How to Solvent Smooth FDM Parts

5 0 Expert
The normal surface finish of FDM parts is suitable for most purposes, but in applications where a smoother surface is required, solvent smoothing is an alternative to sanding, filling, and mass finishing. Solvent smoothing utilizes a chemical agent to smooth a part’s surfaces (Figure 1). This process modifies the surface of FDM parts by eliminating layer lines while preserving feature detail and part accuracy. The smoothing agent can be applied either as a liquid or a vapor and it is quick and nearly labor-free. The finish achieved can mimic that of injection molded parts.

What You Need to Know When 3D Printing with Thermoplastics

2 0 Expert
Today, a majority of consumer products and production parts are made from thermoplastics. Thermoplastics are typically used in manufacturing techniques like injection molding, compression molding and machining, but with the invention of 3D printing, they became available for additive extrusion and sintering processes. A new door to advanced manufacturing has opened with 3D printing materials similar to the conventional thermoplastics familiar to engineers and designers. Thermoplastics are plastic materials, or polymers, that become pliable when heated to a specific temperature and solidify upon cooling. Types of thermoplastics include acrylic, ABS, Nylon, PLA, polycarbonate (PC), polyethylene and other specialty, high performance materials. If your part requires strength, rigidity or high temperature tolerance, then thermoplastics are a great option to fabricate your production component or prototype. Using 3D printing, engineers can make parts with the most commonly used thermoplastics, such as ABS, polycarbonate, a variety of blends, as well as thermoplastics engineered for aerospace, medical, automotive and other specialty applications. There are two additive technologies at Stratasys Direct Manufacturing that utilize thermoplastics: Laser Sintering (LS) and FDM (Fused Deposition Modeling).

How to Orient Parts for Strenth, Speed or Surface Finish

2 0 Intermediate
Build optimization is dependent on a part’s function (conceptual model, functional prototype, manufacturing tool or end-use part). Based on the part’s function, the user must select the appropriate orientation to balance or optimize surface finish, strength, or build time of the part. By following these best practices, you can cut down on time and waste.

How to go From 3D Scanning to 3D Printing

2 0 Intermediate
A 3D scanner is a device that analyzes and captures the geometry and colors of physical objects to transform them into digital 3D models. The scanning process collects sample points from the object’s surface and generates its geometric shape through extrapolation. There are many different 3D scanning technologies and each one comes with its own advantages, limitations and cost. Stratasys tested two types of Creaform 3D scanners: the HandyScan 700 and the Go!SCAN 20. These portable 3D scanners can be used for a wide range of applications, offering a simple and intuitive scanning experience, providing fast and reliable results. The Go!Scan 20 scanner can capture 3D data in color. It provides a very fast measurement rate and requires minimal data post-processing. The HandySCAN 700 is used mainly for taking measurements and reverse engineering. This scanner is fast at delivering accurate and high resolution 3D scans while remaining simple to use. All phases of product design, from concept through manufacturing, can benefit from the workflow combination of 3D scanning and printing. This process can reduce the number of design iterations and the time between each, lowering the total cost of each prototype. The following is brought to you by Stratasys:

FEA Results in Color 3D Printing

1 0 Intermediate
Finite element analysis (FEA) is a computer-based method of analyzing and simulating the behavior of components under a variety of conditions, including force, temperature, vibration, and motion. FEA calculates displacements, strains, and stresses under internal and external loads. These predictions confirm if a design is suitable or if modifications are required to prevent failure. This tutorial comes courtesy of Stratasys.

3D Printing: Tip Selection FDM Best Practices

0 0 Intermediate
To minimize build time and ensure feature details are built, it is important to select the correct tip size for each part. Using too small a tip on a part can significantly increase build times. Example: a part with a 5” z-axis dimension will have 500 layers using a T16 tip, 715 layers using a T12 tip, and 1000 layers using a T10 tip. The following tutorial is brought to you by Stratasys.

How to Paint FDM Parts

0 0 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 Apply Custom Toolpaths for Thin Walls and Bosses

0 0 Intermediate
When processing an STL file, smaller or larger toolpath widths are sometimes required to achieve proper fill for certain portions or features of a part. While changing the tip or modifying global toolpath settings for the entire part will generally work, oftentimes it is unnecessary. Custom Groups provide a means to specify different toolpath parameters for an individual curve or curves. The following tutorial is brought to you by Stratasys:
