Stratasys 3D Printing: F123 Series Camera Shroud Print and Install

F123 Series Camera Shroud Print and Install   If you have a F123 series machine and use the camera to view your builds through Grabcad Print software or the mobile app, you will notice in rooms with a fair amount of ambient light that there is a reflection. This stems from the double pane window and the camera being between them.   Stratasys has released a customer level fix for this issue and below are how you go about doing it. First thing you will want to do is make sure you have software version 1.3.5360.0 or newer installed in your printer. You can check this on the machine itself

Stratasys 3D Printing: Waterjet Cleaning System Has No Lights, Wiper, or Pump Working

Issues with Waterjet Cleaning System   If your waterjet suddenly stops working where the lights do not come on, the wiper arm doesn’t move, and the pump itself doesn’t come on when the pedal is pushed, it may be an easy fix. All of the power for this unit goes though the electrical box on the rear of the WaterJet and then distributed from there. The main thing we find that causes the system to go down is a simple fuse.   So if you power your WaterJet up and it doesn’t have lights on, this is one of the first thing we want to check. First, being that the

Stratasys 3D Printing: 3rd Party Software to Verify and Repair STL’s

3rd Party Software to Verify and Repair STL’s   Occasionally you may come across a part that comes out of your 3D printer looking horrible in quality. There are particular things within these defects that can help tip you off as to what is wrong and if it is your machine or your file that heeds help.   If you end up with a part that has shards of material jetting out of it or through the support, generally triangle in shape, it is a problem with your STL file. Holes, open areas, or even gaps in parts can become filled with 3D printing model material that was never designed

Stratasys 3D Printers: Print Head Alignment for PolyJet Desktop Printers

Print Head Alignment for PolyJet Desktop Printers   You may find your parts have some rough edges over time or after replacing or swapping your print head locations on your Objet printer. This can be due to the heads being out of alignment and need to be adjusted. Doing the adjustment is fairly automated and easy to do. You will need your clear transparency sheets, scotch tape (optional), and a magnifier or loupe to look at the print to do this.   With your Stratasys Embedded Printer Software open on the desktop and the printer lid closed, go to Options > Wizards > Head Alignment to start the procedure.

Stratasys 3D Printing: Data Shifting and Reseating Head Cards on PolyJet Printer

Data Shifting and Reseating Head Cards on PolyJet Printer   From time to time, on your Objet Desktop PolyJet printer, you may see your print offset print in the X or Y direction. This happens when the information coming from Objet Studio was not processed correctly internally, or the machine itself has confused itself and loses its reference. There is a possibility there is an issue internal to the machine with boards or cables, but this is a way to help determine where the problem is.   The first thing we would try to fix this is to shut your printer down, unplug it from the wall, then reseat the

X, Y, & Z Calibration for your Uprint, 1200, and Fortus 250mc Printers

On your FDM system you can run a number of different materials and/or colors through it. Over time the tips deteriorate and need replacing. Some colors such as blue and orange tend to leave trails of the material in the tip as well that can come out even after purging and will be embedded into your other color parts. For instances like this we recommend keeping spare tips for these colors so they don’t ruin a part after you do a material change. One of the most important things to do after a tip change is to make sure your brush flicker is not worn, the tip shields are good,

Polyjet and FDM Material Expiration Date and Shelf Life

Both Polyjet and FDM materials have a shelf life to them and Polyjet has a hard expiration date which it won’t read in the machine past that date. The shelf life for the material is from when it’s manufactured till when it’s no longer available. For FDM machines the shelf of the material is about 3 years from manufactured date as long as the sealed bag and cartridge is not opened. If the bag is opened the shelf life goes down to about 6 months. Material being open to the environment absorbs moisture and will cause print quality issues and shorten tip life expectancy. The manufacturing date can be found
