PolyJet Materials and Uses: Tips and Tricks

12 4 Intermediate
Materials are critical to prototyping and production success. At the heart of any great application is the right material: one that performs as needed under the application’s conditions. This is just as true for 3D printing as it has always been for molding, machining, and casting. While the 3D printing industry has a wide variety of materials to choose from, ranging from plastic to metal and wax to paper, the selection is often quite limited for a given technology. It is even more restricted for specific 3D printers, with one exception.

How to Paint FDM Parts

5 1 Intermediate
There are many reasons for coating FDM parts. These include UV protection, sealing, shielding, or surface modification, but painting FDM parts for an aesthetically pleasing finish is the most common. Painting brings a product to life by adding depth, contrast and character. This is true for concept models, marketing samples, and finished goods. For product development and many production applications, paint completes the desired look and feel. With a little know-how and a touch of patience, models, prototypes, and parts can look like production parts. The following instructions are for creating top-quality painted parts. For applications that do not require this level of finishing, skip any unneeded steps. A good paint finish traditionally starts with sanding and filling.

How to Give Your 3D Printed FDM Part the Smoothness of Injection Molding

6 1 Intermediate
This tutorial will demonstrate how you can give your FDM printed part the finishing smoothness of injection molding. The Finishing Touch Smoothing Station can dramatically improve the surface finish of ABS parts that are built using FDM technology. The semi-automated smoothing process is compatible with FDM’s entire line of ABS plastics.

PolyJet Best Practices: How to Prototype Surfaces with Varied Friction Coefficients

0 0 Intermediate
Friction is defined as the force that opposes the relative motion or tendency of such motion of two surfaces in contact. The friction coefficient of a prototype’s surface is a functional component, not an aesthetic one, and simulates the end product’s mechanical properties. A well-designed prototype that takes friction into consideration can have the following advantages: an improved grip for the end-user, reduced part wear, simulated movement functionality and sliding abilities. PolyJetTM ConnexTM 3D Printing systems provide a solution for prototyping surfaces with varied friction coefficients that were impossible or cost-prohibitive to prototype in the past. By being able to print several materials in one build process, Connex systems can produce prototypes with varying friction areas on one given part. Users determine the friction coefficients for different areas of a part according to the load factor. This saves time and money by providing an easy solution for prototyping complex parts whose dynamic friction coefficients can be tested in a single build process.

How to Prepare a 3D Printed Composite Tool for Use

0 0 Intermediate
FDM composite tooling, similar to traditional tooling technologies, typically requires some level of post-processing depending on the size, application, and complexity of the tool. The most common post-processing operation for FDM composite tooling is sealing. The following is brought to you by Stratasys.

How the New KeyShot & GrabCAD Print Integration Makes Applying Labels to 3D Models Very Easy

2 0 Intermediate
Labels represent your product and brand. When designing your label, you want it just right especially after all the effort and time spent designing it. The last thing you want to worry about is color accuracy, position, readability, and all of that transferring perfectly when printing out your model. Thankfully, now that KeyShot integrates with GrabCAD Print, label headaches become a thing of the past with how simple this new workflow can be!

How To Properly Sterilize FDM Parts

4 0 Intermediate
Fused Deposition Modeling (FDM) is an additive manufacturing technology that is used in industry for development of three-dimensional models. Because of its ability to provide highly accurate models, FDM may offer many benefits to those wishing to use it for a range of medical applications. FDM can be used to build models that aid physicians in the surgical planning process or in the production of a surgical implant. It can be used to achieve a patient’s agreement prior to surgery by providing a preoperative simulation device. During surgery, an FDM model can act as an orienting aid or a template for resection. FDM can also be used to directly manufacture medical implants out of bioimplantable materials. However, such surgical devices and implants will come into direct contact with sterile body tissues and fluids, and therefore, must be manufactured out of sterilizable materials.

PolyJet Multi-Materials For Impact Resistance

0 0 Intermediate
Impact resistance, or toughness, is defined by the relative susceptibility of plastics to fracture under stresses applied at high speeds. In materials science and metallurgy, impact resistance is a material’s resistance to fracture when stressed. It is defined as the amount of energy per volume that a material can absorb before rupturing. Many of today’s appliances have to endure impact due to how they are used, accidents, safety requirements, and more. The impact resistance of plastics can be improved by adding a soft material coating on top of hard plastic materials. The following is brought to you by Stratasys.
