Every Material Has a Purpose
One of the most common questions new FDM users ask is: "Which filament should I use?" This guide breaks down the four most popular filament types — PLA+, PETG, ABS, and TPU — with practical advice for each application.
The FDM Filament Family
| Material | Ease | Strength | Heat Resistance | Flex | Best For |
|---|---|---|---|---|---|
| PLA+ | ★★★★★ | ★★★ | ★★ | ★ | Prototypes, decorative |
| PETG | ★★★★ | ★★★★ | ★★★ | ★★ | Functional, outdoor |
| ABS | ★★★ | ★★★★ | ★★★★ | ★★ | Engineering, enclosures |
| TPU 95A | ★★★ | ★★★ | ★★ | ★★★★★ | Flexible parts, seals |
1. PLA+ — The Everyday Champion
ANTINSKY PLA+ Filament is the most forgiving FDM material. It prints at 190-220°C, requires no heated bed, and produces minimal warping.
Best Applications
- Figurines, cosplay props, display models
- Prototyping and design verification
- Jigs and fixtures (non-load-bearing)
- Educational projects
PLA+ Print Settings
| Parameter | Recommended |
|---|---|
| Nozzle Temp | 195-215°C |
| Bed Temp | 50-60°C |
| Speed | 50-100 mm/s |
| Fan | 100% (after first 3 layers) |
| Retraction | 4-6mm @ 40mm/s (Bowden) / 0.8mm @ 35mm/s (Direct) |
Pro Tip: ANTINSKY PLA+ comes in 46 colors with excellent layer adhesion.
2. PETG — The Functional All-Rounder
ANTINSKY PETG combines PLA's printability with better strength and UV stability.
Best Applications
- Mechanical brackets and enclosures
- Outdoor signs and garden items
- RC car and drone parts
- Kitchen organizers
PETG Print Settings
| Parameter | Recommended |
|---|---|
| Nozzle Temp | 230-250°C |
| Bed Temp | 70-80°C |
| Speed | 40-70 mm/s |
| Fan | 30-50% |
| Retraction | 3-5mm @ 30mm/s |
⚠️ PETG absorbs moisture rapidly — always dry fresh spools. Use a glue stick to prevent over-adhesion.
3. ABS — The Engineering Workhorse
ANTINSKY ABS delivers exceptional strength and heat resistance (up to 95°C).
Best Applications
- Automotive interior parts
- Electronic enclosures
- Tools and workshop accessories
- Parts needing acetone smoothing
ABS Print Settings
| Parameter | Recommended |
|---|---|
| Nozzle Temp | 230-260°C |
| Bed Temp | 90-110°C |
| Enclosure | Required (40-50°C inside) |
| Fan | Off for first 10 layers, then 20-30% |
| Retraction | 4-7mm @ 40mm/s |
⚠️ Requires enclosed printer and good ventilation.
4. TPU 95A — Flexibility Where Needed
ANTINSKY TPU 95A offers excellent flexibility for functional applications.
Best Applications
- Phone cases and protective covers
- Gaskets and vibration dampeners
- Flexible hinges
- Wearable parts and straps
TPU Print Settings
| Parameter | Recommended |
|---|---|
| Nozzle Temp | 220-240°C |
| Bed Temp | 40-60°C |
| Speed | 15-30 mm/s |
| Fan | 50-70% |
| Retraction | 1-2mm @ 20mm/s |
Pro Tip: TPU is difficult with Bowden extruders. Use direct-drive and dry before printing.
