How important is auto-leveling on a 3D printer?
Automatic leveling technology has greatly improved the reliability and efficiency of 3D printing, which is especially important for beginners and mass production. It ensures perfect first-layer adhesion by compensating for uneven bed surfaces in real time, reducing printing

Can Polyetherimide Filament Be 3d Printing?
Polyetherimide (PEI) filament is not only a viable option for 3D printing, but also a revolutionary material for high-performance industrial manufacturing. Through high-temperature printers (nozzle>350°C, hot bed>150°C) with closed chambers and negative pressure exhaust systems

What is the purpose of knurling?
The core purpose of knurling is to permanently change the surface characteristics of the workpiece through mechanical deformation without adding any additional materials, which not only enhances the friction (friction coefficient can be increased by 300%-500%), but also achieves anti-slip function.

PLA vs. PLA+: Differences and Comparisons
The choice between PLA and PLA+ is not a simple “upgrade or not”, but a precise trade-off based on the application scenario. PLA is still an ideal choice for low-intensity scenarios such as education and decorative models due to its low cost, ease of use and environmental protection;

What is the difference between SLA and DLP?
The essential difference between DLP (digital light processing) and SLA (stereolithography) stems from the technical principle: DLP uses a projector to solidify the resin in a whole layer, which is fast and low-cost, and is suitable for mass production of small and medium-sized parts (such as invisible braces); while SLA relies on laser point-by-point scanning,

What is the difference between urethane casting and injection molding?
The core difference between urethane casting and injection molding lies in material properties, production efficiency and precision level. Urethane casting uses room temperature curing resin, which is fast and low cost (especially for small batches), but is limited by strength (≤80 MPa) and precision (±0.3 mm), and is suitable for flexible, low-load short-term parts (such as cushions,

Types of Thread Taps: How to Choose the Right One?
Choosing the right thread tap requires comprehensive consideration of four key factors: processing materials, hole characteristics, production batch and precision requirements. For hard materials such as steel, cobalt-containing high-speed steel or coated taps should be used.

What Grounds Jets? Brake Discs & Retraction Actuators Under Fire
The core causes of frequent groundings of jet aircraft are the thermal decay effect of brake discs and hydraulic hysteresis of retraction actuators: Emirates Boeing 777 failed due to delamination of carbon fiber brake discs at 1200℃ (NTSB report AAR-24/01), exposing the thermal resistance limit of traditional materials; Airbus A320neo fleet caused a 300% surge in the risk of landing

What is HIPS 3D printer filament？
HIPS (High Impact Polystyrene) is an engineering plastic optimized for 3D printing that combines high strength, impact resistance, and soluble support properties. It is suitable for dual-printhead printing, often used as a support material with ABS, and can be easily dissolved with limonene solvent,
