Top 5 Heat-Resistant 3D Printing Filaments Compared

When Regular Filament Just Doesn’t Cut It You’ve 3D printed a functional bracket for a car engine bay. It fits perfectly, looks great, and then warps into a banana-shape after a week under the hood. That’s the danger of underestimating heat. If you're building automotive components, enclosures near motors, molds, or even kitchenware, using the wrong filament can lead to deformation, brittleness, or outright failure when exposed to heat. So, you already know the solution: Choosing the right heat-resist......

Flexible 3D Printing Filament Types: TPU, TPE & Soft PLA Guide

You’re probably here because rigid PLA just won’t cut it. Maybe your print needs to flex, bounce back, stretch, or just not snap in half under pressure. Whether it’s a phone case, a gasket, a soft robot joint, or some weird wearable idea, you’re now in the world of flexible 3D printing filaments. But here’s the problem: Flexible filaments like TPU, TPE, or soft PLA aren’t all the same. Some are rubbery and forgiving, others are more like bendy plastic. Some will glide through your printer like a dream......

What Is LW PLA? How Lightweight PLA Works and When to Use It

The first time you print with LW PLA, you will genuinely think that you grabbed the wrong spool off the shelf. Pick the part up off the bed and it will feel hollow. But it isn't. Same infill setting, same model, just... lighter. Sometimes, depending on print temperature and expansion ratio, it can reduce part weight by approximately 20–50%. So what's actually going on? This guide walks through what LW PLA is, why it does what it does, and the settings that'll get you there without fighting the printer......

Is MJF Suitable for Production Parts? A Practical Engineer’s Guide

Why Engineers Choose MJF for Production Parts MJF didn’t rise just as a prototyping machine. It climbed straight into real manufacturing. The making of HP Multi Jet Fusion 3D printed parts uses a fine-grained nylon powder fused with a chemical fusing agent and precision infrared heating. That means consistent, repeatable parts without visible stepping or layered fragility. Dimensional accuracy typically sits around ±0.2 mm for small features, depending on geometry, orientation, and part size, tight en......

Choosing the Right ESD Filament for Your Application

Introduction Somewhere in an electronics assembly facility right now, someone is printing a fixture on a desktop 3D printer using standard PLA. It looks fine. It fits the board. And every time a PCB gets placed in it, static charge builds on that perfectly smooth, perfectly insulating plastic surface, right next to components sensitive to discharges that humans can't even feel. ESD filament exists specifically for this problem. It's not a premium upgrade to standard filament. It's a different material......

ABS-ESD Plastic: Properties, Applications & Selection Guide

Introduction ABS-ESD is a specialized engineering ABS plastic developed for static-sensitive environments. Most engineers encounter ABS-ESD for the first time when a PCB fixture fails an ESD audit or a customer rejects a housing because it's not made from ESD safe ABS. The part was dimensionally correct. The material was wrong. ABS-ESD plastic solves a specific problem, static charge accumulating on parts that contact or sit near electronics. It does that job well, it 3D prints reliably, and it costs ......

ABS vs ABS-ESD: Key Differences and How to Choose the Right Material

Introduction Standard ABS is the best choice for most general engineering parts. Choose ABS-ESD only when your application requires protection against electrostatic discharge (ESD), such as PCB fixtures, SMT assembly jigs, or semiconductor tooling. Standard ABS and ABS-ESD look similar on a spec sheet. They print the same way, cost about the same at JLC3DP, and produce parts with similar surface finish. The difference that matters is invisible, one accumulates static charge on every surface, and the o......

ESD Plastic Materials: A Practical Guide for Engineers

Key Takeaways ESD plastic controls charge: It uses conductive or dissipative additives to let static charge flow away safely instead of building to a damaging discharge. Three categories by resistivity: Conductive (<10⁵ Ω/sq), static dissipative (10⁵–10⁹ Ω/sq), and anti-static (10⁹–10¹² Ω/sq) each serve different roles. Static dissipative is the usual target: Most electronics handling fixtures use the 10⁶–10⁸ Ω/sq range for controlled, non-damaging dissipation. Match material to the full application: ......

Why Use PEEK 3D Printing? Benefits, Applications & Challenges

Most engineering materials get chosen because they're available, familiar, or cheap. PEEK gets chosen because nothing else works. When an engineer specifies PEEK 3D printing, it's almost always because the part needs to survive conditions that would disqualify every other plastic on the shortlist, sustained heat above 200℃, aggressive chemicals, sterilization cycles, or mechanical loads that other polymers handle poorly over time. PEEK 3D printed parts aren't “prototype outputs”. They're functional en......

Why MJF Nylon Parts Feel Weak: Strength vs Stiffness vs Finish

If MJF nylon parts feel weaker than expected, it’s usually not because “MJF isn’t strong.” It’s because strength, stiffness, and surface finish are being lumped together as one vague idea of quality. They’re not the same thing. A part can be stiff but brittle. Strong but visually rough. Smooth but mechanically average.
