What Is Plastic 3D Printing?
Plastic 3D Printing—also known as Polymer Printing—is a subset of Additive Manufacturing (AM), a process that builds objects through Layer-by-Layer Fabrication rather than subtracting material (e.g., cutting or drilling). Unlike traditional manufacturing, it transforms digital designs into physical parts directly, eliminating the need for expensive molds.
The most common Plastic 3D Printing Process variants include:
| Technology | Key Advantage | Ideal Use Case |
| Fused Deposition Modeling (FDM) | Low cost, wide material range (e.g., PLA, ABS) | Prototyping, consumer products |
| Stereolithography (SLA) | High surface detail, smooth finishes | Jewelry, medical models |
| Selective Laser Sintering (SLS) | Strong, durable parts (e.g., nylon) | Industrial components, functional parts |
| Digital Light Processing (DLP) | Fast printing speed, high resolution | Dental aligners, small intricate parts |

The Plastic 3D Printing Workflow (Process)
A successful 3D print relies on a structured 3D Printing Workflow. At Yigu Technology, we follow these key steps to deliver reliable results:
- Design for Additive Manufacturing (DfAM): Optimize designs for 3D printing (e.g., reducing overhangs, adding support structures) to avoid defects and improve part strength.
- CAD Modeling: Create a 3D digital model using software like SolidWorks or Fusion 360—this is the blueprint for your part.
- STL File Preparation: Convert the CAD model to an STL file (a standard format for 3D printing) and repair any mesh errors (e.g., missing faces).
- Slicing Software: Use tools like Cura or PrusaSlicer to split the STL file into thin layers (0.1–0.3mm) and set print parameters (e.g., speed, temperature).
- Print Orientation: Choose the best orientation for the part to balance strength, surface quality, and support material usage.
- Support Structures: Add temporary supports for overhangs (45°+ angles) to prevent warping during printing—these are removed post-processing.
- Printing: The 3D printer builds the part layer by layer using the selected plastic material (e.g., PLA, nylon).
- Post-Processing: Clean the part (remove supports, sand rough edges) and apply surface treatments (e.g., painting, vapor smoothing) if needed.
- Quality Control: Inspect the part for dimensional accuracy (using calipers or 3D scanners) and functional performance (e.g., stress testing).
Iterative Design Process: Refine the design based on test results—critical for prototyping and ensuring the final part meets your needs.

Our team provides Material Selection guidance to match your project’s needs—whether you prioritize cost, strength, flexibility, or sustainability.
Surface Treatment for Plastic 3D Prints
Post-processing and Surface Treatment enhance the aesthetic and functional performance of 3D prints. Yigu Technology offers the following techniques:
- Sanding: Use sandpaper (80–400 grit) to smooth layer lines and rough edges—ideal for preparing parts for painting.
- Painting: Apply acrylic or spray paint to match brand colors or improve UV resistance—common for consumer products and art.
- Coating: Add protective coatings (e.g., clear varnish, epoxy) to increase durability and chemical resistance.
- Plating: Deposit metal layers (e.g., chrome, nickel) onto plastic parts for a metallic finish—used in automotive and consumer electronics.
- Polishing: Use compounds or buffing wheels to create a glossy surface—popular for jewelry and decorative parts.
- Texturing: Add patterns (e.g., matte, grippy) to improve grip or hide layer lines—useful for handles or medical devices.
- Vapor Smoothing: Expose parts to solvent vapor (e.g., acetone for ABS) to melt surface layers, creating a smooth finish.
- Chemical Etching: Use mild chemicals to remove surface imperfections without damaging the part’s structure.
- Primer Application: Apply a primer before painting to improve paint adhesion and cover layer lines.
- Surface Hardening: Treat parts with heat or chemicals to increase scratch resistance—critical for high-wear components.
These treatments not only boost Aesthetic Enhancement but also add Functional Coatings that extend part lifespan.
Tolerances and Precision in Plastic 3D Printing
Tolerances (the allowable deviation from a part’s intended dimensions) are vital for parts that need to fit or function with other components. Yigu Technology ensures Dimensional Accuracy through:
| Factor | Our Standard | Industry Benchmark |
| Tolerance Levels | ±0.1mm for small parts (<100mm); ±0.1% for large parts | ±0.2mm / ±0.2% |
| Layer Thickness | 0.1–0.3mm (adjustable for speed/quality) | 0.2–0.4mm |
| Print Resolution | Up to 50μm (for SLA/DLP) | 100–200μm |
| Material Shrinkage | Minimized (e.g., 1–2% for PLA; 3–5% for ABS) | 2–6% (untreated) |
| Thermal Expansion | Controlled via heated enclosures (for ABS/PC) | Uncontrolled (leads to warping) |
We use advanced Measurement Techniques (e.g., coordinate measuring machines, 3D scanners) and Quality Assurance protocols to verify tolerances—ensuring parts meet your exact specifications.

Manufacturing Techniques: Additive vs. Subtractive
Understanding the difference between Additive vs. Subtractive Manufacturing helps you choose the right method for your project:
| Aspect | Additive Manufacturing (Plastic 3D Printing) | Subtractive Manufacturing (e.g., CNC Machining) |
| Material Usage | Minimal waste (only uses needed material) | High waste (cuts material from a solid block) |
| Complexity | Handles intricate designs (lattices, channels) | Limited by tool access (hard to make internal features) |
| Lead Time | Fast (prototypes in days) | Slow (requires tool setup, machining time) |
| Cost (Small Batches) | Low (no mold costs) | High (tooling + material waste) |
| Cost (Large Batches) | High (per-part cost stays the same) | Low (per-part cost decreases with volume) |
| Tolerances | Good (±0.1mm) | Excellent (±0.01mm) |
Yigu Technology also offers Hybrid Manufacturing (combining 3D printing with machining) for parts that need high precision. Other techniques we use include Binder Jetting (for metal-plastic composites) and Material Jetting (for multi-color prints).
