We Offer a Variety of 3D Printing Materials
We offer a variety of 3D printing materials covering polymers, engineering plastics, composites and metal materials, supporting SLA, SLS, MJF, FDM, and SLM( metal 3D printing processes).
Select from rigid, flexible, high‑temperature resistant, flame‑retardant and biocompatible grades for functional prototypes, jigs & fixtures, low‑volume batch production and custom‑made end‑use components.
Our engineering team will assist you on material selection according to working conditions, mechanical property requirements, surface finish and cost target, helping you avoid common DFM mistakes in additive manufacturing and get parts that fit your real‑world application.
Why does material selection matter so much for custom parts?
Choosing the right material for custom parts is critical because it directly impacts performance, cost, manufacturability, and longevity.

Provide Various Materials of Additive manufacturing One-Stop Services for Different Industries
We provide engineering-grade metal and plastic materials for 3D printing services. Our engineers will work closely with you to understand your specific application requirements and recommend a tailored material solution that offers optimal strength, high precision, and exceptional cost-effectiveness.
3D Printing Plastic Materials: Resin, ABS, Nylon/PA, PA+Glassfibre, PLA, PETG, PC. Metal: Aluminum, Stainless Steel, Tool Steel, Titanium.

Resin
Extremely high precision, with relatively high hardness and rigidity, but usually lacks sufficient toughness. If your needs are for high-precision, aesthetically refined models, such as figurines, jewelry wax patterns, or dental models, resin is an excellent choice

ABS
One of the most widely used plastics in industrial production. Its toughness, impact resistance, and heat resistance are all superior to PLA and PETG. It offers high strength, high toughness, impact resistance, and good heat resistance, but is prone to warping and cracking.

Nylon/PA
Nylon possesses excellent impact resistance and wear resistance, along with self-lubricating properties, making it highly suitable for printing parts that require relative motion and bear repeated loads, such as gears, bearings, and snaps

PLA
PLA has poor heat resistance, low strength, and is brittle, but it gives a smooth finish and costs little. It's great for quick, low-cost appearance prototypes or educational models. But don't use it for any functional or load-bearing parts.

PC
High strength, high heat resistance, and excellent impact resistance — when you're pursuing ultimate strength and heat tolerance, PC is the material to choose. If your part needs to withstand significant force or elevated temperatures, PC is the way to go.

PETG
Good toughness, clear transparency, and low shrinkage. However, the surface wears easily and it strings a lot, so you need to tweak the settings. It's like an upgraded PLA, easier to print, stronger, tougher, and less warping.

Aluminum
It is specifically designed for applications demanding high dynamic load capacity and lightweight construction. It is particularly well-suited for manufacturing parts that require complex internal cooling channels, such as heat sinks and aerospace engine components, reducing weight while maintaining structural strength

Stainless Steel
It maintains high strength and rigidity while offering excellent corrosion resistance. This makes it the top choice across a wide range of industries, from food processing equipment and chemical facilities to surgical instruments

Tool Steel
Tool steel is engineered specifically for demanding industrial applications. It offers better thermal conductivity and can achieve extremely high hardness (HRC 54) after heat treatment. Its primary battlefield is the manufacturing of injection molds and metal casting tools, and it is particularly well-suited for producing complex mold cores with conformal cooling channels.

Titanium
Titanium alloys are often regarded as the 'pinnacle' material in metal 3D printing. They combine an exceptional strength-to-weight ratio, excellent corrosion resistance, and good biocompatibility. They are used to manufacture engine fan blades and critical airframe structural components, as well as customized artificial joints and bone implants

FAQs About Our 3D Printing Services
Why 3D printing?
The core reasons for using 3D printing to make prototypes can be summed up in three words: fast, economical, and free. It has fundamentally transformed the traditional model of prototype making, which was often time-consuming and costly, by enabling designers to quickly test, fail, and iterate. Moreover, 3D printing can produce irregular shapes that are impossible to achieve with traditional methods.
What 3D printing services do you provide?
Our mainstream printing technologies include SLA resin printing, FDM thermal molding, SLS powder sintering, SLM metal 3D printing, and MJF high-precision printing. We provide prototype printing and small batch production.
Request equipment list, contact our team: engineer@rpdmfg.com.
What if I am unsure which additive manufacturing process fits my chosen material?
Some materials work for multiple printing technologies, while others are process‑specific. Our team will match material‑process pairs to avoid poor part quality, and optimize your design following DFM for additive manufacturing.
What kind of quality assurance or warranty do you offer on orders?
One of the reasons engineers purchase from RPD is that we take on all the risks for you. We guarantee you’ll love what you get. Not happy with it? We’ll either redo it or give you a full refund. Your purchase is completely risk-free.
What types of 3D printing materials do you supply?
We offer a variety of 3D printing materials, covering engineering polymers, composite materials and metal materials.
- Polymers: Standard & high‑performance resin, PA12, PA6, TPU, PP, ABS
- Composites: Carbon‑fiber‑filled & glass‑fiber‑filled polymer powders
- Metals: Stainless steel, aluminum alloy, titanium alloy
What Factors will Influence 3D printing price?
1. Part geometry – shapes and complex designs, thin-walled, fine details and complex geometries require 3D printed parts with special supports, which will incur additional costs.
2. Material Selection – Metal 3D printing is much more than plastic. Besides, especial functional material and premium imported 3D printing is more expensive than domestic made material.
3. Tolerances & Precision – High-precision parts (automotive, medical) require tighter mold tolerances — which complicates design and increases cost.
4. The Size of prototype parts- the bigger and heavy parts need to use more materials, it will cost much than small size parts.
5. Extra surface treatment, like hand polish, painting, Electroplating, ect will up cost.
How do I pick the right 3D printing material for my project?
Our engineering team wull help you select materials based on your working temperature, mechanical load, chemical exposure, surface finish requirement and budget.
What is your typical lead time for 3D printing orders?
For ordinary resin and plastic 3D printing prototypes, the delivery time is 2–3 working days. For complex structural parts, carbon fiber materials, and metal 3D printing components, the lead time is 3–5 working days. For small batch mass printing orders, we provide flexible delivery schedules according to order quantity and process complexity.
Are your 3D printed parts suitable for functional testing?
Not all 3d printing parts can pass functional testing. Pls let me know your testing request, then we will evaluate your project seriously. If your parts construction and material can meet your request, we will let you know.
Do you provide design optimization and DFM advice for 3D models?
Yes. Our professional engineering team provides free DFM review for all 3D printing orders. We will check unreasonable structures such as overly thin walls, closed cavities, unreasonable support positions, and fragile structures, and give targeted optimization suggestions to improve printing yield, reduce production costs, and ensure perfect part forming.
