount of Digital Materials printed (composite or percentage mix of model resin types). Price quotes are issued at the time of consultation appointment. Price examples provided are for solid models with required support.
