Project evaluation system for professional 3D printing services: from technical feasibility to cost accounting

The Importance and Objectives of Project Evaluation

Each customer's needs faced by professional 3D printing services are unique, and a systematic project evaluation is required to provide accurate service plans and quotations. The goal of project evaluation is to determine the technical feasibility of requirements, determine the optimal process solution, calculate service costs, predict delivery cycles, and identify potential risks. A sound evaluation system can avoid late rework, reduce customer complaints, and improve service quality and customer satisfaction. The assessment process is also an opportunity for in-depth communication with customers to discover their real needs, provide more professional advice, and build trusting relationships.

Dimensions of technical feasibility assessment

Technical feasibility assessment requires analyzing requirements from multiple dimensions. Model analysis, checking the integrity of the model file, patch quality, sealing, and identifying geometric features that may cause printing problems. Size evaluation to confirm whether the part size is within the printing range of the equipment and whether it needs to be printed in separate pieces. Characteristic analysis to check whether key parameters such as minimum wall thickness, minimum hole diameter, and suspension angle meet process requirements. Material matching, recommending suitable printing materials based on part usage and performance requirements. Process selection, comparing the accuracy, strength, cost and cycle of different processes, and recommending the optimal solution. Post-processing needs, evaluate support removal, surface treatment, machining, coating and other post-processing processes. Technical risk assessment, identify technical difficulties that may affect printing success, and formulate response plans.

Cost accounting model

Accurate cost accounting is the basis for reasonable quotation. The costing model should include the following elements: Material cost, calculated based on part volume and material unit price, taking into account support materials and material losses. Equipment cost, calculated based on printing time and equipment depreciation rate. Labor costs include labor time in pre-processing, print monitoring, post-processing, inspection, etc. Post-processing costs are calculated based on the complexity and time of the post-processing process. Quality costs include inspection, rework, scrap and other costs. Management costs, project management, communication and coordination and other indirect costs. Shipping costs, packaging and logistics fees. Cost accounting requires the establishment of standardized calculation methods and parameter libraries to ensure the consistency and accuracy of accounting results. For complex projects, it is recommended to conduct a comparative analysis of multiple options to provide customers with the most cost-effective option.

Delivery cycle assessment

Delivery cycle is the focus of customers, and accurate cycle assessment is the basis of service commitment. Cycle evaluation needs to consider: file processing time, model inspection, repair, slicing, etc. preparation time. Print the queuing time and estimate the waiting time based on existing orders. Printing time, calculate the actual printing time based on part parameters and process parameters. Post-processing time, the time required for each post-processing process. Inspection time, the time required for quality inspection. Packaging and shipping time is determined based on the customer's address and shipping method. Periodic evaluations need to leave room for unexpected situations, but they should not be overly conservative and affect competitiveness. It is recommended to establish a standard cycle commitment system, such as different levels of cycles and prices for standard services, expedited services, urgent services, etc.

Standardization of assessment processes

Standardized assessment processes can improve efficiency and consistency. It is recommended to establish the following processes: demand reception, unified reception channels, and recording customer information and demand details. Preliminary screening to quickly determine whether it is within the service scope and target customers. Technical assessment, a detailed technical feasibility analysis conducted by the technical team. Cost accounting, cost accounting based on technical solutions. Quotation approval, important projects or special quotations need to go through the approval process. Communicate with customers, explain plans, quotations and cycles to customers, and answer questions. Confirm the signing and sign the service agreement after the customer confirms. The evaluation process needs to be recorded in the system and historical data accumulated for analysis and optimization. Regularly review the assessment accuracy and continuously improve the assessment system.
