Sealing FDM Models

EmailFacebookLinkedInTwitterShare

The Fused Deposition Modeling (FDM) 3D printing process of layering extruded material makes FDM parts porous. This can be a benefit for some applications such as Thermoforming that requires air to be drawn through a tool. However, sealing a part to hold an airtight vacuum may be necessary for other applications. In 2016 I wrote a blog, FDM Build Parameters to Create a Vacuum, using software parameters to create a denser filled part. This method requires using advanced Insight software […]

What is Local Fabriacate for Desktop Metal?

EmailFacebookLinkedInTwitterShare

As cloud-based software, FabricateTM maintains a secure connection to Desktop Metal servers at AWS. However, we understand that some customer environments face security restrictions that require all computation and data to be kept on-premises. For this reason, we have developed a local version of Fabricate. A local Fabricate installation allows you to use many of the same features found in the cloud-based Fabricate software, including job setup and management,  without requiring a connection to the cloud. Local Fabricate lets you manage […]

Tray Arrangement in GrabCAD Print

EmailFacebookLinkedInTwitterShare

In GrabCAD Print, the Arrange tool has two options for automatic arrangement: “Arrange tray” and “Arrange project.” They work in the same way, except that Arrange tray will only arrange parts on the current tray, and Arrange project will arrange all parts across all of the trays. Here’s how they work: Each part has a theoretical bounding box (cube shape) drawn around its largest dimensions. The parts are then placed on the tray(s) starting in the home corner (varies by […]

How do you print different durometers with image wrapped parts (OBJs and VRMLs)?

EmailFacebookLinkedInTwitterShare

Using Stratasys’ newest rubber-like material (Agilus White) is necessary to change the durometer. Its use in VRMLs and OBJs is limited right now, but it is possible. There isn’t a button or bar in GrabCAD Print that allows you to adjust it. You must load Agilus White instead of Vero White in your color palette. When you do this, it will print the soft Agilus White where it would normally print the rigid Vero White. You adjust the durometer by changing […]

Replacing your Objet Desktop Waste Container

EmailFacebookLinkedInTwitterShare

Printer waste contains partially cured polymeric material, collected during normal operation and maintenance of the printer. For safety and environmental reasons, this material is kept in a special leak-proof, disposable container. The container has a capacity of 1.8 kilograms of waste material—usually enough for several weeks of printer use. The printer application displays a warning message when there are 1.5 kilograms of material in the container and stops the printing when the net weight reaches 1.8 kilograms. Above 1.5 kilograms, […]

Dimension 1200 Loss of Extrusion and Tip Replacement

EmailFacebookLinkedInTwitterShare

There are times when your printer may experience a loss of extrusion condition. The print head may be moving with no material coming out of one or both of the tips. To diagnose and recover from a loss of extrusion condition go into Maintenance Mode. Press Maintenance-Machine-Head The head will move to the center of the chamber. The display will read Model Drive Motor Stopped. Press Forward and the drive motor should start turning. It may take up to 30 seconds […]

Sacrificial Tooling 101 – Part 1

EmailFacebookLinkedInTwitterShare

It’s known that a simple material inversion in Insight can give you some pretty unique and powerful results in your print. This is definitely the key to a few of the more advanced applications we can achieve on FDM. The purpose of material inversion is fairly simple. Essentially, you’re simply flipping the model and support material toolpaths on your piece so that model prints where support would be and vice versa. The power of this, inherently, is now you have […]

Desktop Metal: X/Y Calibration

EmailFacebookLinkedInTwitterShare

The X/Y Calibration on a Desktop Metal 3D Printer is intended to calibrate the offset between the metal and interface extruders. The process consists of printing a series of metal lines and then printing interface atop those metal lines. The user then visually inspects the location of the interface lines and enters the found values to the user interface screen on the printer. Notes: X/Y Calibration is required upon the first print X/Y Calibration may also be run if you […]

3D Printing Jigs and Fixtures

EmailFacebookLinkedInTwitterShare

When you need to put complex assemblies together that have a lot of different pieces it can be a challenge to do it efficiently, let alone easily. What makes a job like this much better is creating a custom fixture to hold of your parts in place while you do the assembly. This allows you to put the parts together much safer, quicker, and more efficiently, which is what matters when working on a high capacity assembly line or even […]

Using the CMB file format with GrabCAD Print – Part 2

EmailFacebookLinkedInTwitterShare

Part 2 of 2 – Importing a CMB File Stratasys FDM (Fused Deposition Modeling) technology utilizes a CMB (Coordinate Machine Binary) file format as the code to drive its equipment. CMB files are typically created with the advanced Insight software for F370 and Fortus level machines, but GrabCAD Print can also export and import a CMB file. In Part 1 we discussed how, when and why to export a CMB file from GrabCAD Print. In this blog, we will focus […]
