Stratasys F370

From Idea Shop Wiki
Stratasys F370



The Stratasys F370 developed by Stratasys, Ltd. is an FDM (Fused Deposition Modeling) 3D Printer. FDM printing is ideal for models that need to mimic the strength and detail of plastic injection molding. The Stratasys F370 prints by extruding layers of thermoplastic that stack up to form a 3D model of the desired part.

Parts will have different mechanical and tensile properties depending on the infill settings and how the part is oriented when printed. Unlike the Stratasys J55, prints can only be done in one solid color.

Processing

Main Article : Processing 3D Files
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:
If 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.

Safety

  • Only staff may operate the machine.*
  • When removing parts from the bath, be sure to wear safety glasses, gloves, and other appropriate PPE.*
  • Staff: Components are hot. Always wear safety gloves and long sleeves when working inside the machine.


Printing a Part

Main Article : Printing a Part

In order to print a part on the Stratasys F370, please fill out a remote file submission request. Submitting this request enters your part into the printing 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 3d print queues are 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.

It is the responsibility of the student to ensure that the file provided in the remote file submission is correct and ready for printing. After submitting the request, Idea Shop staff will respond to your request with a quote and other job details.

Machine Proficiency


In order for an individual to advance in machine proficiency they must demonstrate ability to perform certain actions or tasks. All levels include abilities and concepts from lower levels.

This section is primarily for Idea Shop student workers.

Level 0

Individual has demonstrated they are capable of:

  • Analyzing a student's file with a Netfab proficiency level of 3 to prepare for printing
  • Basic operating parameters of the Stratasys F370. (Reference per the User's Manual).
  • Identifying location of power switch
  • Overall familiarity with general 3D Printer system operations.
  • Installing spool into material carrier cartridges.
  • Toggling chamber lights.
  • Pausing a build.
  • Resuming a build that was paused.
  • Canceling a build.
  • Understand and properly store ABS.

Individual understands the concepts:

  • The Stratasys F370 Plus uses ABSplus colour materials.
  • Wall thickness requirement for Stratasys F370.
  • Color choices available with the Stratasys F370.
  • Be aware that 3D Printers can be very hot to the touch, especially after a recent print job.
  • ABS material is negatively affected by exposure to atmospheric conditions and high humidity. Care and proper storage is paramount to ensure material wastage is minimized and clogging of the Stratasys F370 is avoided.


Level 1

Individual has demonstrated they are capable of:

  • Correctly loading and sending file to Stratasys F370 queue.
  • Align and securely place part on GrabCAD software.
  • Correctly starting a print job.
  • Correctly installing EEProm to material cartridges.
  • Changing material and support cartridges in their respective bays.
  • Proper feeding of materials.
  • Proper GrabCAD utilization and part orientation.
  • Removing a printed part from inside the Stratasys F370.

Individual understands the concepts:

  • A remote desktop account is required to send the file to the printer.
  • When placing part on build plate, don't orient the bottom of the part to hang parallel with the plate. Rather, angle large flat surfaces to make the part less likely to peel off during printing.
