Instructions for Objet Alaris 30 3D Printer

The Alaris has a high print resolution (.001 in) using an acrylic-based material that gives a nice surface finish that can be sanded and painted to look like a finished part. To print a part using the 3D printer, follow the job submission instructions.

The downside to the acrylic-based material is that it is more brittle than the ABS-based 3D printing materials used in the Dimension uPrint printer, and may not be appropriate for parts that need to bend or withstand impact loads.

Industry Resources

Cost to print is $.45 per gram of material (model + support)

Lead time:
Printing will be done on a first-come first-serve basis
Expect a lead time of at least 3 days. This may vary depending on availability and if issues arise

Part Limitations
Must fit within the net build size: 11.57 in x 7.72 in x 5.9 in (width, length, height)

Price and Time Estimations
Material costs are incurred not only from the part volume, but also from the support material. A general volume estimation including the volume of concave cavities should give you an approximate estimate.

Estimated time in minutes = (160 min/pass/in) x N x h + 8 x N + 10

  • N = 1 for parts that are < 2 in wide
  • N = 2 for parts that are > 2 in wide
  • h = height of part
Note: parts can be oriented in a number of ways on the printer bed. When measuring the part for a time estimate, be sure to approximate an orientation that optimizes the time.

Examples of parts
Notice the effect of price and time on the complexity of the part. Although the part itself may not be large, cavities, thin features, or complex cuts require support material which significantly adds to the time and cost.
