3D Printing Materials: A Comprehensive Material Selection Guide

1. ESSENTIALS (Prototyping & Visuals)

Best for: Display models, school projects, and concept validation. 


PLA: The standard for eco-friendly, detailed, and affordable prints, making it a popular choice in the material selection guide for various applications, including SLA printing. (Lead: 2 Days) 

HIPS: Lightweight and impact-resistant, HIPS is great for soluble supports or dissolvable molds, often used alongside DMLS printing and SLS printing techniques. (Lead: 3 Days)

2. FUNCTIONAL & OUTDOOR

Best for: Mechanical parts, brackets, and outdoor casings. When considering material selection, PETG offers the perfect balance of strength and ductility, with food-safe options available and a lead time of just 2 days. For outdoor applications, ASA serves as the UV-resistant cousin of ABS, making it the #1 choice for outdoor car parts and housings, with a lead time of 5 days. Meanwhile, ABS remains a traditional rigid plastic ideal for injection-mold prototyping and can be post-processed to achieve a smooth finish, typically with a lead time of 3 days. Whether you’re exploring DMLS printing, SLA printing, or SLS printing, understanding your material options is crucial for optimal results.

3. INDUSTRIAL & ENGINEERING

Best for: End-use manufacturing, gears, and high-stress environments. 


PC (Polycarbonate): Extremely tough and heat resistant, making it an excellent choice for bullet-proof reliability in DMLS printing applications. (Lead: 4 Days) 

PA (Nylon): Known for its high fatigue resistance, this material is ideal for gears, hinges, and snap-fits, especially when using SLA printing techniques. (Lead: 5 Days) 

PACF (Nylon + Carbon Fiber): This lightweight yet stiff material is the ultimate choice for robotics and drones, particularly suited for SLS printing. (Lead: 4 Days) 

PP (Polypropylene): With its chemical resistance and flexibility, this material is perfect for bottles, packaging, and living hinges, making it a versatile option in your material selection guide. (Lead: 4 Days)

4. SPECIALTY

TPU: Flexible with rubber-like elasticity, ideal for gaskets, phone cases, and seals. When considering material selection, TPU is a great option for applications that may also benefit from DMLS printing, SLA printing, or SLS printing techniques. (Lead: 1.5 Days)

ADVANCED MANUFACTURING

💧 SLA (Resin Printing)

High-fidelity detail achieved through DMLS printing results in a smooth surface finish ideal for jewelry masters, dental models, and miniatures. The quality resembles that of SLA printing or SLS printing, looking as if it came straight out of the injection molding machine.

⚙️ SLS (Selective Laser Sintering)

Batch Production: Strong Nylon powder prints using DMLS printing techniques, eliminating the need for support structures. This method is ideal for complex geometries and low-volume manufacturing runs, as outlined in our material selection guide for various printing methods including SLA printing and SLS printing.

🏗️ DMLS (Metal 3D Printing)

Use Case: Aerospace brackets, medical implants, and heavy-duty tooling can benefit from advanced manufacturing methods like DMLS printing. Materials include Stainless Steel, Aluminum, and Titanium, which are highlighted in our material selection guide. The benefit of using these materials is the production of solid metal parts with high thermal and mechanical strength, ideal for applications in aerospace and medical fields. (Lead: 7-10 Days) Additionally, techniques such as SLA printing and SLS printing can also be considered for specific project needs.
