Industrial 3d printing builder

Industrial printing pays when parts are complex, low-volume or need fast change. It loses to moulding at high volume.

• Good fits include custom brackets, jigs and fixtures, spare parts that are no longer made, lightweight lattices, and medical and dental models.
• Poor fits are thousands of identical simple parts, where moulding or bulk machining costs less per part.
• Compare three routes for one part: machining, moulding, printing; write cost per part at 10, 100 and 10,000 units.
• Find customers among machine shops, repair depots, clinics, product designers and makers of low-volume equipment.
• Check the build file with a slicer preview before printing, and keep the preview image with the job record.
• Ask the customer for the part's size, load, working temperature, finish and number needed, and write the answers on the quote request.
• Count total cost, not only the unit price: moulding adds a tool cost up front, so divide it by the number of parts.

Activity. Compare the three routes for two real parts and recommend one.

Standard to meet. Cost at three volumes shown for each part.

Printing with metal powders, resins and heat has real hazards and quality rules.

• Metal powders can burn or explode; follow storage, grounding and fire rules and keep safety data sheets.
• Resins and fumes need ventilation, gloves and eye protection; dispose of waste as hazardous if rules say so.
• Parts for aircraft, medical and pressure uses need certified material and process records; check the customer's standard before you quote.
• Provincial workplace health and safety rules require trained machine operators; keep training records and check the provincial rule for your trade.
• Name one test per load direction (pull, bend, impact) and run it on a printed coupon before you quote a safety-related part.
• Put the safety data sheet for each material in a binder at the machine, and teach staff to find the first-aid and spill steps.
• Check the provincial rule for noise, air quality and waste handling in your building, and ask the landlord and insurer what they require.

Activity. Build a rules table for a print shop of three people.

Standard to meet. Give every hazard row a control and a training record.

Quality comes from good files, good settings and careful finishing.

• Check the model: closed surface, wall thickness above the machine's minimum, overhangs supported.
• Orient the part to put strength along the load and minimise supports.
• Record layer height, material lot, temperature, speed and build time for each job.
• Finish: remove supports, heat-treat or cure if needed, smooth, measure against the drawing.
• Ask each customer what happens if the part fails; use the answer to set inspection depth.
• Print a small test piece first to check fit when a tolerance is tight, and measure it before you print the full part.
• Dry materials that absorb moisture and store them in sealed boxes; record the storage and drying time on the job sheet.

Activity. Print one part two ways, test and record results.

Standard to meet. Record settings, measure both parts and justify the best orientation.

Machine hours, material, labour and failure rate set the price.

• Machine rate = machine cost divided by expected hours of use, plus power and maintenance per hour.
• Add the material used including supports and waste, post-processing labour and inspection.
• Add a failure allowance: if 1 in 10 builds fails, add about 11% to cost.
• Set the quote price as cost plus target margin, and show the customer a breakdown.
• Margin = price minus cost. Break-even parts = monthly fixed cost divided by margin per part, rounded up.
• Test your quote with a 20% rise in failures and with a 10% rise in material price. Write what happens to margin.
• Keep a monthly list of the three parts you could not print well and why; it guides your next training topic.

Activity. Build the quote sheet and test a 20% rise in failures.

Standard to meet. Show units and include a failure allowance.

Customers trust parts they can trace.

• Give every part a job number tied to material lot and build file.
• Measure critical dimensions with calibrated tools and keep certificates.
• Schedule maintenance: laser or nozzle checks, filter changes, calibration prints.
• Track first-pass yield: good parts divided by started parts.
• Time every job from file received to part shipped; the median is your honest lead time.
• Calibrate scales and callipers at fixed dates and log them.
• Keep rejected parts in a labelled bin until you have written the cause, then recycle or dispose as the rules require.

Activity. Keep a 4-week shop log with yield.

Standard to meet. Trace every job to a lot and choose action from data.

Show the part, the saving and the speed.

• Offer a sample print of the customer's own part at low cost.
• Quote with lead time in days; fast turnaround is your edge.
• Partner with designers who can redesign parts for printing.
• Join local manufacturing clusters and trade days.
• Show a before-and-after case: the old part, the printed part, the time saved and the cost compared.
• Write a one-page capability sheet: machines, materials, size limits, tolerances and lead times.
• Follow up each sample within three days, ask one question about the fit and record the answer.

Activity. Run a 4-week funnel and book 5 conversations.

Standard to meet. Record funnel numbers.

Printing makes copying easy; handle design rights with care.

• Print only designs you own or have a licence for.
• Refuse parts that can be misused to harm, such as weapons components.
• Keep customer files secure and delete on agreement.
• Keep a risk register that covers machine breakdown, a powder incident, a customer file leak and the loss of one big customer.
• Offer one-page design tips so customers send better files.
• Put ownership of designs in the quote: who owns the file, the part and any improvements. Ask a lawyer to review your terms.
• Write down what you will say to a customer asking for a part you must refuse, and keep a log of refusals.

Activity. Write an eight-row risk register.

Standard to meet. Give each row an owner and review date.

Prove a small cell before you add machines.

• Pilot 60 days with 3 customers and measures: yield, turnaround, margin.
• Stop rule: margin below 30% after 40 jobs means re-quote or stop.
• Add a second machine only when the first runs above 60% use.
• Plan funding from manufacturing grants and an equipment lease.
• Send a feedback message three days after delivery and file the answer.
• Machine use = hours printing divided by hours available; track it weekly from the machine log.
• Check the funding programmes' rules and dates yourself, and compare lease cost with buying.

Activity. Run the pilot and present review.

Standard to meet. Review has measures and decision.

L1: Technology aware learner. You can define: name the main terms, people and rules of industrial 3d printing builder. Focus module: Choose parts that suit printing (Understand, 6 h). Industrial printing pays when parts are complex, low-volume or need fast change. It loses to moulding at high volume. Key points: Good fits include custom brackets, jigs and fixtures, spare parts that are no longer made, lightweight lattices, and medical and dental models. Poor fits are thousands of identical simple parts, where moulding or bulk machining costs less per part. Compare three routes for one part: machining, moulding, printing; write cost per part at 10, 100 and 10,000 units. Find customers among machine shops, repair depots, clinics, product designers and makers of low-volume equipment. Check the build file with a slicer preview before printing, and keep the preview image with the job record. Ask the customer for the part's size, load, working temperature, finish and number needed, and write the answers on the quote request. Count total cost, not only the unit price: moulding adds a tool cost up front, so divide it by the number of parts.

Speaker notes. Teach: open with the worked example. A bracket costs 260 to machine, 12 to mould (tooling 18,000) and 150 to print. For 10 parts, printing costs 1,500, machining 2,600 and moulding 18,000 + 120 = 18,120. Moulding only beats printing past 18,000 / (150 - 12) = about 131 parts; at 5,000 parts moulding is far cheaper per part. Then set the activity: Compare the three routes for two real parts and recommend one. Mark against the standard: Cost at three volumes shown for each part. Check at this level: Name two parts that fit printing. Model answer: Custom jigs, spare parts or lattices. Level note: Start here if new. Evidence: a one-page glossary and a visit or interview note.

L2: Lab or shop assistant. You can describe: explain how industrial 3d printing builder works from first contact to result. Focus module: Know print rules, safety and standards (Apply, 6 h). Printing with metal powders, resins and heat has real hazards and quality rules. Key points: Metal powders can burn or explode; follow storage, grounding and fire rules and keep safety data sheets. Resins and fumes need ventilation, gloves and eye protection; dispose of waste as hazardous if rules say so. Parts for aircraft, medical and pressure uses need certified material and process records; check the customer's standard before you quote. Provincial workplace health and safety rules require trained machine operators; keep training records and check the provincial rule for your trade. Name one test per load direction (pull, bend, impact) and run it on a printed coupon before you quote a safety-related part. Put the safety data sheet for each material in a binder at the machine, and teach staff to find the first-aid and spill steps. Check the provincial rule for noise, air quality and waste handling in your building, and ask the landlord and insurer what they require.

Speaker notes. Teach: open with the worked example. Row: 'Store titanium powder | fire code and provincial workplace safety rules | sealed containers, grounded, signage | before first delivery | inspection note'. For a 3-person shop with 4 materials, that is 4 safety data sheets and 3 training records, 7 documents to file before the first job. Then set the activity: Build a rules table for a print shop of three people. Mark against the standard: Give every hazard row a control and a training record. Check at this level: Why get a customer's standard first? Model answer: Certified uses need specific material and records. Level note: Evidence: a flow chart and a two-minute spoken explanation.

L3: Technician. You can apply: carry out a routine task in industrial 3d printing builder to a written standard. Focus module: Prepare, print and finish a part (Apply, 10 h). Quality comes from good files, good settings and careful finishing. Key points: Check the model: closed surface, wall thickness above the machine's minimum, overhangs supported. Orient the part to put strength along the load and minimise supports. Record layer height, material lot, temperature, speed and build time for each job. Finish: remove supports, heat-treat or cure if needed, smooth, measure against the drawing. Ask each customer what happens if the part fails; use the answer to set inspection depth. Print a small test piece first to check fit when a tolerance is tight, and measure it before you print the full part. Dry materials that absorb moisture and store them in sealed boxes; record the storage and drying time on the job sheet.

Speaker notes. Teach: open with the worked example. A bracket is printed flat and fails along layers at 600 N; printed upright it holds 1,100 N. That is 1,100 / 600 = 1.83 times stronger, so orientation almost doubled strength. Record both results and the angle in the job sheet. Then set the activity: Print one part two ways, test and record results. Mark against the standard: Record settings, measure both parts and justify the best orientation. Check at this level: Why orient a part carefully? Model answer: Strength differs along and across layers. Level note: Evidence: a supervised task record that meets the standard once.

L4: Product engineer or builder. You can analyse: diagnose why an industrial 3d printing builder result missed its target and fix it. Focus module: Price a job and prove margin (Evaluate, 8 h). Machine hours, material, labour and failure rate set the price. Key points: Machine rate = machine cost divided by expected hours of use, plus power and maintenance per hour. Add the material used including supports and waste, post-processing labour and inspection. Add a failure allowance: if 1 in 10 builds fails, add about 11% to cost. Set the quote price as cost plus target margin, and show the customer a breakdown. Margin = price minus cost. Break-even parts = monthly fixed cost divided by margin per part, rounded up. Test your quote with a 20% rise in failures and with a 10% rise in material price. Write what happens to margin. Keep a monthly list of the three parts you could not print well and why; it guides your next training topic.

Speaker notes. Teach: open with the worked example. Cost per part: machine time 70, material 45, post-processing 25, inspection 10 = 150; a 1 in 10 failure rate adds 150 x 0.111 = about 17, so 167. Price 420 gives margin 253 (60%). Fixed cost 25,000 a month breaks even at 25,000 / 253 = about 99 parts. If failures rise from 10% to 12%, the allowance becomes about 20 and margin falls to 250. Teaching figures in CAD. Then set the activity: Build the quote sheet and test a 20% rise in failures. Mark against the standard: Show units and include a failure allowance. Check at this level: What is a failure allowance? Model answer: Extra cost added for builds that fail. Level note: Evidence: a fault or gap analysis with a fix and a repeat test. This course targets this level.

L5: Senior engineer or line lead. You can evaluate: judge options for industrial 3d printing builder against cost, risk and quality. Focus module: Win customers and design partners (Create, 6 h). Show the part, the saving and the speed. Key points: Offer a sample print of the customer's own part at low cost. Quote with lead time in days; fast turnaround is your edge. Partner with designers who can redesign parts for printing. Join local manufacturing clusters and trade days. Show a before-and-after case: the old part, the printed part, the time saved and the cost compared. Write a one-page capability sheet: machines, materials, size limits, tolerances and lead times. Follow up each sample within three days, ask one question about the fit and record the answer.

Speaker notes. Teach: open with the worked example. Funnel: 25 shops visited, 9 samples, 4 repeat jobs. Rates: samples 9/25 = 36%, repeats 4/9 = 44%. Overall 4 of 25 visits (16%) became repeat customers, so 50 visits might give about 8. Then set the activity: Run a 4-week funnel and book 5 conversations. Mark against the standard: Record funnel numbers. Check at this level (this question is covered in module 1: Choose parts that suit printing): When does printing beat moulding? Model answer: At low volume, with complex shapes or fast change. Level note: Evidence: an options paper with numbers and a recommendation defended to a panel.

L6: Programme or plant manager. You can create: design and pilot a new offer or process in industrial 3d printing builder. Focus module: Manage ethics, IP and risk (Evaluate, 6 h). Printing makes copying easy; handle design rights with care. Key points: Print only designs you own or have a licence for. Refuse parts that can be misused to harm, such as weapons components. Keep customer files secure and delete on agreement. Keep a risk register that covers machine breakdown, a powder incident, a customer file leak and the loss of one big customer. Offer one-page design tips so customers send better files. Put ownership of designs in the quote: who owns the file, the part and any improvements. Ask a lawyer to review your terms. Write down what you will say to a customer asking for a part you must refuse, and keep a log of refusals.

Speaker notes. Teach: open with the worked example. Risk: 'Single machine breaks for 2 weeks | 3 x 4 = 12 | service contract and partner shop agreement | owner | quarterly'. If that machine earns 10,000 a week, a two-week stop puts 20,000 of sales at risk, which is why the partner agreement matters. Then set the activity: Write an eight-row risk register. Mark against the standard: Give each row an owner and review date. Check at this level: What can you refuse on ethics grounds? Model answer: Parts that could be used to harm people. Level note: Evidence: a pilot with measured results over at least 30 days.

L7: Technology founder or director. You can lead: run a team or business in industrial 3d printing builder and develop others. Focus module: Pilot and scale the shop (Create, 8 h). Prove a small cell before you add machines. Key points: Pilot 60 days with 3 customers and measures: yield, turnaround, margin. Stop rule: margin below 30% after 40 jobs means re-quote or stop. Add a second machine only when the first runs above 60% use. Plan funding from manufacturing grants and an equipment lease. Send a feedback message three days after delivery and file the answer. Machine use = hours printing divided by hours available; track it weekly from the machine log. Check the funding programmes' rules and dates yourself, and compare lease cost with buying.

Speaker notes. Teach: open with the worked example. Result: 41 jobs, margin 44%, use 58%. Margin is above the 30% stop line, but use is below 60%; decision: hold until use passes 60%. At 160 machine hours available a week, 58% means about 93 hours printing and 60% means 96 hours. Then set the activity: Run the pilot and present review. Mark against the standard: Review has measures and decision. Check at this level: When add a second machine? Model answer: When the first runs above about 60% use. Level note: Evidence: a record of results over a year and of people you have coached to a higher level.
