FAQ for Stratasys J750 3D Printer

Q 1: Can there be issues with the print heads with the Polyjet systems?A 1: As all precision equipment, the 3D printer needs the proper care and attention. If the system is treated according to instructions, problems rarely occur. For example, we (D2M Solutions), have a Connex machine in our facility, which has never required a print head replacement. However in order to cover any eventuality, the J750 comes with a 3 year warranty on all parts and 8 additional print heads per year.

Q 2: How easy is it to transfer colour from my design onto a printable file?

A 2: This is made possible with the J750’s new software, Polyjet Studio, where you can import vrml files and print your model with full colour capabilities.

Q 3: How suitable is this system for creating accurate surgical planning models?

A 3:  This system is ideally suited for this particular application, because it can print parts in multi-colour / multi materials giving surgeons the most accurate representation of CT data available today. The ability to print clear parts further enhances the usefulness of the models.

Q 4. I understand that it is possible to print in flexible material that is black but is it possible to print flexible material that is transparent as well?

A 4. Yes, TangoPlus is a material with flexible properties that can be combined with a color to create your own tints and opacities.

Q 5. Can I print mixed trays?

A 5. With the J750 you have the ability to print mixed trays, for example print a part that is flexible and black and another part that is rigid and transparent in the same build job.

Q 6. I have heard that Polyjet technology is office friendly, what do you mean by this?

A 6. Polyjet printed parts do not require any messy post-processing or specialized facilities. Also, as the resins come in sealed cartridges, there is no chance an operator will get exposed to them as opposed to other vat-based technologies where liquid resins are exposed to the environment and operator.

Q 7. How can we know how much a part will cost us before we print?

A 7. The J750 comes with a pre-processing software that will very accurately calculate the time needed to print the part, as well as the quantity of resin that will be used.

Q 8 : Please explain the dental applications on the new printer :

A 8. There is a dedicated dental line of Stratasys printers that use the materials necessary for the dental industry, including some materials which can be cast using specialized casting processes.

Q 9 . How can I prepare a file for full colour 3D printing?

A 9. You can use adobe, save the file in VRML and import the VRML into Polyjet Studio to print a model with full colour capabilities.VRML – Virtual Reality Modeling Language – a text file format where, e.g., vertices and edges for a 3D polygon can be specified along with the surface color, UV mapped textures, shininess, transparency, etc.

Q 10. I want to print Architectural 3D models. Will you provide 3D printing services? Using J750 How much would cost me per cm3?

A 10. Currently we do not have a J750 locally, but we are part of a global manufacturing network and can offer services. In order to better assist you please send us your 3D model in STL or VRML to bespoke@paradigm3d.com & print3d@paradigm3d.com.

Q 11. J750 has one size or there are smaller machine sizes? To print a colored skull, do I have to pick each different color or the software will do that for me?

A 11. The J750 comes in one size and the maximum build size is 490 × 390 × 200 mm (19.3 x 15.35 x 7.9 in.) Anything can be printed within this build envelope and the Polyjet Studio software can deal with vrml files to automatically colour the 3D model.

Q 12. Can we print 3D Models of Piping and Civil Structures designed in Smart Plant 3D and PDS

A 12. We can print piping but if the diameter is too small, it’s very difficult to remove the support structure as we have to do it manually. Pipes need to be open from both ends. Anything in STL/Obj can be printed.

Q 13.  Is the polyjet studio really easy to learn and handle even by amateur staff and if the objs are imported in the software with all their properties. Is it possible to change the model after import?

A 13. You don’t have to be an engineer or designer to use the polyjet studio software.
You can only change the model in the 3D design software but not in the Polyjet Studio.

Q 14. How economical will it be to take up printing products on a large scale? Is it more beneficial than the traditional method of mass production employed by industries?

A 14. 3D printing can better deal with complex or customized parts whereby mass production would be impossible in most cases and not cost-effective. Also 3D printing is ideal for low-volume production. If very large quantities of the product are required, then it may be more suitable to go for mass production/traditional manufacturing, but this places restraints and a compromise on the final product, not encountered by 3D printed. Each case could be assessed to determine the preferred production method.

Q 15. How does this printer understand where or what materials to use now?

A 15. We have to pick and choose the parts and assign materials to it in our s/w Polyjet studio.

Q 16. There is a high interest now to be able to use recycled plastic. Can this be used?

A 16. Nope. Not at the present time. Materials come in sealed cartridges.

Q 17. Can you import a design from software like Blender or Maya to Polyjet Studio ?

A 17. Any s/w which can export water tight 3D files to STL can be used.
