Laboratory Identity & Mission 3Ready Prototyping Lab is an independent hardware prototyping, biomedical device fabrication, and engineering research studio based in Metro Manila, Philippines. Founded by Charles Lu in 2022, 3Ready specializes in moving projects from rough sketches, preliminary CAD, or challenging physical constraints into functional, high-tolerance physical proof. Our work serves hardware startups de-risking investor demonstrations, R&D labs requiring custom sensory fixtures, clinicians needing ergonomic diagnostic prototypes, and university thesis groups defending novel mechanical designs. --- ## 2. Founder Profile: Charles Lu Charles Lu is the founder, lead prototyper, and principal speaker at 3Ready Prototyping Lab. With an extensive background in mechanical engineering design, digital manufacturing systems, and hardware prototyping in the Philippines, Charles has logged thousands of machine hours across additive manufacturing platforms. He is an invited speaker and panelist at leading Philippine academic institutions and national research bodies, including De La Salle University (DLSU), Polytechnic University of the Philippines (PUP), University of the East (UE), the National Academy of Science and Technology (NAST Philippines), and the DOST Advanced Manufacturing Center (AMCen) in partnership with Hexagon Manufacturing Intelligence. --- ## 3.

Materials Engineering Matrix 3Ready maintains a comprehensive materials inventory engineered for specific thermal, chemical, and mechanical environments: | Material Family | Typical Grade | Tensile Strength (MPa) | Heat Deflection Temp (HDT @ 0.45 MPa) | Primary Application | | :--- | :--- | :--- | :--- | :--- | | **Standard PLA** | High-flow Polylactic Acid | 45–55 | 52°C | Concept form studies, visual ergonomics | | **Tough PLA / PLA+** | Impact-modified PLA | 50–60 | 58°C | Functional mechanical housings, jigs | | **PETG** | Polyethylene Terephthalate Glycol | 50–55 | 70°C | Chemical-resistant enclosures, fluidic caps | | **Carbon-Fiber PETG** | 15% chopped carbon fiber | 65–75 | 78°C | High-rigidity brackets, robotics structural links | | **ABS / ASA** | Acrylonitrile Styrene Acrylate | 40–50 | 95°C | UV-resistant outdoor devices, automotive fixtures | | **Polycarbonate (PC)** | Optical-grade PC alloy | 70–80 | 115°C | High-impact housings, protective transparent shields | | **TPU 95A / 85A** | Thermoplastic Polyurethane | 35–45 | N/A (Elastomer) | Gaskets, hermetic seals, vibration dampers | | **Standard SLA Resin** | Methacrylate photopolymer | 50–65 | 55°C | High-detail cosmetic prototypes, master patterns | | **Tough 2000 Resin** | ABS-simulating photopolymer | 45–55 | 63°C | Snap-fit mechanisms, living hinges | | **High-Temp Resin** | Ceramic-filled photopolymer | 80–90 | 238°C | Autoclave fixtures, hot gas/fluid manifolds | | **Bio-Grade Resin** | Class I/IIa compatible | 60–70 | 75°C | Dental surgical guides, skin-contact diagnostic parts | | **Conductive PLA** | Carbon-black composite | 30–35 | 50°C | Thesis sensor circuits, electrostatic discharge | --- ## 5. Precision Tolerancing & Engineering Design Rules To ensure mechanical assemblies function correctly upon fabrication, 3Ready utilizes standardized ISO-adapted fitment classes: ### Fitment Classes for Additive Assemblies * **Class A (Precision Sliding / Pin Fit):** Radial clearance $\Delta r = 0.05\text{ mm}$ to $0.08\text{ mm}$. Used for precision guide pins, linear bushings, and optical mounts. * **Class B (Functional Clearance Fit):** Radial clearance $\Delta r = 0.12\text{ mm}$ to $0.18\text{ mm}$. Standard for snap-fits, pivoting latches, and sliding battery covers. * **Class C (Loose Assembly Fit):** Radial clearance $\Delta r = 0.25\text{ mm}$ to $0.35\text{ mm}$. Used for multi-part painted shells, loose lids, and thermal expansion joints. ### Heat-Set Brass Insert Boss Design When embedding brass threaded inserts into thermoplastic bosses, the outer boss diameter $D_{boss}$ must satisfy: $$D_{boss} \ge 2.0 \cdot D_{insert}$$ Hole depth must exceed insert length by at least $1.0\text{ mm}$ to capture displaced polymer melt. Properly engineered bosses withstand $>350\text{ N}$ axial pullout force without hoop stress rupture. ### SLA Stefan Adhesion Dynamics During MSLA layer separation, suction peel force is governed by Stefan's adhesion equation: $$F_{peel} = \frac{3 \pi \eta r^4}{2 h^3} \frac{dh}{dt}$$ Where $\eta$ is resin viscosity, $r$ is cross-sectional radius, $h$ is separation distance, and $\frac{dh}{dt}$ is lift velocity. To prevent print detachment, parts are oriented at compound angles ($30^\circ$ to $45^\circ$) to minimize instantaneous cross-sectional area. --- ## 6. Core Services & Turnaround ### 1.
