Fused Deposition Modelling 

(FDM) Printing

Fused Deposition Modeling (FDM) 3D printing offers immense value by producing robust, functional parts with remarkable dimensional stability and accuracy. Arguably the best choice for a wide variety of applications ranging from delicate and intricate models, to rugged and heavy duty composite components.  FDM technology provides engineers and designers with rapid and efficient production capabilities. Whether for prototyping or end-use applications, FDM empowers the creation of high-quality, functional parts, meeting the needs of various industries.

What is Fused Deposition Modelling (FDM)?

Fused Deposition Modeling (FDM) 3D printing provides an extensive selection of advanced thermoplastics that are on par with those used in traditional manufacturing processes. This makes it an excellent choice for producing end-use parts, conducting real-world material property tests, or creating durable jigs, fixtures, and templates for production purposes. With 14 distinct 3D printed materials available, Forge Labs’ FDM (Fused Deposition Modeling) technology offers remarkable versatility, making it well-suited for a range of specialized applications. These applications include medical devices, electric static dissipative parts, or high-temperature scenarios where Flame, Smoke Toxicity (FST) ratings are of utmost importance.

When you require robust, functional parts that exhibit dimensional stability and can tolerate visible layer lines, FDM 3D printing services are the way to go. Forge Labs utilizes Stratasys Fortus series machines renowned for their exceptional accuracy, part repeatability, and one of the largest commercially available printing envelopes in the market. With these machines, you can manufacture large and intricate designs using a wide range of thermoplastics, all in a single build. The maximum build volume of 36 x 24 x 36 inches ensures that even complex projects can be accommodated. The strength and precision delivered by Stratasys FDM machines set them apart as the preferred choice for achieving remarkable results.


ABS is a cost effective, durable and versatile material with good impact and chemical resistance. It is widely used in prototyping and functional parts.

ABS (acrylonitrile butadiene styrene) is great for functional parts and prototypes. ABS matches approximately 80% of the properties of injection-molded products but is rigid and inflexible. Due to the FDM printing process, design freedom is limited and layer lines are visible. ABS allows for a wide variety of color and use cases.

Impact Resistant



Widely used for durable and functional parts; it combines strength, chemical resistance, and low cost.

PETG is plastic that possesses strength and durability similar to that of ABS. The material is both chemical and wear-resistant so it can also be used in outdoor and food-related settings. PETG is made with one of the most common synthetic materials – polyethylene terephthalate (PET), which is modified with glycol. As a result, PETG is much tougher, stiffer, clearer, and easier to use in 3D printing than PET.
