Foundry Patternmaking With FDM Technology

sandcasting-2

Danko Arlington is a sand casting pattern shop and foundry in Baltimore, Maryland. Danko bought a Fortus 900mc 3D Production System from Stratasys three years ago to assist in constructing new patterns for their foundry. Since then, Danko’s understanding of Fused Deposition Modeling (FDM) Technol[Read more...]

Design With FDM Technology in Mind

All design requires consideration of the manufacturing method, even for digital manufacturing. Some key considerations when Fused Deposition Modeling (FDM) Technology is your method of choice are: Conserving support material Ensuring feature strength Reducing build time This is easy if yo … [Read more...]

FDM Technology’s Ease of Use in Numbers

After listening to a webinar from a local provider of additive manufacturing equipment, I realized how lucky I am to be running Fused Deposition Modeling (FDM) systems from an operation standpoint. The presenter said he needed three system operators to run four additive manufacturing systems. (I won … [Read more...]

FDM Technology Meets MRI Makers’ Material Standards

To date, we've seen a dramatic shift in how the magnetic resonance imaging (MRI) industry is designing, developing, and manufacturing systems. A growing number of MRI coil design companies as well as MRI OEMs are using Fused Deposition Modeling (FDM) technology. FDM is the only additive manufacturin … [Read more...]

For Sand Casting, FDM Does More Than Just Patterns

The sand casting industry is looking to become more efficient, and Fused Deposition Modeling (FDM) technology has proven valuable. The first foundry/pattern shop to use FDM for matchplate patterns (about 6 years ago) has owned an FDM machine for 3 years now. In that time, it’s resorted to building a … [Read more...]

My Secret to Spotless Large FDM Parts on the 900mc

The Fortus 900mc is capable of producing extremely large parts, which requires a lot of material to be extruded. During these extended builds, the Teflon shield attached to the tip can become worn. Since tips are a consumable item and can be replaced between jobs, this wear isn't normally an issue. … [Read more...]

How I Conquered Color Change on the Fortus FDM Machine

Using colors on the Fortus systems is a great way to make your parts stand out, especially when creating an assembly or specialty parts for manufacturing applications. (Designated colors could signify safety, caution, no-fly, danger, etc.) However, one thing I've noticed is that after using a colo … [Read more...]

Metal parts from 3D prototypes

A customer asked me last week if the FDM technology can produce patterns strong enough to withstand the investment casting process.  Yes, parts built using FDM technology (fused deposition modeling) can produce high-accuracy complex patterns to make metal components. We have detailed applicatio … [Read more...]

Glass Filled Nylon vs. ULTEM 9085

A customer was considering a switch from a traditional manufacturing process to direct digital manufacturing, and he asked, "What material matches the properties of a glass-filled nylon (GFN) and can be used with the Stratasys FDM (Fused Deposition Modeling) process?" None of the materials available … [Read more...]

Using Insight Software to Create Custom Filters

With Stratasys Insight Software there are so many features available to make your part build exactly how you want it on a Fortus system.  The following steps show you how to build custom groups to change part porosity. Being able to easily create complex porosity with Insight software makes Fortu[Read more...]
