Knowledge base
The Arterki engineering blog
Practical guides for people who order parts. We publish engineering notes on CNC machining, 3D printing, injection molding and rapid tooling, material selection, heat treatment and inspection — the decisions that show up on your drawings and in your quotes. Every post is written by the engineers who run the equipment, and every capability mentioned is stated the way a drawing would state it: with a number.
New posts are added regularly. Here is what is on the site and coming next.
Can You 3D Print Injection Molds — and When Should You?
Read the guideABS vs PLA for 3D Printed Parts
PLA prints clean but softens near 60 °C; ABS takes heat and impact but warps without care. Strength, tolerances, PETG and food-contact questions, settled in one comparison.
Read the guideWhat Is Electric Discharge Machining?
EDM erodes hardened steel with sparks, not cutting edges. How the discharge circuit works, wire vs sinker EDM, and when sparks beat the mill — and when they never will.
Read the guideWhat Is Tempering, and When Do Engineers Need It?
Tempering rebalances hardness and toughness after quenching. What it does to your parts, how it differs from annealing and aging, and when to call it out on a drawing.
