What is 3D Printing?

How Does 3D Printing Work?
#1. Design
#2. 3D Print

#3. Post-Process

Plastic 3D Printing Processes

The three most established plastic 3D printing processes today are the following:
#Fused deposition modeling (FDM) 3D printers melt and extrude thermoplastic filaments, which a printer nozzle deposits layer by layer in the build area.
-Popular FDM 3D Printing Materials
#Stereolithography (SLA) 3D printers use a laser to cure thermosetting liquid resins into hardened plastic in a process called photopolymerization.
-Popular SLA 3D Printing Materials
#Selective laser sintering (SLS) 3D printers use a high-powered laser to fuse small particles of thermoplastic powder.

Why deeper texture requires a larger draft angle for injection molded parts
2026-10-27

When we quote an injection mold, surface finish and draft angle are two essential items that customers frequently inquire about. Mold surface treatment mainly falls into two categories: SPI polish finish and etched texture (graining). Different finishes carry different requirements for draft angle. Read More
2K Injection Handle: Dual Contrast Texture — Mold Finish or Post Spraying?
2026-10-26

Many overseas buyers ask the same question when they receive this two-shot handle sample: why one part of the handle is glossy and smooth, while the grip area delivers a fine matte soft-touch feeling?

Quite a few assume the matte texture comes from post-spray painting after injection molding. This is a common confusion in plastic surface finishing: in-mold texture vs post-treatment coating. Read More
Parting Lines in Injection Molding: What They Are, Where They Go & How We Minimize Them
2026-10-22

If you work with custom injection molded plastic parts, you have almost certainly seen a thin seam running along the edge of a component. This is the parting line (PL) — one of the most fundamental, and most misunderstood, features of injection molding.

Many buyers mistakenly think a parting line means the product is two separate pieces glued together. This is not true. The finished plastic part is molded as one single piece in one shot. The line simply marks where the two halves of the injection mold close and seal together before plastic is injected. Read More
Slides vs Lifters vs Collapsible Cores – How to Select Undercut Mechanisms for Injection Molds
2026-10-20

Plastic parts with undercuts cannot eject directly along the mold opening direction. Mold designers have three mainstream mechanical solutions: slides (side actions), lifters (angled ejectors), and collapsible cores. Many engineers confuse these three structures. This article explains their working principles, use cases, pros & cons, and selection logic for your DFM review and quoting. Read More
Injection Mold QC Inspection: CMM Measurement, First Article Check & Mold Pre-Shipment Inspection Workflow
2026-10-16

Quality control is the backbone of every reliable injection mold. A well-executed QC workflow catches dimensional errors, surface defects and assembly issues before the injection mold leaves our factory, avoiding costly rework and production delays for mass molding. Our mold QC system covers three critical stages: CMM coordinate measurement, first article inspection (FAI), and mold pre-shipment inspection. Read More
How to Improve Scratch Resistance for Injection Molded Plastic Parts
2026-10-13

Poor scratch resistance is one of the most common complaints for injection molded plastic products. Many base thermoplastics like ABS, PP and PA12 are relatively soft on the Mohs hardness scale. Fine dust, daily contact and friction will leave visible scratches easily.

There are multiple ways to boost scratch resistance for your injection molding parts. We can divide the solutions into 3 categories: material modification, mold & structure optimization, and post-mold surface finishing. Read More
Plastic Tile Surface Finishing Options for Your ABS Ribbed Panels
2026-10-09

When manufacturing decorative ribbed plastic tiles, choosing the right surface finish is critical. Your selection directly impacts appearance, unit cost, wear resistance, production yield and environmental compliance. For 3”×6”, 8mm thick ABS tiles with parallel ribs, especially for medium-to-large batch orders up to 73,000 pieces, there are 5 practical finishing solutions to consider. Read More
PA12 UV-Resistant Parts: Mold Design & Molding Guidelines
2026-10-08

PA12 (Polyamide 12 / Nylon 12) is widely selected for outdoor equipment because of its low moisture absorption, excellent low-temperature toughness and chemical resistance. When formulated with UV stabilizers, UV-resistant PA12 becomes an ideal material for vehicle tracking housings, outdoor sensor enclosures and exposed cargo safety components.

UV additives and PA12 base resin together bring unique challenges for mold design and molding. Improper tooling will cause yellowing, gas burns, silver streaks, warpage and dimensional drift. Read More
Common Defects of Medical Injection Parts: Flash, Fabric Shifting & Bubbles Analysis & Solutions from Injection Mold Perspective
2026-10-06

For fabric insert molding for disposable medical consumables like NPWT wound dressings, many defects are rooted in mold structure, machining tolerance, venting and locating design, instead of only molding machine parameters. Read More
Insert Molding vs Overmolding for Single-Use Medical Components
2026-09-30

Many medical R&D engineers confuse insert molding and overmolding. Both technologies combine multiple materials into one integrated part and eliminate manual assembly. However, they follow different manufacturing logic and fit different medical design requirements. Wrong selection may cause low yield, leakage risk and extended validation cycle for disposable medical consumables. Read More
